Ceiling plinth is a decorative element that completes the decoration of walls and ceilings. It is glued at the junction between the walls and the ceiling with a special glue, while the corners, both internal and external, usually cause the greatest difficulty. How to properly cut a corner on a ceiling plinth so that there are no cracks or dents? This question must have been asked by everyone who has ever tried to glue ceiling plinth with your own hands.

Varieties of ceiling plinth

Ceiling plinth - otherwise it is called a fillet - can be made of different materials: wood, plastic, polyurethane, polystyrene foam or polyvinyl chloride. In addition, they differ in width and relief shape - it can be simple or figured. A fillet of a simple shape is easy to join in the corners without special fittings; for a wide plinth with stucco, it is better not to spare money and buy special corner elements - inner and outer corners made of the same material. A plinth made of wood and polyurethane is cut with a metal file or a strong sharp knife. Polystyrene and PVC skirting boards are easily cut with an ordinary clerical knife; thanks to a thin blade, it does not jam this fragile material.

How to cut a skirting board for a right angle

Most convenient way, which practically excludes the appearance of inconsistencies - is to use . This device is a U-shaped template with slots in the side walls, made at different angles. The plinth is marked in place, noting its maximum length along the ceiling for external corners and along the walls for internal ones. The plinth is laid in a miter box, leveled and cut off at an angle of 45 degrees.

In the absence of a miter box, you can make a template from cardboard or thick paper by drawing lines on it at an angle of 45 degrees using a protractor. The fillet is applied parallel to the edge of the sheet to the marking lines and cut along the ruler with a sharp knife.

If on one segment of the plinth it is necessary to cut off the corner from both sides at once, then it is recommended to start with a more difficult one - an external or uneven corner.

What to do if the inner corner is not straight

The walls in our homes are not always perfect and the angle can be more or less than 90 degrees. In this case, the standard template will not work, and it is better to use markup in place. To do this, you need a hard pencil - it leaves less marks on the ceiling.

The plinth is applied alternately to each of the walls forming an angle, and a line is drawn along its edge on the ceiling. At the intersection of the lines on the baseboards make a mark. Connect it to the bottom edge of the plinth at an angle and cut off the corner with a knife using a ruler. Skirting boards cut in this way lie flat in any corner.

Fillet with stucco is difficult to join in the corners without the use of special corners, but if you could not find the fittings for the relief plinth, you should not despair - using the above methods, you can correctly cut the corner on the ceiling plinth of any shape. It is better to join the plinth in a place with the most protruding stucco elements so that the overall pattern is not disturbed, and the joint should be carefully glued. In this case, the fillets will look neat and fit perfectly into the design.

During installation floor plinth the most difficult task is finishing the corner sections. Skirting strips will be cut into separate elements according to the perimeter of the room. Experts recommend that you first draw a visual installation diagram on paper, paint all the dimensions, and also schematically depict how to make the corners of the floor plinth. With such a hint at hand, finishing work will move much faster.

How to make the inner corner of the floor plinth

Although the rooms are usually a regular rectangle, their corners may not correspond to 90º. As a rule, developers and repairers can only dream of ideal angular convergence of walls.

How to cut the corners of the floor plinth, if you are still lucky, and your apartment has the right angles, then in order to cut the plinth strips, you need to follow these steps:

• the plinth blank must be placed in the miter box (a special construction tool for cutting planks at a certain angle);

The miter box itself (good) is possible. Before ordering, make sure that the width of your skirting board matches the maximum width of the miter box!

• on the side panel of the tool we look for a mark of 45º, insert a hacksaw into the corresponding groove, saw off the excess part of the workpiece;
• further, the cut edge is carefully processed with sandpaper.

Important! When cutting a plinth strip, it is necessary to take into account its location (placement side). It is recommended to cut with some increase, which will make it possible to further fit the skirting board as tightly as possible. If a wooden plinth is used, the joint is additionally treated with a special putty for painting.

What to do if the angle of the converging walls is uneven?

Helps in this situation gypsum plaster and a wide ribbon-serpyanka.

• At the junction of adjacent walls, approximately 10 cm in each direction is applied a small amount of plaster mortar.
• Next, a reinforcing tape is applied to the corner, gently pressed down with a wooden bar.

