Do-it-yourself repair of cracks in plastic bumpers - methods and technology. How to seal a plastic bucket. Clear nail polish

Once upon a time, slate roofing was considered perhaps the most versatile: affordable, durable and unpretentious. Cheap and cheerful, as they say. But for all the strength of asbestos fibers, such sheets are not very resistant to mechanical stress: over time, many small cracks always appear on them, through which moisture easily seeps through.

Luckily, at least a slate roof doesn't corrode like a metal roof that rusts from the slightest scratch, but repairs will still need to be done from time to time. So how to close a crack in the slate and stop the further destruction of other sheets? Now we will understand everything in more detail.

Fragile slate is damaged quite easily:

  1. from impact loads. From careless walking on the roof.
  2. From microcracks due to falling tree branches.
  3. From mosses, lichens and other misfortunes. Moss and lichens, which are especially fond of slate, not only deprive it of its aesthetics, but also slowly destroy it!
  4. From time. Unfortunately, the service life slate roof are not large, and after 10-12 years the first cracks and holes appear.
  5. From constantly stagnant rainwater. Any roof, and not just slate, has weak spots around skylights and chimneys. Immediately pay attention to these elements - it is not difficult to seal them.
  6. The angle of the roof is not suitable for slate roofing.
  7. The laying of slate was carried out with certain violations, and the material constantly experiences excessive stress. It’s also bad if during installation you used ordinary nails without rubber gaskets to fasten the sheets - then you can’t do without cracks.
  8. Careless transportation and storage. Such defects may not be detected immediately, but they will immediately become noticeable from walking on them on the roof.
  9. Sharp temperature changes. Believe me, any asbestos-cement material does not like this.
  10. Due to disproportionately small holes for screws or nails. Do not forget that metal is characterized by seasonal expansion, and therefore you need to leave a little more space for such fastening (but not so that it becomes numb rainwater). That's why rubber gaskets are needed.

And finally, snow can add new problems. The fact is that the slate roof does not have such smoothness as the metal one, and snow constantly lingers on it. And just a little sunlight is enough to flood all this snow cap from below - as a result, the melted water flows down to the eaves, where it meets a new layer of snow (the cornice is always colder than the roof over the living quarters). Here, the melt water freezes again and, in the form of ice, is already destroying not only slate sheets, but also drainage system. In addition, all this mass, under natural expansion from low temperature, is clogged under the sheets and from there, melting, it falls directly onto the rafters or into the insulation.

Also, often the cause of cracks in slate lies in its incorrect manufacturing technology. And at several stages:

  • During the preparation of the mortar, less cement was added than the factory recipe required (guess why).
  • Gross violations of the production technology of slate sheets (handicraft production).
  • Short asbestos fibers were used in the slate (and this is the manufacturer's decision).
  • Poor quality processing of finished slate sheets (lack of control).
  • Reduction of material opening period (a need 28 days).

And now let's talk about how and how to fix holes and cracks on the slate roof of the house.

How to detect coating defects?

Agree that it is rather difficult to notice new defects or cracks on an outwardly heterogeneous slate roof, while on a smooth seam roof or corrugated board this is easy to do even from a neighboring building. Therefore, pay attention to such alarming signs that your roof needs to be urgently repaired:

The fact is that unnoticed leaks are quite insidious: the rafters are immediately saturated with moisture, the thermal insulation becomes damp and deteriorates, and the ceiling needs repair. Go to the attic if you have such suspicions: if you smell dampness, then there is a problem. And individual mold spots indicate that there is a crack somewhere in the slate, but so far it does not make itself felt, except for small leaks. Check the under roof space of the slate roof also after every downpour.

We put a "diagnosis" on the cracks of the sheets

If the cracks went along the protruding waves of slate, then the bookmarks must be applied both from below and from above.

Cracks in the lower waves require the most difficult decisions. After all, it is here that water will constantly stagnate, and it is rather difficult to achieve the necessary tightness.

But let's look first at the crack itself - a lot depends on this:

  1. A crack that goes along the top wave of slate(it is the easiest to spot), usually does not leak due to the fact that the water under it does not stagnate. This is the most harmless crack, and it is easy to repair it - just bend the galvanized iron and slip it under the slate, and cover the crack itself with a special roofing tape.
  2. A crack that goes along the bottom wave, the most dangerous - here you can not do without leaks. Use sealant, patch and folded sheet.
  3. A crack that went across the slate sheet the most dangerous! And leaks alone are indispensable here - the crack will expand and move on to subsequent waves in the future.

Have you decided on your next renovation? Proceed with caution! Remember that in many countries of the world this roofing is completely prohibited due to harm to health, and therefore, when dismantling old sheets or machining, protect yourself from asbestos fibers. Here's how professional teams do it:

How to fix cracks and holes in slate?

Before applying any patch, it is important to completely clean the repaired surface of debris and moss, and then wash it with a powerful jet of water. But how to close up holes and holes in the slate on the roof available materials and novelties of the construction market:

Method number 1. Cement and sand

Prepare a mixture of one part dry cement and two sifted sand. Fill with water and stir until desired consistency. close up. Let the cracks dry well and paint them in a suitable color.

Method number 2. Butyl rubber tape

A special butyl rubber tape is also good as a patch for holes and cracks. What is good, its surface is made of non-woven material, so that it is good to paint such a patch in the desired shade. And it's easy to work with:

  • Step 1. Degrease the repaired area of ​​the slate sheet with gasoline.
  • Step 2 Remove the protective strip from the tape and stick it to the damaged area.
  • Step 3. Paint in color so that your roof does not look "patched".

Ready-made butyl patches are also used for repairs:

To seal cracks in slate, sickle is also used - a tape that gives strength to the putty joint of sheets. To do this, a layer of bitumen is first applied to the crack, then a sickle is applied to it, and then everything is again smeared with bitumen.

