Note: wall of foam is important to keep the right balance was the inner and outer layers of plaster.Furthermore, under the outer layer of plaster on the wall and should not accumulate moisture, in other words, the wall must "breathe."If not provide all of these conditions, the constant water freezing and thawing in the outer layer will crack and the inner - mold.
plaster must not be too thick, the optimum thickness of the outer layer is from 5 to 10 mm, and the inner layer - 10-20 mm.The plaster dries by itself for a long time, so to speed up this p
rocess, make sure that the temperature in the room where the finishing work performed, ranged from 5 to 30 degrees (not below this level).
Before applying the plaster is required to treat the walls: for this prime with the surface.Following this, prepare a solution: Mix one part cement with sand and three parts water, and after all these components mix well with a mixer.
Using a spatula, apply the solution on the wall, although it is easier to apply the method of slap: to do this, take the left hand grater, which put the prepared mixture, and biting the wrist nabroste solution on the pre-moistened with water walls.After fill the entire surface of cement mortar, smooth circular motion float smooth the deposited layer, adding a spatula into the empty place cement.
To make a smooth corner, attach using screws or other fasteners board (the board will expose on the level).Oshtukaturte wall along the board, and after the applied layer dries, remove the board.
Tip 2: How to plaster foam
Foam must be protected against humid and carbonization shrinkage.For this it is necessary to restrict access thereto of atmospheric air.The most reasonable measure of foam blocks - plaster.You can use it to improve the overall characteristics of the walls.
to start correctly pick up the plaster.It must be vapor permeability.Also pay attention to the thickness of the inner layer.For aerated concrete wall she should become a barrier penetration of steam and air.Note the amount of steam that comes in through the interior wall plaster, in full should come out through the outer layer.Steam should not be left inside the wall.Otherwise cracks will appear.The outer layer will begin to fall away, and the inner will always be wet.
to facade walls could breathe, it is recommended to make the outer layer thickness is twice smaller than the inside.For example, if the outer layer has a thickness of 20 mm, the extension should be 40 mm.Do not put on the wall of the foam thick layer of plaster.Take the outer layer of 5 mm, and the internal - 10 mm.
Note wall of foam does not absorb moisture.The plaster dries out.That is why you can accurately align the layer.Note surface blocks.If foam concrete blocks produced by the cutting technology, the plaster on them will keep a lot worse, since they have a rough surface.Blocks, produced by casting into molds, it is necessary to work well cleaned and sanded.By doing so you remove the top layer is hydrophobized.
If you are going to plaster molding foam, use plasters with higher adhesion.The fact that ordinary plaster will adhere poorly to such concrete blocks because of the large hydrophobic foam.If you are going to plaster walls are built of poor materials absorb moisture, then the first phase of the spray layer of the solution on them, and then apply the basic plaster layer.
- plaster foam
plaster can not be processed, so the excess solution should be immediately removed.
Note: if you need to plaster ceiling and a layer applied in this case is two centimeters thicker, must be installed to use the flashing profiles and reinforcing mesh.Ceiling plaster desirable solution having high adhesion properties.