• The corner is given the correct shape, excess mortar is removed with a spatula.

Important! You need to work with a spatula very carefully so as not to disturb the position of the sickle tape, but also not slowly so that the plaster does not dry out

How to join the outer corners of the floor plinth

When the outside corners of the room are 90º, the procedure for cutting the skirting board is the same as for inside corner joints. It is important when cutting to remember the future side of the plank placement. The ends of the joints of plastic plinths are closed with special plugs. If the cutting of the planks was not done very well, you can correct such a defect with mastic, and then cover it with a plug.

How to join the corners of the floor plinth if they do not have 90º:

• first we apply the skirting board to the first wall;
• draw with a pencil (marker) all the borders;
• we perform similar actions with the second plinth attached to another wall;
• when marking, you should get a rhombus, as in the situation with the internal corner connection, only it will be located outside, respectively, the diagonal is the cutting line of the blanks;
• after cutting, we clean the ends of the planks with sandpaper;
• then we install the plinth, cover the corner joints with a plug (for plastic products). The joints of wooden skirting boards are covered with putty for painting.

After completing the fastening of the plinth strips in the corner sections, they can be finally fixed around the entire perimeter of the room using self-tapping screws, liquid nails, finishing nails or a special adhesive.

Docking plinth at non-standard angles

If you need to finish rounded corner, then the skirting board must be cut into 4-5 separate parts, and special plugs must be used to connect them. Fixing is done with putty or a special adhesive composition.

How to saw down the corners of the plinth of the floor inner-outer corner:

• we apply the first half of the plank to the wall, draw its border with a pencil (marker) on the basis of the floor;
• then we apply the next half of the plank, draw two points: the first is the intersection with the border of the previous plank, the second is with the wall;
• then we connect these points together, perform a cut;
• the ends of the cuts of plastic samples are closed with plugs, the wooden ones are pre-cleaned, then smeared with putty.

How to cut a corner of a floor plinth without a miter box

Interior corner trim

• a profile is placed on the installation site, it must be rested against the adjacent wall;
• a control line is drawn on the sexual basis with a pencil (marker);
• similar actions are performed near another wall;
• the intersection point of two control segments is the lower cut, the junction in the corner is the upper cut.

Outside corner finishing

• in this case, similar actions are performed, only the profile is displayed around the corner of the converging walls;
• where the control segments intersect - the lower cut, the upper cut - the corner face.

Important! For edging the plinth, you must try to hold the hacksaw when cutting at 45º.

Styrofoam ceiling moldings are a great way to decorate the joints of walls and ceilings, regardless of the choice of finishing materials. How to properly cut ceiling skirting boards in the corners of a room? How and on what to stick it to the walls and ceiling? Let's figure it out.

Docking corners is the main problem in skirting board stickers.

How the plinth fits in the corners

In general, there are only two main scenarios.

decorative corners

Special decorative corners are used - external and internal.

What are the advantages and disadvantages of the method?

• This way of docking is as simple as possible. The corner is glued to the wall; adjacent skirting boards are glued to it and to the adjacent section of the wall. No hassle with fitting.

Yes, the plinth is also cut to length here; however, cutting at right angles is not difficult. It is enough to put the plinth on the corner of the table and cut off exactly along its edge (see).

Tip: The best tool for cutting skirting boards is a utility knife. He, unlike all varieties of hacksaws, does not crumble the material.

• However, alas, corners that are suitable in width and pattern are often very problematic to find. Simply due to the limited range of products of one manufacturer from a particular seller (see).
• In addition, the corners allow the plinth to be joined only at right angles. In complex rooms, angles are often not equal to 90 degrees.

Decorative corners are the simplest solution. But it won't always help.

Trimming planks

This docking method is more versatile: no Additional materials, in addition to the plinth; docking is possible at an arbitrary angle. The essence of the method is reduced to the point of trimming the plinth strips in the corners so that there is no gap between them, or at least it is minimal.

With a knife in hand

So, how to properly cut ceiling skirting boards?

Scenario 1: right angle

Let's start with a simpler case. How to cut ceiling skirting boards so that they meet at a right angle?