Or use the more expensive one modern version tapes that are designed specifically for the repair of such roofs:

Method number 3. hot bitumen

Prepare bituminous mastic at the stake is not difficult:

  1. We kindle a fire, put two bricks on the sides.
  2. We take an old bucket, put a piece of bitumen in it.
  3. We put the bucket on the fire and stir gently so that nothing catches fire.

If you work in sub-zero temperatures, add 10% waste to the bitumen to give it elasticity and avoid cracking the mastic. Especially if you process the edges of slate sheets:

Hot bitumen is also suitable for sealing small cracks:

But remember that any putty gives only a temporary effect. The problem with using traditional slate putties is that this roofing material little pliable for expansion, while putties usually have a completely different coefficient. That's why after a few cycles of temperature fluctuations, leakage problems return again. And sometimes it is much easier and more reliable to simply replace the defective sheet.

Method number 4. Putty from asbestos, cement and PVA

First we take asbestos in ready-made. If you didn’t manage to get one, just grate it from a piece of slate. Be sure to protect your respiratory tract during this work!

So, to prepare the mixture, you will need to mix 2 parts of cement, 3 asbestos and a liquid solution of PVA glue and water, taken equally. Stir the mixture until it thickens like sour cream. If you cleaned part of the slate before repairing, wait until it dries completely. Next, apply the prepared mixture, treat with a solution of PVA and water (now the ratio is 1: 3) and apply 2 more layers of the mixture.

Method number 5. Finished putties

For the repair of such a roof, ready-made mixtures that include waterproofing materials are well suited. You need to work with them like this:

  • Step 1. We clean the repaired surface well.
  • Step 2. Degrease the area with a solvent or acetone, dry well.
  • Step 3. We prime the surface with a repair mixture, only diluted to a liquid state.
  • Step 4. We apply the mixture with a special gun or spatula.
  • Step 5. After 6 hours, cover with fiberglass and put a new layer of the mixture.

Please note that it is necessary to carry out such repairs on a slate roof in dry and cloudy weather so that the necessary components in the mixtures dry slowly.

Method number 6. Foam and epoxy

Close up cracks and holes in slate also liquid foam, but for this you will have to purchase a whole bottle. Practiced among home craftsmen and the so-called "three-layer" method:

  • Step 1. We clean and degrease the area.
  • Step 2. We close the crack with mounting foam.
  • Step 3. Dry or just leave for a day.
  • Step 4. Apply sealant.
  • Step 5. Cover it all with resin.

Epoxy resin is also suitable for repairing a slate roof, which is much less destroyed under ultraviolet rays than polystyrene.

This is an expensive but reliable method to cope with small problems, although it is inconvenient to use it on an inclined plane. So, if the slate sheet is split along its entire length, fasten the wavy joints with epoxy glue. But first, fix them together from below with mounting tape, and only then fill the gap from above.

Method number 7. Tin patch

This method is suitable for repairing large holes and cracks in a slate roof. So, step by step:

  • Step 1. Cut out a patch from tin, roll it into a tube.
  • Step 2. We push it into the hole so that a hole can be made in the middle of the patch.
  • Step 3. Insert a bolt with a gasket into the hole and press it.
  • Step 4 Fill gaps with building sealant.

The repair of a slate roof must be approached seriously. If the patch will allow even a little water to pass further, the rafters will eventually become completely unusable.

Method number 8. Drying oil with chalk

This is one of the most proven folk methods. So, we clean the cracks, carefully cover them up, and after drying, paint with oil paint. That's all!

Method number 9. Moisture resistant glue

  • Step 1. We wash the sheets well with ordinary water, three of them with a stiff brush.
  • Step 2. We are waiting for the slate to dry and seal each hole with a piece of dense fabric so that its edges extend beyond the hole by about 3-4 cm. To do this, we impregnate the patch with moisture-resistant glue.
  • Step 3. On top of the patch, once again apply a layer of glue (Emalit).
  • Step 4 Turn over the damaged sheet and fill the hole with concrete.
  • Step 5. Once the mortar has set, glue another patch.
  • Step 6 At the end of the crack, we drill a hole and seal it with an elastic sealant.

Method number 10. Aluminium foil

Ordinary aluminum foil will also help to cope with cracks:

  • Step 1. Remove the old fasteners from the sheet.
  • Step 2. Round off the corners of the patch.
  • Step 3. Fasten the foil and press it with a self-tapping screw.
  • Step 4 If the slate on your roof is colored, repaint the patch in the same color.

In extreme cases, it is easier to replace any section of a slate roof than to repair it. Then cut out the necessary elements from the new sheets:

Often, the ridge of a slate roof also becomes unusable, which is not difficult to replace with metal or wood:

How to protect the slate from further destruction?

The situation is worse if the roof began to burst in different places. This is usually indicative of installation errors in due course, and the usual repair of the slate on the roof will only give a temporary effect. It is urgent to stop the destruction process:

  • Method number 1. To prevent cracking, temporarily place a strip of cloth soaked in paint over the crack.
  • Method number 2. Also, so that the crack does not go further, a hole is drilled in it and fixed with a self-tapping screw. Moreover, such a hole must be sealed with an additional roofing sealant, which will tighten, like rubber, the edges of the hole.

But, if in the next decade you are not going to change the entire roof, then approach the issue of repair more globally:

Or like this:

That's all! Choose the method for which you already have materials and you know how to work with them.

Being the most durable roofing material, slate has been used to cover buildings since the middle of the last century. But in spite of all his positive traits, time and mechanical influences can cause unexpected damage. And in this case, it is very important to know how to repair a crack in the slate, or to eliminate the resulting chip.

1 Crack in the slate - is it worth sounding the alarm?

In order to avoid the need to completely replace the sheet, which is not an easy task, you can use various methods to correct the defect that has arisen. And, despite the requirement for certain skills, it is easier than replacing the entire sheet.

