As the Basis under a covering so-called subfloors from various materials can serve. They should be equal, without hillocks and dredging. After all even the mote imperceptible approximately which has appeared under linoleum, owing to its elasticity will look bugorkom. Besides, dust presence on the basis reduces durability of gluing of linoleum and tiles.
Therefore after preparation of its basis it is necessary to sweep well at first with a usual broom, then a brush, it is possible to use and a vacuum cleaner.
If floor boards cave in at walking such floor is not suitable for nastilki linoleum or tiles as in places of a deflection it quickly becomes unfit for use.
The Prepared bases check fugovannoj a ruler (rejkoj) in the length 2 m. Separate gleams between it and the basis should not exceed 3 mm.
If the bases cold or very rough, correct them: the wooden close drevesno-fibrous plates (DVP); concrete, brick and others level a cement-sandy solution, or as speak, a coupler, or also plates DVP. Before nastilkoj linoleum, tiles or synthetic carpet materials the basis from what it would not be executed materials, should be dry. To the dry basis mastic is better pasted, strongly keeping the pasted material.
the Wooden bases carry out from dry boards in width no more than 100 mm. Boards should be stacked year layers every which way. At such packing more equal basis almost subject korobleniju turns out. After nastilki boards of a hat of nails should be drowned in thickness of wood that they did not spoil the tool during time strozhki.
Planing is good for carrying out by car, but it is possible and manually - at first across, then along fibres. After that surfaces are recommended to be ground a skin, having wrapped up it wooden brusok: so it is more convenient to hold a skin, and work moves faster.
All places with defects of wood correct by shpatlevanija. In general, if the surface not so pure, is better than it at first proolifit, and then proshpatlevat for one-two time semioil shpatlevkoj. Over hats of nails it is necessary to cover places zapodlitso with the basis. This puttying, probably, it is necessary to execute for two-three times so that after zachistki shpatlevka was strictly on one, level with a wooden flooring. If it is below the basis over this place linoleum will give. If shpatlevka will be above the basis on a surface of linoleum or tiles there will be a height - bugorok. In any case it conducts to fast deterioration of a covering.
To Lay linoleum or tiles on old wooden or parquet floors it is possible only in the event that they strong and boards at circulation do not fluctuate. Caving in boards of a floor re-make, necessarily stacking under them additional logs which have so often that boards did not cave in. Boards at nastilke (or perestilke) rally - compress as it is possible more densely. A floor plane. If between boards there are cracks, they are closed up wooden rejkami with the subsequent pristrozhkoj. Narrow cracks between boards preliminary clear away from a dust and a dirt, olifjat, dry and only then cover semioil or oil shpatlevkoj. SHpatlevku well smooth out.
Not always it is possible shpatlevkoj to correct rough defects. Then it is necessary to close a floor semifirm drevesno-fibrous plates.
The Concrete bases necessarily level, if they do not meet necessary requirements. If the concrete bases basically equal, but places have defects they should be eliminated: hillocks cut down, and hollows fill with a cement-sandy solution with the help shpatelja, well level and rub clean. Sometimes it is necessary to grind in addition pumice or a skin.
If concrete, stone or brick surfaces rough, it is necessary to do a cement-sandy coupler, i.e. To put a cement mortal. The put solution well level and rub clean or smooth down poluterkom with the beaten strip of rubber. (Rubber is necessary that the coupler was slightly rough for improvement of coupling with it of glue or mastic.)
The Coupler carry out from a cement-sandy solution of structure from 1:3 to 1:5 (in parts on volume): 1 ch. Cement of mark 300-400 and 3-5 ch. Sand. Sand is necessary for sifting through a fine sieve with apertures not more largely 3x3 mm.
The Prepared solution should have a consistence of the dense test and durability after tverdenija within 5-10 MPa (50-100 kg/sm2). Sand should be very well mixed with cement. At zatvorenii water this operation repeats. The solution should be absolutely homogeneous.
The structure Solution 1:3 is more convenient for packing, than a solution 1:5, but in the first case the cement expense increases.
The Concrete, stone or brick basis clear of a dust and a dirt, well sweep, moisten with water, and as soon as it will be absorbed in the basis, start solution packing. A solution on the basis put separate hills which level poluterkom, rubbing clean then a grater. A thickness of a layer of a coupler of 20 mm. More thin coupler can quickly collapse.
Leveling poluterkom to well qualified experts or those who has well mastered technics of levelling of a solution. That who never was engaged in it, it is better to arrive so: to plane wooden rejki on a thickness of a coupler, to lay them on the basis on distance of 1,5-2 m one from another strictly at one level and to fix. (If in places rejki cave in - to enclose wedges.) thus establish so-called wooden beacons on which a solution level rejkoj or a board.
is final, beacons can be and thicker, but a solution then it is necessary to level malkoj (rejka with cuts). Thus beacons should be put strictly on certain distance from each other that between them could be located malka (fig. 46).