Obviously, the seam will look best if the seam divides the corner exactly in half. Thus, we need to cut off each of the planks that we connect at a strictly 45 degree angle (see).

The best tool for this operation is a miter box. This simple carpentry fixture is a tray, the walls of which are cut at several fixed angles. Including under the one we need.

• We lay the plinth in the miter box in such a way that the pads for the sticker lie flat against its bottom and wall.
• We cut it off, using the cut we need as a guide.

If the miter box is not at hand, it is easy to make it yourself, using smooth planks or strips of thick plywood as material. The slots in the walls are marked with a square or a protractor.

The miter box is a tool that is easy to make yourself.

Scenario 2: arbitrary angle or right angle without miter box

How to cut the plinth in this case? A miter box will not help in case of an oblique or obtuse angle; and often it makes no sense to buy or make this instrument for the sake of a small room.

Take as an example the fit of the inner corner. Of the tools, we only need a pencil and the same clerical knife. The edge of the table will serve us as a support when trimming the edge of the plinth.

Then again alternately apply both planks of the plinth to the ceiling and mark the intersection point on them.

All that remains to be done is to correctly draw a line from the outer lower corner to the inner upper corner and cut the plinth along it. The easiest way to do this is by placing the baseboard on the edge of the table and aligning both points connected by the cut with its edge. Then strictly vertically cut off the bar along the edge of the table.

Sticker

The operation itself is extremely simple; however, as elsewhere, there are a number of subtleties.

Tip: acrylic putty at the same time will hide the gaps between the skirting boards and the wall, gaps in the corners and other flaws.

• It is optimal to glue the plinth not on top of the wallpaper, but on a plastered surface. The plaster is primed with a primer: this way the plinth will hold much more reliably.
• When using synthetic universal biting, the main problem is that before the glue hardens, the plinth slides or falls.

The solution may be very simple. After applying glue to the edges of the skirting board, press it into place and immediately tear it off. After waiting about a minute, press again, finally. The thickened adhesive will hold the foam securely..

• Be sure to glue the skirting boards together.
• Ceiling skirting can be used with stretch ceiling; however, in this case, it is only glued to the wall. There is a minimum gap between the top edge and the canvas. In this case, the joints of the plinth in the corners should be additionally reinforced with match pins.

• The offset of the plinth from the ceiling surface by a dozen centimeters will allow you to lay in it led strip, providing the ceiling with hidden lighting.

How to cut the corners of skirting boards: solutions for different materials

In this article I will talk about how the floor and ceiling plinth is adjusted in the corners. As you know, it is made from different materials, and the reader and I will have to analyze the features of each of them.

Plastic

Floor

Here, cutting as such is not required: in the outer and inner corners, the planks are joined by corners; connectors are used for longitudinal docking.

From this, there are two obvious conclusions:

• The plinth is cut at right angles to the longitudinal axis;
• Trimming accuracy may not be perfect. Please allow 1-2mm error.

The strap may be slightly shorter than the required size.
If you cut it off with a margin, one of the planks that join at the corner simply will not adhere to the wall.

I cut the bars like this:

1. I set the corner to the nearest corner and insert the bar into it until it stops;
2. I mark the position of the next corner or connector;
3. I deviate from the 3 mm mark, on which the plinth will enter the connector or corner;
4. Having laid the plinth on a flat surface and applying a building square to it, I draw a line perpendicular to its longitudinal axis. Small deviations, inevitable due to the complex shape of the section, will not make the weather: as we remember, they are permissible;
5. I cut off the bar with a grinder with a cutting wheel for stone or steel. The cut is very accurate and without burrs, unlike any saw; a knife (even the sharpest one) often breaks fragile plastic due to strong pressure.

If truncated, I do it in this order:

Why is the lid cut separately? Because its displacement during cutting often leads to the fact that the length of the cover is 1 - 2 mm less than the length of the plinth. The untidy gap between the cover and the connector, you know, is useless to us.

Ceiling

Ceiling plastic skirting boards and starter profiles are primarily used in assembly false ceiling from plastic wall panels. Such a ceiling is very practical in the bathroom or in the kitchen: it collects a minimum of pollution, is easy to clean and absolutely indifferent to humidity fluctuations.

