1. Facing of surfaces is necessary for carrying out according to PMW (the project of manufacture of works) according to the project. Connection of a field of facing with the basis should be carried out:
- At application of facing plates and blocks in the size more than 400 sm 2 and thickness more than 10 mm - fastening to the basis and with filling with a solution of space between facing and a surface of a wall (bosoms) or without priming bosoms a solution at pertinence facings from a wall;
- At application of plates and blocks in the size of 400 sm 2 and less, thickness no more than 10 mm, and also at facing by plates of any sizes horizontal and inclined (no more than 45 %) surfaces - on a solution or mastic (according to the project) without additional fastening to the basis;
- At facing by mortgage plates and a facing brick simultaneously with a laying of walls - on masonry mortar.
2. Facing of walls, columns, pilasters of interiors of premises should be carried out in front of the device of a covering of a floor.
3. Elements of facing on a glued layer from a solution and are necessary for establishing mastics horizontal lines from below upwards from a corner of a field of facing.
4. It is necessary to render mastic and a solution of a glued layer uniform, without runs, a layer prior to the beginning of installation of bars. fine-sized bars on mastics or solutions with decelerator should be established after drawing the last on all reveted area in one plane at thickening mastics and solutions with decelerator.
5. Furnish of a site and all surface of an interior and a facade and the sizes should be made by facing products of different color, the invoice, a structure with selection of all figure of a field of facing according to the project.
6. Elements of facing at application of a natural and artificial stone polished and glossed are necessary for integrating invoices dry, adjusting edges of the adjacent plates picked up on figure to fastening under the project. It is necessary to fill in seams of plates mastic after priming bosoms a solution and it induration.
7. Plates with ground, dot, uneven and furrowed structure, and also with a relief of type " it is necessary to establish on a solution; vertical seams it is necessary to fill a solution on depth 15 - in 20 mm or germetic after hardening a solution of a gluing layer.
8. Seams of facing should be equal, identical width. At facing the walls erected by a method of freezing, filling of seams of facing from mortgage ceramic plates is necessary for carrying out after thawing and hardening masonry a solution at loadings on walls not less than 80 % design.
9. priming bosoms a solution it is necessary to make after installation of constant or time fastening a field of facing. The solution should be filled in horizontal layers, leaving the ambassador priming last layer of a solution space up to top of facing in 5 see. A solution filled in bosoms, at the technological breaks exceeding 18, it is necessary to protect from loss of a moisture. Before continuation of works the blank part of a bosom is necessary for clearing of a dust the compressed air.
10. After facing a surface from plates and products should be cleared of inflows of a solution and mastic immediately, thus: surfaces glazed, polished and plates and products are washed out by hot water, and ground, dot, uneven, furrowed and type "10 %-ным by a solution of a hydrochloric acid and the ferry are processed with the help sand-jet the device.
11. Surfaces from under has drunk plates of soft breeds (limestone, tufa, etc.), and also acting more than on 1,5 mm of an edge of plates with the polished, ground, furrowed and dot surfaces should be accordingly ground, bright or hewn before reception of a precise contour of edges of plates.
12. By manufacture of facing works requirements of tab. 13 should be observed