Most often, damage occurs due to the "aging" of the slate. But besides this, there are other reasons:

  • the kit included a sheet created in violation of manufacturing technology;
  • poor quality of processing the sheet itself at the final stage;
  • low-quality asbestos material;
  • error in choosing the angle of inclination when laying it;
  • violation of the order of laying sheets, which caused additional stress;
  • special nails were not used to fasten the slate;
  • the crack appeared during the drilling of slate or its cutting;
  • hard material on the roof as a result of gusts of wind or pranks of children.

Often roofing manufacturers do not comply with curing time requirements. It is determined by the standards in 28 days. But, as always, profit becomes a priority. Many reduce this period by sending unseasoned sheets for sale. This is the main reason for the increased fragility of slate. But the experience of roofing masters is the source of many recipes for repairing cracks and chips in slate.

Our advice and knowledge will help you choose the most suitable method. It is important to ensure that the problem is resolved as quickly as possible. Especially when the weather conditions do not allow for a long time to think.

2 Slate crack repair - ways to restore damaged sheets

One of the options when sealing cracks in slate requires a repair mixture, which is prepared independently. It consists of: asbestos, cement, water, PVA glue. The preparation of the mixture should be carried out in compliance with the ratio of asbestos and cement - 3 to 1, water and PVA glue are added in equal amounts to obtain the consistency of a homogeneous sour cream. It is very important to pay attention to the mixing process - the formation of lumps should not be allowed.

Before applying the solution, the crack must be prepared. If this is just a crack, then a sickle (fiberglass tape) is fixed on top of it, along the entire length. If there is significant damage or a hole, then it must be filled, for example, with raw rubber. On the damaged surface, you can now apply the resulting solution, trying to do it evenly. And it will be very good if the mixture significantly covers the damage zone.

Another method is based on the use of special aluminum foil. It is necessary to first apply the adhesive of the universal group to the foil, and then apply it to the damaged area. This provides a very strong connection between the foil and the roof, preventing water from entering. There is another way to cover up cracks in slate. For these purposes, silicone paste must be available. The pre-damaged area of ​​the slate must be cleaned, degreased and dried. The paste will stick well only on such an area.

The fourth option, demonstrating the possibility of how to close a crack in slate, is the proven method of using butyl rubber tape. The self-adhesive tape has high adhesive qualities. It is able to stick very firmly to almost any material - wood, plastic, iron, glass, film. When gluing a crack on asbestos slate, a high-quality overlay is obtained that does not allow water to enter, withstands any climatic influences, temperature changes. This tape is not afraid of dirt, dust or ultraviolet.

Based on the described options, you first need to decide what is best to cover up the cracks in the slate, or use tapes to get the most efficiency from the method used and lower costs for this repair.

3 How to close a crack in slate - basic rules

The first step in the slate repair process is always the preparation of the repair area. In no case should you start work if this stage has not been completed. Each material, and especially the repair mortar, is most effective at the very beginning after its preparation. Any delay leading to its untimely use could be a practical failure. The solution will lose its properties and will not provide high-quality protection.

The trash is removed first. The site of damage is thoroughly washed and degreased. Here you can use gasoline. When working with asbestos solution, it is necessary to use a respirator. The mixture does not need to be prepared in in large numbers. Its properties are lost with prolonged non-use. It is enough to knead in small volumes, covering the crack zone gradually. The solution itself is poured into the crack sequentially, twice. It is required to achieve a layer thickness of at least two millimeters.

If the damage is significant - the split occurred along the entire length of the sheet, you can use epoxy resin to glue parts of the sheet. Previously, an adhesive tape is used for connection from the inside. You can use a fixed galvanized patch - silicone or bituminous mastic is used in the junction area. This option is often used if the crack has passed over the entire surface of the sheet, starting from the site of the previous repair. To do this, the old fasteners are removed. After repairing the sheet, both parts of the slate are attached in new places.

Among the various repair methods, there is a method in which polyurethane foam is used. In the case of large holes, it is blown into the damaged area, observing the rules for using such material. And here it is necessary to fulfill one condition - when the foam has frozen, it must be cut along the contour of the sheet. On the outside of the slate along the damage, the foam itself must be protected by the sealant. According to it, additional processing is carried out with roofing mastic, which is intended for waterproofing roofs.

The repair of a crack that has damaged a slate sheet will be successful if high adhesion of materials is ensured - it is better to prime the damaged area with PVA glue.

And one more very important rule. In case of severe damage, for example, partial destruction of the sheet, the formation of significant and even several holes, the only solution is to completely replace such a slate sheet. Repair will not provide the slate with the required properties, will not be able to protect it from further damage and soaking. And this, in turn, will lead to leakage. In addition, the result will be meaningless financial and labor costs.

Despite the fact that the roofing of asbestos-cement sheets is durable after decades, external atmospheric and climatic factors have an impact on the material. Something has to be replaced, something to patch up, somewhere to block. This is where the application of knowledge in the field of construction is required, and if you know how to repair a crack in the slate on the roof, then such work will not seem difficult.

Cosmetic repairs will help extend the operational life of the roof for up to 10 years. Therefore, the topic is especially relevant. In the past, roofing was completed using oil paints and fabric strips. This technique was not famous for its special effect, and the state of the overlap improved for only a couple of years. Today at free access modern materials making the process of eliminating cracks and chips on the roof more efficient.

Simple house roof renovation

Roof leakage indicates damage to the integrity of the material. To get rid of this problem, you can use one of the effective ways. Any of them is easily applicable in practice and is not difficult, but here it is important to know how to close a crack in the slate on the roof. In 90% of cases, patching or sealing of the affected area of ​​the roof will be required.

Familiarize yourself with the options for action in the event of a roof leak, the easiest and fast method elimination of leaks, the method of patching slate. It is important to talk about such details in advance.

