§ E19-35. INSTALLATION OF POLYVINYL ACETATE FLOORS

Characteristics of the conditions for the production of work

The norms provide for the installation of self-leveling mastic floor coverings at an air temperature at floor level of at least + 10 ° C. To protect against mastic pollution, the walls are protected with paper to a height of 50-70 cm. Before applying the mastic, the base is dedusted.

The leveling layer of the coating is applied with mastic with a mobility of 120-140 seconds, and the front layer - 100-120 seconds. The mastic is applied with a spray rod (in the absence of the latter, you can use a spray rod from the S-562 putty unit) or with a spray gun, the diameter of the nozzle nozzle is 4 mm with mastic mobility of 120-140 sec and 6 mm - with 100-120 sec.

Mastic is applied in strips 1.5 m wide from the wall opposite the entrance to the room. The next layer of mastic is applied only after the previous one has hardened. The thickness of the applied layer of 1-1.5 mm each is systematically checked with a metal ruler.

During a break in work, the layer of mastic coating (front or leveling) is reduced "to nothing" and then joined "overlap" (15-20 cm) with the applied subsequent layer of the same composition.

After completion of work and during breaks, containers, tools, mechanisms, hoses, fixtures, taps, valves and plugs are washed with water.

Composition of the work

1. Laying paper at the junction of the floor to the walls (with mechanized application of mastic). 2. The device of the leveling layer. 3. Application of the front layer of mastic.

§ E19-44. CEMENT SCREED DEVICE

WITH APPLICATION OF SOLUTION WITH A SOLUTION PUMP

Guidelines for the application of standards

The norms provide for the installation of a cement screed on interfloor ceilings under parquet floors from cement mortar 35-40 mm thick along a slag or sand layer with mechanized supply and application of the mortar with a mortar pump with a capacity of 6 m 3 /h

§ E4-1-49. Laying the concrete mixture in the structure

Application note

The norms provide for the reception and placement of the concrete mixture by buckets supplied by a crane, conveyor, concrete pumps and dump trucks directly into the structure to be concreted or along trays (trunks), with partial transfer of the concrete mixture. The laid concrete mixture is leveled and compacted with vibrators. The exposed concrete surface is smoothed out. In the process, trays or trunks are cleaned and rearranged.

Composition of the work

1. Acceptance of concrete mix.
2. Laying the concrete mixture directly at the place of laying or along the trays (trunks).
3. Leveling of the concrete mix with its partial transfer.
4. Compaction of the concrete mixture with vibrators.
5. Smoothing out the exposed surface of concrete.
6. Rearrangement of vibrators, trays or trunks with their cleaning.

Notes: 1. When laying concrete mix with "raisin" N.v. and Rass. multiply by 1.2 (PR-1), including laying "raisins". The scope of work is taken together with the "raisin".
2. When laying the concrete mixture in densely reinforced foundations, N.v. and Rass. multiply by 1.1 (PR-2), unreinforced - by 0.9 (PR-3).
3. When laying the concrete mixture in arrays as part of the concrete worker's link 4 razr. be replaced by a concrete worker 3 razr., and Rast. recalculate.
