Facing by plastic and wood-fiber plates

Bumazhno-layered plastic to vertical surfaces of the plastered, plaster and concrete walls can be glued kumarono-nejritovoj mastic КН-3. Plastic sheets raskraivajut on the sizes defined as a result of a marking of walls. Thus sheet stack all plane on a table a face sheet upwards. Plastic can be cut a saw with small and frequent teeths or nozhovkoj on metal. A saw hold at an angle 30°. It is not necessary to press a cloth strongly, especially at return movement as it is possible to break out and jag sheet edges. Bumazhno-layered plastic and disk saws with small nerazve-dennymi teeths is well cut. Edges process a plane.

One days prior to gluing gear shpatelem with height of teeths 1 mm put mastic on a sheet underside. For 20-30 mines to a label a sheet surface again coat with a thin layer of mastic and maintain to a condition when mastic poorly sticks to a finger.

To Paste sheets it is necessary on carefully marked surface. The first sheet glue from a premise corner according to the vertical line put by means of a plumb. Sheet bring to a wall, put to it and grind in from the middle to edges rags. In the same order krepjat other sheets between which it is necessary to leave a backlash in width of 10-20 mm taking into account possible expansion of sheets at temperature fluctuation. Seams cover with wooden apportions.

To wood bumazhno-layered plastics can be pasted karbamidnymi glues К-17, М-70, КВ-3, НА-1. Glues quickly harden - during 3-5 ch, therefore them prepare directly ahead of use. The glue structure includes mochevino-formaldegidnaja pitch (100 parts on weight), 10%-s' solution shchavelevoj acids (28 parts) and a wood flour (3 parts).

For gluing of thick bumazhno-layered plastics, firm wood-fiber plates, decorative and bakelizirovannoj plywood to the plastered and concrete surfaces it is possible to use polivinilatsetat-cement mastic which prepare on a basis polivinilatsetatnoj emulsii (1 part), portlandtsementa (1,5-2 parts) with addition of a small amount of water (0,2-0,3 parts). To put on a surface of plates such mastic follows not a thin layer as it do at use of glues, and gear shpatelem with teeths of 1,5-2 mm. The finished surface (ferro-concrete or plastered) should be equal, without flows and acting grains napolnitelja that will provide good prileganie a facing plate. For the best coupling of facing sheet it is possible to put a layer of coarse-grained sand or other any Droblenogo of a material on its back party from a natural stone with the size of grains to 2-3 mm in diameter.

At pasting by plastic of the small area it is possible to use epoksidnyj glue.

Wood-fiber plates with a decorative obverse surface paste the same as also bumazhno-layered plastic. However the choice of gluing mastics in this case is slightly wider: it polivinilatsetatnaja emulsija, mastics "…ѕё=шыр=" kanifolnaja, kumaronovaja and difenolnaja. Too it is necessary to cover joints with apportions.

Bumazhno-layered plastic, wood-fiber plates and sheets decorative and bakelizirovannoj plywood it is possible krepit to a wooden skeleton. Unlike a skeleton arranged for fastening drevesnostruzhechnyh of plates, bruski a skeleton for the specified materials it is necessary to have vertically so that sheets were joined on bruskah. If sheets short, in joining places establish also horizontal bars of a skeleton.

That sheets did not cave in at opiranii on a wall, between skeleton bars do a lattice from reek with cells 30X30 see

Sheets krepjat to a skeleton nails or screws. At facing by plastic it is necessary to consider its considerable temperaturno-vlazhnostnye deformations and to leave a necessary backlash between sheets, and fixing apertures in sheets it is necessary to do on 0,5-1 mm more than diameter of screws or nails. To avoid formation on a surface of sheets of cracks, it is recommended to apply screws and nails with lining washers.