The most common technology for the restoration of asbestos-cement damaged sheets is the use of asbestos paste.

How to work with the material: application features

Using asbestos paste to seal cracks, take care of the preliminary dismantling of the damaged roof fragment and lower it to the ground.

What is required to prepare the composition

The mixture consists of two components: asbestos and cement. This pasta is easy to make at home.

Components:

  • asbestos - 3 parts;
  • cement - 1 part;
  • water - 0.5 parts;
  • dispersion polyvinyl acetate adhesive - 0.5 parts.

Water and glue can be added as needed until the paste reaches a creamy consistency.

For cooking:

  • prepare a separate container;
  • pour out the required amount of asbestos and cement (proportion 3: 1);
  • mix the ingredients thoroughly;
  • add water and dispersion adhesive;
  • Stir the paste until a smooth creamy consistency is achieved.

How to work with asbestos mixture

Knowing how to close a crack in the slate on the roof, you can get to work. Try to use cooked pasta immediately. During storage, the composition loses its properties. Therefore, prepare exactly as much grout as is needed to repair the roof of the house.

preparatory moment

Before sealing the roof, prepare the damaged area:

  • clean the slate from debris;
  • thoroughly rinse the place of the broken slate and degrease it. Gasoline is suitable for such purposes;
  • if an ordinary crack has formed on the surface, stick a fiberglass tape (sickle) along the entire length, extending it by 5 cm in each direction from the crack (vertically);
  • fill the voids of the crack with raw rubber or caulk them. The fibrous material can be further treated with a hydrophobic composition.

Application of asbestos cement paste

The composition is applied to the damaged area gradually, evenly distributing each of the layers over the surface. In this case, the total thickness of the applied paste must reach at least 2 mm. After the patch has dried, the seam must be treated with sandpaper.

When carrying out restoration, try to cover up so that the coverage area extends beyond the crack. Having repaired broken slate sheets, you can not worry that the roof will leak for the next 8-10 years.

Use of foil

Asbestos paste is not the only option for treating roof damage. If you do not know how to repair a crack in the slate on the roof, use foil instead of paste, on which a little universal glue is applied and applied to the damaged area from the wrong side. The tight fit of the patch is ensured by rounding the corners, so they bend less. The connection of the foil with the reconstructed surface is strong due to the universal adhesive composition used and reliably protects the interior of the attic from the penetration of water and moisture.

If you need to seal up that part of the roof where the fastener passes, then close the crack with foil and drill a hole for the fasteners in another part of the sheet.

After repair, the removed slate sheet is mounted in place. Do not forget about the use of special rubber gaskets for nails to protect the corrugated board from damage during installation. After completing the reconstruction, disguise the patch to match the tone of the roofing material. At this stage, work is carried out in dry weather, and when applying paint, a brush or roller is used. It is better to apply several layers, starting to re-paint only after the first has completely dried.

Some of the methods do not involve the dismantling of damaged products in the place where the slate burst. How to close the crack, if you need to go upstairs, read on. Such work is done directly on the roof, and for this it is vital to provide insurance.

Silicone paste for roof repair

Often, silicone paste is used to repair the roof. The tool is characterized by increased adhesion to materials made from asbestos cement.

Getting started, the damaged area is prepared: cleaned of dust and small dirt crumbs, using a brush for cleaning metal products. To do this, use acetone or a special solvent.

Before sealing the crack, it is filled with crushed asbestos chips, which are then filled with silicone glue for slate. Such a restoration is not difficult to carry out, and the whole process takes a maximum of a day and ends at the stage of tinting the treated area under the general style of the roof. At the same time, coloring plays not only an aesthetic role, but also gives the connection additional reliability. Coloring in this case is simply necessary. The top layer allows you to fix a multi-layer patch, because asbestos cement sheets themselves porous.

Repairing damage with mastic

It is important to remember that at the joints, slate sheets are processed with mastic with a special reinforcing filler of a wavy structure.

Bitumen is melted in a separate container, after grinding. Foam and impurities formed in the process are removed. The melting process takes place at temperatures above 200°C until the bitumen is completely dehydrated. The grout consists not only of bitumen, a filler is added to the composition, which is preheated to a temperature of 110 ° C.

Hot mastic, using a spatula or other suitable tool, is applied to the surface prepared for repair.

Sometimes a kind of rubber paint for slate is used to restore damaged sheets. The tool has increased adhesive and strength properties. This method of slate restoration is gaining popularity.

How to use mounting foam to seal cracks in slate

Applying for recovery mounting foam, slate is pre-cleaned and degreased. Foam is blown into the resulting crack, but some free space is left for the sealant, which, after the foam has hardened, is squeezed out in a dense layer over the foam. A bituminous mastic is applied over the patch that has formed, which helps to seal the crack in the slate and protect the interior of the attic from atmospheric precipitation.

Now you understand all the complexities of slate repair. How to repair holes and cracks - you know, you understand the details, but this is the main thing when carrying out restoration work with asbestos-cement sheets.

Slate - asbestos cement roofing material a wide range applications that have been in demand for many decades.

Even with the appearance of new analogues on the roofing market, slate remains the most popular among them.

Slate properties

Slate was invented over a hundred years ago. It is used in regions with both hot and cold climates. The service life of slate reaches 50 years, but in most cases 20-30 years.

Atmospheric precipitation practically does not affect the operation of slate.

One of the main properties of a slate roof is its small thermal conductivity. When the roof of the house is heated by the sun's rays, the climate under the slate remains quite comfortable. And in the cold season, has good thermal insulation.

Another very important advantage of slate is good sound insulation. Compared to metal roofs, it perfectly soundproofs the blows of hail, rain, and therefore you will practically not receive discomfort from showers and thunderstorms.

