The device of monolithic coatings
4.25. Monolithic mosaic coatings and coatings with a hardened surface layer, arranged on concrete underlying layers, should be performed simultaneously with the latter by embedding decorative, reinforcing and other bulk materials into a freshly laid evacuated concrete mixture.

The device of coatings from slabs (tiles) and unified blocks
4.27. Slabs (tiles) of cement-concrete, cement-sand, mosaic-concrete, asphalt-concrete, ceramic, stone-cast, cast-iron, steel, natural stone and unified blocks should be laid immediately after the installation of a connecting layer of mortar, concrete and hot mastics. Embedding plates and blocks into the layer should be carried out using vibration; in places inaccessible for vibroheating - manually. The laying and embedding of slabs and blocks should be completed before the mortar begins to set or the mastic hardens.
4.28. The main requirements that must be met when installing coatings from slabs and blocks are given in Table. 22.

The device of coatings from wood and products based on it
4.29. Logs under the coverings should be laid across the direction of light from the windows, and in rooms with a certain direction of movement of people (for example, in corridors) - perpendicular to the movement. Logs should be butted together end-to-end anywhere in the room with a displacement of joints in adjacent logs by at least 0.5 m. Between the logs and walls (partitions) it is necessary to leave a gap of 20-30 mm wide.
4.30. In floors on ceilings, the surface of the log should be leveled with a layer of sand, padding it under soundproof pads or logs along their entire width or length. The joists must touch the soundproofing layer, floor slabs or sandy leveling layer with the entire lower surface, without gaps. Knocking wooden wedges or linings under the logs to level them or resting the log on wooden linings is prohibited.
4.31. Under the logs, located on the posts in the floors on the ground, wooden spacers should be laid on two layers of roofing, the edges of which should be released from under the spacers by 30-40 mm and fastened to them with nails. The joints of the lag should be located on the posts.
4.32. In the doorways of adjacent rooms, a widened log should be installed that protrudes beyond the partition by at least 50 mm on each side.
4.33. Plank flooring boards, parquet boards, connected to each other by side edges into a tongue, and parquet boards - with dowels, must be tightly rallied. The reduction in the width of the coating products during rallying should be at least 0.5%.
4.34. All plank floor boards must be fastened to each joist with nails 2-2.5 times longer than the thickness of the floor, and parquet boards - with nails 50-60 mm long. Nails should be hammered obliquely into the surface of plank flooring boards and into the base of the lower cheek of the groove on the edges of parquet boards and parquet boards with sunken caps. Driving nails into the front surface of parquet boards and parquet boards is prohibited.
4.35. The joints of the ends of boards of plank coverings, the joints of the ends and side edges with the ends of adjacent parquet boards, as well as the joints of the edges parallel to the logs of adjacent parquet boards should be located on the logs.
4.36. The joints of the ends of the boards of the coating should be covered with a board (frieze) 50-60 mm wide, 15 mm thick, cut flush with the coating surface. The frieze is nailed to the log with nails in two rows with a step (along the log) of 200-250 mm. Docking of the ends without overlapping with a frieze is allowed only in two or three wall boards of the covering; joints should not be opposite doorways and should be located on the same log. When pairing parquet boards, as well as parquet boards with sawn edges, a groove must be made on some of them, on others - a comb corresponding to those on the other edges.
4.37. Superhard fibreboards, type-setting and block parquet should be glued to the base with quick-hardening mastics on waterproof binders, applied in a cold or heated state. Adhesive mastic on the base for superhard fiberboards should be applied in strips 100-200 mm wide along the perimeter of the boards and in the middle zone with an interval of 300-400 mm. When laying out and cutting fiberboards, joining the four corners of the boards at one point is not allowed.
4.38. When installing coatings made of wood and products based on them, it is necessary to comply with the requirements of Table. 23.

The device of coatings from polymeric materials
4.39. Linoleum, carpets, rolled materials made of synthetic fibers and PVC tiles before gluing must be aged until the waves disappear and completely adhere to the base, they must be glued to the underlying layer over the entire area, except as specified in the project.
4.40. Cutting of joined panels of rolled materials must be done no earlier than 3 days after the main gluing of the panels. The edges of the joined linoleum panels must be welded or glued after cutting.
4.41. In areas of heavy pedestrian traffic, the device of transverse (perpendicular to the direction of movement) seams in coatings made of linoleum, carpets and rolled materials made of synthetic fibers is not allowed.