Corner and connecting fittings, however, are not provided for skirting boards and edging profiles. How to cut the corners of the ceiling plinth in this case?

Cutting in the chair

A miter box is a simple carpentry tool, which is a tray made of plastic or plywood with slots at angles of 90 and 45 (less often - 30 and 60) degrees to the longitudinal axis. The retail price of a plywood miter box is no more than 200 rubles.

How to cut corners on skirting boards with this tool?

1. We lay the plinth or profile in the miter box tray, pressing it tightly against one of the side walls;
2. We take a hacksaw for metal and cut off the plastic along the slot at an angle of 45 degrees, pressing the canvas to one side of the slot. It is a hacksaw for metal that is needed here because its small teeth do not break plastic (unlike a hacksaw for wood) and leave minimal burrs that are easy to clean with a sharp knife.

Do not forget that at the outer corners, the edge of the plank does not fall on the corner, but protrudes beyond it by the width of the adjacent plank.

The instruction is extremely simple and ... often gives a disgusting result. The fact is that the slots in the miter box have a width just under the carpenter's hacksaw for wood; a thin sheet of metal dangles in it, as ... I think the dear reader will choose the appropriate association for himself.

As a result, no matter how hard you try to cut exactly at an angle of 45 degrees, the canvas will lead at least a little bit to the side.

Cutting with marking in place

How to cut corners on a ceiling plinth with more precision and/or without a miter box?

Spatial imagination will help us. If we mentally combine both plinths in the corner, then it turns out that the lines of the proposed cuts must pass through the points of intersection of their edges.

1. We apply a plinth or profile to the place of permanent deployment and draw lines with a pencil along its edges on the wall and ceiling;
2. We repeat the operation with the second plinth;
3. We apply both planks alternately again and mark on them the points of intersection of the edges with the lines marked along the edges of the adjacent plank;

1. Using a ruler, we connect the dots on each plinth;
2. Laying each plank on level ground, cut it off with a grinder with an abrasive wheel, keeping the plane of rotation of the disk strictly vertical.

Using this method, even cutting the corners of the ceiling plinth at angles other than 90 degrees will be accurate.

Foam, polystyrene, polyurethane

How to cut corners on ceiling moldings made of foam and other foamed polymers?

Both of the above methods of bevel cutting in corners are also suitable for this material.

There are, however, a number of subtleties.

• Polystyrene and materials based on it should never be cut with a hacksaw, abrasive disc or other tools that cause intense heating of the cut area. The fusible polymer melts and hangs in untidy burrs or drops. For cutting, only and exclusively sharpened knife with the thinnest blade is used;

The tool is a thin and sharp knife.

During the cutting of the plinth in the last room I finished with an area of ​​​​about 19 m2, I sharpened the knife three times.
The first sign that your tool is too blunt is that when cut, the foam begins to crumble, and part of the cut exposes its granular structure.

• When using a sufficiently long knife, cutting in a miter box gives a very decent result. The secret is simple: it is much easier to press the knife tightly against one of the sides of the slit of the miter box.

Wooden

Cutting a wooden ceiling fillet or floor plinth is performed:

1. In a miter box with a regular garden hacksaw. The width of its teeth at correct wiring matches the slots in the miter box quite accurately, and possible deviations of the cut line are minimized. To avoid chipped edges, avoid strong pressure;

1. A very accurate cut is obtained if it is marked in place when using a grinder with a diamond wheel. Unlike abrasive discs, diamond discs do not char the edges. The main thing is not to rush, to drive the disc along the marked line with minimal speed, pressure and in a strictly vertical position.

Useful little things

• It is easy to seal the seams between polystyrene foam or polyurethane ceiling plinths with acrylic putty on concrete. I have been using it lately for sticking skirting boards and filling cavities between the irregularities of the latter. For stickers, putty is applied to both planes of the plank, which are pressed against the ceiling and wall. Tool - spatula;

• In the corners of wooden baseboards, the cracks are sealed with acrylic putty on wood, matched to the tone. You can also prepare putty with your own hands: just mix PVA glue with sawdust left over from cutting;

Sawdust for putty is collected in separate container when sawing wood and in no case are swept off the floor.
The estimate will inevitably contain dust, which will affect the color of the impromptu putty.