Slate - heavy and brittle material and this is its main disadvantage.

Material disadvantages

Reasons for the destruction of slate sheets

Asbestos cement slate is a rather fragile material, and it is often

Often problems arise precisely because of incorrect fasteners, therefore during installation, it is very important to follow the installation technique. Do not pierce the sheets with nails, and before installation, you need to drill it in the attachment points.

When the lathing is done correctly - there is no sagging and the step of the lathing is observed, then the roof will serve for many years.

During operation, the slate is constantly exposed to negative factors. environment, which affects the condition of the roof is not the best way.

NOTE!

The main reasons for the destruction of slate during operation are sagging from heavy snow masses. Also a negative factor is stagnant rainwater falling on the roof of the branch.

As a consequence of this microcracks appear, which further lead to the destruction of the coating. Also, slate can be spoiled by mosses growing on it, lichens, they release acid-containing substances that destroy it.

How to detect coating defects in a timely manner

Leaks are very undesirable consequences of a violation of the roofing system. They appear from various kinds of damage:

  • biological;
  • Mechanical influences;
  • weather conditions.

To prevent roof leaks, from time to time it is necessary to inspect the slate. Common Defects slate roofs are chips on the surface and edges of slate sheets. Most often, the causes of repair arise due to the "aging" of the material.

Slate repair - how to fix a crack in the slate on the roof

If you still need to repair the slate, there is a crack or gap, there are many ways to repair.

So, how to fix a hole in the slate on the roof:

  • First way: to seal cracks, you can make a special solution, it contains asbestos, cement, water and PVA glue. Water and glue according to 1:1, asbestos and cement 3:1. Stir to a paste-like consistency and apply to the crack (the crack should first be caulked).
  • Second way: Can be used mounting foam for blowing cracks. After the foam hardens, the excess foam must be cut off, and on top of the cut, smear with sealant and a layer of roofing mastic for waterproofing.
  • Third way: Aluminium foil often used as a material for sealing cracks in slate. The foil is folded in several layers, smeared with roofing sealant and applied to the area that is damaged.
  • Fourth way: Can be used special silicone paste but it is very important that the surface is clean, dry and free of grease. After application, it is necessary to wait for complete drying. Only under such conditions will there be a waterproofing effect from the application.
  • Fifth way: Available for sale ready mix putty, which are also used to cover cracks and seams and it costs less than silicone paste. To do this, it is enough to buy a ready-made composition. The surface must also be clean, dry and free of grease. Before application, the surface to be repaired must be primed with a conventional repair primer. After application, wait about six hours for drying, and if necessary, apply several more layers of the mixture.
  • Sixth way: Applies also butyl rubber tape. It is easy to work with, because its surface is made of non-woven material, which is good if you need to stain in the future. It sticks to almost any kind of surface, withstands temperature extremes well and endures the negative effects of weather conditions.
  • Seventh way: Seam sealing method hot bitumen. Bitumen is very easy to use. For putty, you need to take a piece of bitumen, heat it over a fire in a special bowl, stirring gently to 160 degrees. In this state, it can be poured into the cracks.
  • Eighth way: Of the proven folk methods, the best is chalk with drying oil. We mix, cover the cracks, after drying, paint with oil paint. Ready!

Repair with rubber tape

Repair with bituminous mastic

If all the above methods did not help you, or the area in need of repair is too large, you need to think about replacing the sheet or the entire roofing material.

To replace one sheet of slate, you must:

  1. Unscrew fasteners that hold the sheet.
  2. At first we take out the damaged sheet from under the neighboring sheet, under it we put a bar that will temporarily hold it.
  3. Further attaching a new sheet into specially prepared holes.

When replacing one or more sheets does not solve the problem, or the slate is too worn out, then the slate coating is completely changed. To increase the strength, abestos-cement slate is painted with oil paint.

Use any oil paint, while it is possible to cover both old sheets and new ones. The paint that covers the slate should be liquid enough to lay down in a thin layer and be well absorbed. If necessary, it can be diluted with a solvent.

For a quality repair, be sure to clean the surface and degrease it. The primer contributes to a good adhesion of the material, so this step should not be neglected. Compliance with these simple tips will help to ensure the durability of the repair.

Do-it-yourself slate repair on the roof on the video:

Everyone has been in a situation where, during normal driving, a stone flies out from under the wheels of a car in front of you. In this case, the windshield of the car is often damaged in the form of cracks. And what then to do if you do not have extra time and money, and this ill-fated, albeit small crack does not give you rest? You are quite capable of coping with this disease on your own and without outside help, without resorting to the services of a car service. Here are 4 simple ways how to seal a crack on the windshield with your own hands.

The first step, of course, is to prepare the cracked glass for repair. To do this, the glass must first be washed with water and detergent, and then wiped dry with a clean cloth. It is very important that there is no water and dust in the place of the crack, since in this case the glue will not set well. After the glass has dried, it is necessary to degrease the surface. We take a synthetic fabric (does not leave lint behind) and moisten it in acetone or solvent. Well, here are 4 easy ways:

1 way. silicone adhesive

This is the easiest way. Glue is applied directly from the tube or with a medical syringe. Fill the cavity slowly and gradually, avoiding air bubbles. We leave the work done for a day until completely dry. Depending on the type of silicone, the repaired area will dry from 12 to 24 hours. For reliability, the former crack can be covered with a thin layer of transparent varnish.

2 way. Styrofoam + acetone + turpentine

What is needed here is already clear. We mix acetone and turpentine (3: 1, that is, there will be three times more acetone) in glass jar. Next, in the resulting solution, you need to crumble the foam into small pieces (the smaller the pieces of foam, the faster the reaction occurs). We mix, wait a bit until the foam dissolves and the mass becomes transparent and viscous. This glue hardens quickly, so you need to do it in small portions and use it immediately after preparation. The resulting adhesive can be applied to the crack with a syringe or a thin brush.

