Surface preparation plaster - pedantry welcome

it good to be meticulous?In relations with people - it is doubtful, but in the work, especially when you need to the sea of ​​patience, even prudery welcome.In particular, it is important to be scrupulous, meticulous (but call it what you will) in the preparation of walls under plaster, when the slightest defect can result in catastrophic consequences after finishing.The surface of the wall on which you plan to apply the plaster should be perfectly clean.But to overdo undesirable - with soap and water is best not to wash the wall, adhesion (adhesion) will not.

The first step is to carefully examine the entire surface of the wall and to identify areas that can be showered afterwards.They must be removed at once, because even if they are removed in the process of removal of dust, just dust obvalivanie such sites and will add.When all the seats will be unreliable completely eliminated, it is time to proceed to the second stage of surface preparation plaster - scrubbing dirt and dust.Scrape every centimeter toothbrush does not make sense, because the uneven wall dust can be quite matted and cleaning one square meter will take more than one day.So just take a damp cloth and thoroughly laundered wall (and just should not miss a single centimeter).

Preparation of walls under plaster - deepening irregularities

thereby forming a coupling of a plaster layer and the surface of the wall?Only due to the irregularities of the latter, and if the wall is relatively smooth, the surface should be deliberately distort.Of course, with the hammer and hammer in such cases does not necessarily grab enough hammer and chisel to break through the small slots and grooves over the entire surface of the wall.When irregularities will, in your opinion, enough, you can stop their destructive activities, and developing creative, pre-again having washed walls.

In some cases, when there is no possibility furrow wall artificial ruts, it is secured grid, while plastering the tree - a specially prepared wooden lath (torch up to two meters and a width of 15 to 30 millimeters).Grid with cells 30x30 millimeters (less can be more - it is not necessary) is stretched very tight to never sag and Bouguereau, lath is nailed to the floor diagonally, at an angle of 45 degrees, in two layers crosswise.Dimensions drani cells should not exceed 40 millimeters.If the wood surface somewhere fit in with brick or concrete, at the crossing also stretched mesh.When this phase of work is completed, we continue to prepare the walls under plaster.

With the help of a plumb and level (preferably a laser) reveal all the irregularities of the wall.The main task of plaster - to make the wall as straight as possible, so you need to take into account the curvature of each of its surface.When using a marker or otherwise marked all the bumps and hollows in the plane of the walls in the room begin to place beacons.This kind of levels, the only constant, they are hidden under the plaster.A lighthouse on the ledge, is shorter than the other, in a hollow - longer.In general, all the tips of the columns beacons (which may represent nails or screws) should be on the same plane.When everything is ready, we obtain a primer.

Preparation of walls under the decorative plaster a few strokes

So what we have.Depending on the material from which is made our house walls or warped using a chisel, or covered with a grid, covered with shingles or (as an option - all together or in combination).Therefore, we can only properly primed wall.Take a soft brush, pull out beforehand acquired a special primer or, at worst, varnish, and start each promazyvat uchastochek.If the grid is stretched, then tried to cover the primer each wire - it will prevent the grid from rust, unless you use chain-link fencing with a polymer coating.It is also coated with a primer beacons slots punched in the concrete, in general - everything.

When the last touch will be made, waits a couple of hours and passes through the wall a second layer.Still 5:00 result of our work will be dry, and then ... Then you can proceed directly to the plastering of the walls, and then to other stages of the finishing works in the apartment.The main thing do not forget that the tips of the lighthouse, you stuffed before, must hide in the thick plaster to a depth of not less than a centimeter.Well, stack or lath should be hidden even the first rough layer of plaster.

But then you will be able to live for decades in high quality stucco house without worrying for the integrity of the walls, and from time to time oglazhivaet hand flat surface that hides in itself so to help you out beacons.