• Floor skirting boards with cable channels are convenient even if you do not plan to hide wiring in them or twisted pair local network. They allow you to securely fasten the bar with ordinary dowel screws and hide the fasteners.

Conclusion

I hope that my experience will be useful to the reader. See more clearly how skirting boards are cut in different occasions, the video in this article will help. Please feel free to leave your additions and tips in the comments. Good luck, comrades!

Correctly forming the corners of the ceiling plinth is very important: this element of decoration is always in sight. Bad docking can spoil the impression of the repair. But this is not an easy task: by cutting the plinth at 45 degrees, you will not get the desired result (gaps will remain). Your attention to expert advice on how to cut down the corner of the ceiling plinth.

Trimming should be carried out along the outer edge of the plinth, as well as from the inside (when forming the outer corner) or front side(for internal docking). If everything is done correctly, the texture of the cornice will not be violated. Most commonly used at home Decoration Materials from foam. The technology of joining elements is as follows.

1. Using a protractor, the angle between the walls is measured. In the event that it is strictly equal to 90 °, you need to cut the edges at 45 °. The action is performed on both elements.
2. If the joints between the ceiling and walls are not even, the corner radius should be halved. In this case, the baguette, which will be attached on the left side, is cut off on the right, and the right element, respectively, on the left.
3. The edges of the details of the inner corner are cut so that top part was shorter than the bottom. The edges of the outer corner are formed differently: the lower part is shorter than the upper one.
4. Unlike foam skirting boards, wooden details it is required to precisely adjust to each other and to adjacent surfaces, applying and cutting along the junction line.

Ceiling plinth (corners): the photo demonstrates the techniques for trimming and joining elements:

What tools can be used to cut corners

1. It is convenient to cut corners with a miter box and a miter saw. Smaller jobs can be done with a hand saw with fine teeth.
2. If it is necessary to change the cutting direction, a jigsaw is used.
3. You can cut a narrow foam baseboard with a construction knife or a hacksaw.
4. The markings on the plinth are applied with a simple pencil, the traces of which are erased after installation.

We cut the ceiling plinth (outer corner): a video with explanations will be a good help to a novice master.

How to cut a skirting board without a miter box

Let's say you urgently need to stick a ceiling plinth. How to make a corner without a miter box? It is possible, although it will take more time. You should act in this order.

How to cut a corner of a ceiling plinth: a video with expert comments will help you deal with this problem.

Advice! Since it does not always have perfect shape internal or outer corner, the ceiling plinth will have noticeable gaps at the joints. To make them less noticeable, gypsum putty should be applied to its ends before gluing the plinth. After joining the elements, the excess putty is removed with a rubber spatula. All gaps will be filled and the junction will be less noticeable.

It is not easy to glue and correctly join fillets with a pattern. How to proceed in such a case? The video will tell you the answer.

Docking skirting boards with decorative corners

In the event that the walls are perfectly prepared, and the external and internal angles are 90 °, it is possible to use special decorative elements for joining plinth fillets. The advantages of this method:

• ease of installation: there is no need to “fill your hand”, improving the technique of trimming the details of the plinth;
• saving time: to join the elements, you just need to cut them at a right angle and attach the decorative part.

The decorative parts themselves for joining fillets are intended:

• for internal corner joints;
• for external (external) corner joints;
• for joining straight parts.

This connection method is the only option in the case of installing a plastic plinth, which cannot be trimmed without gaps.

Sealing the joints of ceiling plinths

No matter how carefully the work is done, the joints between the plinth fillets will be noticeable. This defect can be eliminated as follows.

1. Glue is applied to the joints of the plinth.
2. After connecting the elements, excess glue is removed with a clean cloth. Do this after the glue has completely dried.
3. The gaps between the plinth, ceiling and wall are rubbed with a mixture of gypsum putty and water-based paint with a rubber spatula.

This method is suitable for masking defects when connecting wooden skirting boards, as well as fillets made of polyurethane foam, polystyrene foam, polystyrene foam. In some cases, white sealant can be used.

Using the tips in this article and necessary tools, you can independently cut and join the fillets of the ceiling plinth.
