The Durability and quality of furnish by film and rolled materials substantially depends on carefulness of preparation of the basis. The pasted over surface should be equal, smooth and dry, especially at gluing of thin wall-paper or bezosnovnyh and self-glued films as the slightest bowl and even grains of sand will be shown in the form of a dent or bugorka. It is not recommended to paste over with wall-paper and films constantly damp surface of a wall as it will lead otslaivaniju and damage of a finishing material.
Preparation of any surface intended under pasting by film and rolled materials, consists usually of several basic operations.
Repair and surface clearing from pollution include the same operations, as well as for painting works. Visible cracks on a surface, and other defects cut hollows, clear away steel shpatelem to places with strong plaster and close up a corresponding plaster solution. Insignificant cracks, cracks, apertures from nails only cut steel shpatelem and strongly close up shpaklevkoj. All repaired places before pasting by wall-paper should be dried. After repair the surface follows well proshlifovat an emery paper, deleting roughnesses and separate grains of sand.
The Walls earlier painted by glutinous or limy paints, completely clear from nabela water and shpatelem. In more details this operation is described earlier.
Stains on a surface of walls if they can appear through wall-paper, it is necessary to paint over a nitrovarnish, nitroenamel or to stick with a thin aluminium foil.
If walls are pasted over by simple wall-paper, it is necessary to check up, how much strongly they keep. For this purpose it is enough to moisten a surface with water. Places where there will be swellings, it is necessary to clear of wall-paper. If old wall-paper keeps strongly on them it is possible to glue new, preliminary having smoothed out an emery paper separate roughnesses and places of breakage of old wall-paper, and also well having glued their hot paste.
All other kinds of the film and rolled materials pasted earlier, are subject to removal.
It is not necessary to delete Oil colouring. It is necessary for washing out water with soda or soap and it is good to dry. A surface painted by enamels, also wash out and clear an emery paper.
If the surface is upholstered by dry plaster plaster or gipsokartonnymi sheets, at first a plaster solution shpatljujut joints, then paste over with their gauze, again shpatljujut and smooth out an emery paper. Nails utaplivajut on depth of 1 mm, paint over hats an oil paint, deepenings shpatljujut and after drying grind.
Surfaces from drevesnostruzhechnyh, wood-fiber plates and plywood are prepared similarly. Seams in joints of sheets and places of the hats of nails drowned in sheets close up shpatlevkami for wooden products. The dried surfaces grind and clear of a dust.
The Board surfaces intended under pasting by film and rolled materials, are preliminary upholstered DVP or a cardboard with the subsequent performance of the operations described above.
At furnish by synthetic film materials, after procleaning, repair and a first coat of walls mylovarom rough places or all surface repeatedly shpatljujut also grind pumice and an emery paper. The surface prepared thus glue (ground) the dissolved glue accepted for a label of the given material.
The Exception is made by the surfaces intended for pasting by an isocaptivity of marks AV and BV. In this case it is possible to be limited only to repair and procleaning of walls with their subsequent first coat. The considerable thickness of a material allows to exclude such operations, as continuous shpatlevka and polishing.
Otbivku of the top line provide in all cases, besides, when furnish is carried out to a ceiling. The necessary distance from a ceiling to furnish top is marked by a pencil or a chalk in premise corners on each wall. Then by means of a cord rubbed with a pigment or coal, the line beats off.
In connection with that that in some premises the ceiling line is not always horizontal to a mark of the top line of furnish, it is expedient for checking up by means of water level.
Proklejku or a first coat of surfaces carry out the dissolved glutinous structures or the mastics intended for a label of film and rolled materials. This operation is necessary for fastening of the smallest grains of sand and others pylevidnyh particles which can affect quality of glutinous connection.
Before gluing of simple paper wall-paper the surface is coated with paste. At first do otvodku - coat below a line top otbivki a strip of 4-6 sm, and also At apertures, in corners, at plinths, then all surface glue with the help mahovoj brushes.
Paper for recycling use at primary pasting of walls by wall-paper for the purpose of surface alignment. For this purpose apply, as a rule, newspapers which are better pasted to svezheoshtukaturennoj surfaces. It is the most convenient to do this operation so: the prepared paper pile, mahovoj a brush put glue on the top sheet, paste it on a wall and smooth with rags before disappearance of wrinkles and bubbles. The thin paper is pasted vnahlestku, more dense - end-to-end. After prosyhanija sheets all remained wrinkles and roughnesses smooth out an emery paper.
The Surfaces intended under pasting by films on a paper or fabric basis, follows proolifit and proshpaklevat. If with wall-paper paste over smooth equal surfaces (plaster, concrete), them ground a solution of glue KMTS, mastics "…ѕё=шыр=" or "+ѕьшыръё" (depending on what glue will be used for gluing of wall-paper). In the same way prepare a surface for isocaptivity gluing.
Surfaces under pasting bezosnovnymi and self-glued films, and also vinistenom should prepare the same as under high-quality oil colouring.