3 way. Clear nail polish

If the crack on the glass is very thin, cover it with colorless nail polish. Such bonding can prevent crack growth and should last for about 3 or more years. Apply a thin layer of varnish on both sides and wait until it dries completely. Lacquer applied on the outside of the window will not be washed away by rain.

4 way. Stationery tape

Best of all, once a crack has formed on the glass, seal it with ordinary stationery tape to protect it from dirt and dust, and also to prevent its growth. It is enough to glue the place of damage on both sides. Of course, such repairs are short-lived, and soon you will have to take more serious measures.

Modern batteries, unlike the old ones, are not subject to such global repairs as replacing plates, etc. In some models, it is not even possible to add water, not to mention something else. I will tell you what can be done if, as a result of an accident or for some other reason, a crack appears in the battery. I will say right away that if all the electrolyte has leaked out and the battery has stood for a month, then most likely it can be thrown away due to plaque on the plates. It is impossible to add electrolyte to the old one; this will most likely damage the battery. Almost all battery cases are made of plastic such as >PE< полиэтилен. Цитата из википедии: “ полиэтилен при room temperature insoluble and does not swell in any of the known solvents.” If you are interested, you can type in the search engine “how to glue polyethylene” and you will understand that any glue disappears immediately. Technologies, of course, do not stand still, maybe they will come up with something. It will also not work to melt a crack with an ordinary soldering iron, as a result it will still flow. The only way to repair it, in my opinion, is welding. A donor can be taken, for example, from a washer reservoir or fender liner marked PE (BUMPER WILL NOT SUIT!). Below is a video of such a repair. When trying to fill the terminal, the case burst. As will be seen, the owner of the battery first tried to melt the crack, then glue it. The ending of the video, for some reason, was cut off, but I think the essence will be clear.

I myself did not believe that a broken plastic shelf from a refrigerator can be stupidly glued together with a thermal gun, and it works fine further. Just glued the seam, and that's it. Although in a good way it was necessary, of course, to take a mesh, even a window one, and “plaster” it on a layer of glue, so that it would be stronger.
Well, of course, you need to look at what kind of plastic, some are glued just disgustingly, and some can be soldered with a hairdryer.

Do-it-yourself plastic bumper repair

Even the most experienced driver cannot be insured against damage to the bumper of your car. If not you, then you. If it is solved through the insurance - good. If the insurance does not roll, then there are two options: trust the professionals (it often happens here too) and lay out not a small amount or Do your own bumper repair.
It all starts with damage assessment. Usually a bumper is not very expensive, especially if you buy a Chinese counterpart. If the bumper has suffered quite seriously, then there can be no question of any restoration of it - it will come out more expensive. Repair work It is advisable to restore a plastic bumper if there is a small crack or cracks, scratches, chips, dents, or if a replacement cannot be found at all.

Before repair, it is desirable to remove the bumper, for convenience. The entire restoration process, up to painting, is conveniently performed on a separate stand.

Procedure

— Remove the damaged bumper;

- Wash it well;

— Remove the paint coating of the damaged area;

- Clean the outer and inner surfaces with a grip of 10-15 mm on the sides of the damage. The layer of paint removed during stripping should be at least 0.2 mm, since the top layer of the surface often changes its properties during operation, which may affect the quality of our repair seam;

- Drill the ends of the cracks (this will prevent their further growth). Here, it is the same as when repairing cracks, chips on the windshield with your own hands;

- To make the actual repair - we will consider the methods below;

- Priming and painting - will be required in most cases.

To repair the bumper with your own hands, you will need a minimum set of tools:

— car hair dryer. This is a special device that does not differ in appearance and principle of operation from a conventional hair dryer. The only difference is that the flow of hot air from such a hair dryer has more high temperature and can soften or melt plastic.

— soldering iron. You can use any soldering iron, preferably more powerful. Rosin and tin are not required, not the case.

— Metal mesh. These are sold in specialized stores. The mesh will allow you to fasten pieces of plastic together. You can use an old air filter.

— Priming. An ordinary spray can of automotive primer is quite suitable. If there is a compressor and a spray gun, then it's even better. Take your pick - it doesn't matter.

— Putty. No matter how perfect you solder the cracks, you still need putty. The exception is if this place is not visible.

— Sandpaper. For grouting putty 40 and 80 numbers, and for grouting soil already 800.

— Any rag. It will be needed when washing the bumper, and when working with a hair dryer, because straightening hot plastic with bare hands is not always comfortable. It's good to use gloves as well.

— Piece of an old bumper. It will be needed in exceptional cases when there is not enough plastic.

It may be advisable to buy a repair kit that includes items such as sandpaper, various retouching paints, and fillers. Such kits are not so expensive and can be cheaper than taking everything separately, since the kits do not use large packaging - why do you need a whole can of primer for a small crack? Also putty, etc.

bumper repair

To begin with, a qualitative inspection is carried out in good lighting. Determine how many cracks, scratches, chips and dents your bumper has. We immediately calculate the amount of mesh, putty and other Supplies. It is best to do this before buying consumables and the missing tool.

Now let's take a closer look at the inside of the bumper. There you need to find extruded (in some cases melted) information about the material of the product. Depending on the type of marking, the following conclusions can be drawn:
type designations PP (PPTV20 and analogues) - the bumper is made of propylene;
mark PUR - polyurethane bumper;
PAG 6 (GF, ABS) - the designation of hard plastics.

But it is not complete list materials from which bumpers for cars are made. You can also find parts made of fiberglass and similar carbons, but they are marked very rarely and the maximum that can be found is the manufacturer's information. But if your bumper is made of hard (thermosetting) plastic or carbon, then repairing plastic bumpers of this type is different from repairing products made from other materials.

Cracks.

If there is a crack on the bumper, then we need a soldering iron and a mesh. Flip the bumper upside down and cut the mesh. It is worth making oblong pieces 2-3 centimeters wide and a crack long in size. Bring the edges of the crack together and solder one end of the mesh. We need to drown it in plastic, but we don’t get carried away much, you can just make a hole. After that, melted plastic should cover the end of the mesh. Further, in this way, we solder the entire crack.

Let's look at the outside of the bumper. If everything is ideal there, then nothing needs to be done. Otherwise, we pass the mesh on the outside. The main thing is to hide the ends of the mesh so that nothing sticks out. When you sharpen the putty with sandpaper, you will regret the protruding mesh hairs.

Small cracks, instead of mesh, can be reinforced with staples from a furniture stapler. The size of the staples should be chosen so that their legs do not pierce through the body. If there are no suitable staples, then you can take others and shorten them to the desired length. Use tweezers when soldering fittings, so you will protect yourself from burns.

We place the staples perpendicular to the seam at a distance of 1-2 cm along the entire length of the fault. Barely emerging cracks and branches are also fused. Otherwise, in the future, from vibration, they will develop into splits. In order to protect the staples from corrosion, completely cover them with heated plastic, pulling it from adjacent areas. After you fuse the bumper on the inside, the front surface should return to its original shape.

If the cracks on the bumper are large or there are fasteners nearby (the places where the bumper is attached to the body), since the nearby surface of the bumper often breaks, it is advisable to tighten the crack with screws before soldering. A fairly simple but very effective method is proposed.

We take a suspension - it’s definitely called a “metal suspension for attaching guides”, there are such in any hardware store. We need it to tighten the crack with screws.

We cut it with a hacksaw or "grinder" as shown in the photo, depending on the type of bumper crack. Usually use parts 1 or 2 - the holes used are shaded in blue. Although it happens that when two cracks converge together, piece of iron No. 3 is used. Below is an example of the location of the plates on a bumper crack.

In the figure - blue shows the working holes for the bolts. We drill holes in the bumper for the screws, put a plate on the back side, insert the screw into the holes and fix the entire structure with nuts.

If you are repairing a bumper for the first time, then be sure to carry out this procedure from the inside (and not the first time, too).

Place a plate over the crack. Through the holes in the plate, drill holes in the bumper with a drill with a diameter of 3.6 to 3.8 mm. Drill so that the drill is closer to the outer edge of the plate hole.
the drilled hole in the bumper must be countersinked so that the screw head "drowns" into the bumper. If there is no countersink, a drill bit with a diameter slightly larger than the diameter of the screw head can be used instead. When countersinking, do not overdo it, do not drill through! But too small a hole is also not necessary. And yet - you can drill manually, just by hand, with a large drill in the hole drilled for the screw, make a couple of turns - and the desired angle for the hat is ready.

We check the quality of soldering. Shake in the place of the crack after drying.

How to fix a barrel, flask, bucket, watering can, canister

If everything is flimsy, then you have to solder it. However, this cannot be allowed, everything should be done for sure. After splicing the crack, the bumper surface should also be degreased and covered with fiberglass, and then with putty.

dents

If the dent turned out without a scratch, that is, the paintwork remained intact, you are very lucky. You can fix it in minutes. This completes the restoration of the bumper. All you need to do is wet a regular rag, turn on the hair dryer and heat the dent from the back. Warm up usually no more than thirty seconds. Then we wind a damp rag on a fist and begin to bend the plastic back. We do everything carefully and without the use of great force. The main thing is not to transfer everything out. You can do several approaches in a break of ten minutes, allowing the plastic to cool.

In the case when, in addition to the dent, there is also a crack, we perform the same actions, but with the expectation of further puttying and painting the surface.

Chips and scratches

You can fight them with sandpaper. We take the largest one (number 40) and start rubbing. It is necessary to sharpen the pits, turning everything into a more or less even surface. The pit, in fact, increases in diameter, but loses in depth. Then we will fill this depth with putty. It is advisable to use body bars, if available, but you can also rub with your palm.

Detailed instructions for removing chips and scratches on a car - for those who need it.

A good result is obtained by using liquid plastic that matches your type of plastic on the bumper. Be sure to consult with the seller, after writing down the type of material of your bumper.
Stick masking tape (it is better to use self-adhesive fiberglass tape) on the front surface of the bumper. On cardboard, mix the adhesive mass and thickener. Apply the resulting mass to the masking tape. This is done to level the surface of the bumper. Next, the masking tape is removed, and the surface is again cleaned and sanded. Liquid plastic is applied to this place. After the plastic has hardened, you need to sand the surface.

Putty

Let's prepare the putty by adding a hardener to it. After that, we will immediately apply dents (if the paintwork is damaged), cracks, scratches or chips to the place. This is done naturally after the above mentioned measures to eliminate breakdowns.

Wait ten minutes before starting work. We take sandpaper number 80. With the help of movements directed to the left and right edges of the bumper, it begins to overwrite the putty. Sooner or later you will come to the desired result. Of course, the geometry of the body should be observed if the breakdown appeared in some not very convenient place. You can make several additional layers of putty to give a more even surface.

We prime

Take a rubber rag, wash the bumper and let it dry. Let's check the result for the last time. If everything suits you, then you can proceed to the primer. We take cans or turn on the compressor. Apply the primer with movements directed, again, to the left and right edges of the bumper. Essentially, you need to draw a horizontal line while spraying.

Let the soil dry completely. After that, you will need to take eight-hundredth sandpaper and wash it thoroughly. This is done with a bottle of water. No matter how local the breakdown was, the entire bumper is completely washed out. It should become matte after drying. And the first layer of soil is completely washed off, leaving only gray dots in the risks and pores on the putty.
We will apply another layer of soil, which we will also wash. Check the flatness of the surface under the lamp. There should be no small pores or scratches. The surface at this stage should be perfectly flat.

Now the bumper is completely ready for painting. We advise you to paint everything as soon as possible.

Repair of plastic bumpers made of thermosetting plastics and fiberglass

On the one hand, this method will not require great skills and abilities from you, but on the other hand, it is necessary to follow all the instructions exactly. Only in this case, you can achieve a good result.

The procedure for carrying out repairs:

    we combine the cracked parts, fix them with any quick-drying glue;

    preparing epoxy resin for further use;

    take a brush and coat the area of ​​the crack ranging from 5 cm wide from the inside of the bumper;

    we impregnate the fiberglass mat with epoxy resin and lay it on the prepared area. In the absence of such material, a mesh used to seal drywall joints may be suitable. In the latter case, you will have to apply another layer of epoxy.

Note that in this procedure the fiberglass must be repeatedly applied layer by layer so that the approximate thickness of the bonded patch matches the thickness of the bumper in that area. Front side the product remains unglued. The putty used to hide solder marks and other irregularities should be designed specifically for plastic in any case. Next, paint the finished bumper and screw it into place. If you believe the statistics and try out the technique in practice, then in subsequent operation, if cracks appear on it, then in some other place, but definitely not in the place of the seam we sealed.

In any case, you should not forget that the bumper is, first of all, the face of the car and requires proper care and timely repair. And it will be self repair or bumper repair in a car service - it's up to you.

I myself have not tried to seal plastic buckets, but I have seen how it is done. 5. The neck is glued to the bath with hot glue. The edges of the holes are slightly trimmed with a larger diameter drill, there should be no burrs! 4. In the intended circle, we drill 5-7 drain holes with a diameter of 4-5 millimeters.

ATTENTION! Washcloths and sponges need to be changed quite often, especially if they have lost their integrity and started to crumble. Please note: You can bathe a child in a large common bath only after pre-treating its surface with soda, baby soap or special detergents. Suction cup accessories must be attached before filling the tub with water.

How to seal a plastic container?(+)Yesterday

Water intrusion and detergents reduces the reliability of fixation.

This is steel structure, adjustable in height to which the bath is installed.

In the design of the bath, the factor of its stability is important.

With this posture, the passage of gases is facilitated and colic pains are more easily tolerated. The product meets all safety and hygiene requirements.

Microban is not released into the water and does not lose its properties over time.

The material of the product contains the additive Microban, which disinfects the water when bathing.

If the bath is stationary, then there should be anti-slip pads on the legs. The accessory provides the baby with soft support and prevents it from slipping. The sponge shape for bathing has a profile corresponding to the anatomical contours of the child. In its form, stops are provided between the legs and under the armpits. The anatomic slide is attached to the tub with suction cups. A hanging hammock made of fine mesh is hung over the bottom of the bath with hooks.

It is a removable stand that fixes the position of the child and allows you to make bathing safe and convenient.

What to consider when choosing a bath for a newborn

The anatomic bath has a built-in slide-support inside, following the contours of the child's body, so when bathing, he feels more confident. Armed with knowledge about the types and properties of baby baths and additional items to them, you will do right choice at the time of buying. For faster falling asleep, it is recommended to do a general massage for the baby, a video tutorial can be viewed in this publication.

This allows you to fix the baby in a comfortable position.

Very comfortable for newborns.

Increases convenience built-in drain. It allows you to quickly and easily change the water during bathing without disturbing the child.

The bath should not be too small so that the baby can use it for at least six months.

It is strange that almost all the accessories are mentioned here, but they forgot about swimming circles - this is about bathing in the bathroom. And when the baby grows up, you can bathe him in a spacious common bath, and leave the nursery for future offspring. Swimming hill.

Therefore, everything is available.

In some models, the stops are adjustable to match the height of the child. After use, it folds up compactly. Buying these items separately will cost less. But you can become the owner of things that you personally do not need.

Plastic buckets, canisters and tanks - things on suburban area necessary. Often, in the conditions of a summer residence, it is not possible to change an old bursting plastic container for a new product, but, if desired, it can always be repaired. How this can be done is described below.

If the bottom of a plastic bucket has burst, then it is useless to try to seal it. No glue can withstand the long-term pressure of the liquid poured into the container, and over time, the crack on the plastic will definitely open.

It is much more reliable to repair a broken bucket by sealing a crack in it with another suitable piece of plastic.

For this you will need:
large and powerful soldering iron;
plastic tape, which, for example, can be cut out of an unnecessary PET bottle, or a plastic tie;
any detergent.


It is necessary to solder the crack both inside the bucket and outside, and it is recommended to start from the inside, since there the edges of the crack can be superimposed on each other quite tightly, resting them against the surface on which the bucket stands.


If you start work from the outside of the crack, then its edges will spring, fall through and it will be difficult to impose them tightly on each other.


However, for ease of perception, let's consider, after all, how a crack is sealed on a plastic bucket from its outer side, bearing in mind that it is already closed inside the container.

So, in order to solder a plastic bucket:
1. Its surface around the crack is thoroughly washed and degreased.


2. Turn on the soldering iron, wait for it to warm up and with smooth movements to the right and left drive its tip along the crack, without pressing on the plastic so as not to burn it. Thus, melting the plastic at the edges of the crack, the tip of the soldering iron passes along its entire length.


3. Sequentially lay the plastic tape on the crack, starting from a point slightly further than its beginning. At the same time, the tape is heated with a soldering iron so that the melted plastic fills the crack cavities, that is, figuratively speaking, it is soldered.



4. After soldering, the cracks get a seam, which is additionally smoothed out with a hot soldering iron, moving its tip along this kind of “welded” line.


This is how easy and without any special tricks you can solder a crack on a plastic bucket or any other container made of plastic. Inside the bucket, the seam is made using the same technology.


It remains only to check whether it leaks after repair.
