The dampness in the house of aerated concrete: Causes and Solutions

We used to listen to advertising and trusted manufacturers of building materials. In addition to advertising need to listen to other people's experience, so as not to make mistakes. Let's talk about houses made of aerated concrete and the problems that arise after the construction. Advertising insists that aerated concrete is the best material for building.

Build of this material easily and simply. The material possesses high fire resistance, precise in size, available at a price.

There are a few downsides. Aerated well absorbs water and moisture can almost completely fill the blocks. If you do not expose the material under the influence of moisture, with the thermal conductivity is excellent and all the blocks are intact.

Rumor has it that the house of aerated concrete is difficult to heat the first 2 years after construction. Excess moisture leaves the heating time and aerated concrete homes will be without excessive fuel consumption. To avoid the appearance of mold and dampness in the house want to use plaster with good water vapor.

Many are faced with the question of whether or not to glue the vertical seam. At low temperatures there is condensate and humidity increases aerated vertically without glue seam and ultimately freeze the walls.

How to avoid moisture in the house of aerated concrete?

Masonry blocks should start from ground level up to 50 cm. The porous material is afraid of water. Moisture - is a consequence of insufficient insulation of the foundation, walls, blind area or the ground under the floor. Solution: warm, as the bottom of the house.

We have aerocrete "handle":

They must be zapenivat. If you use a thermal imager, these places are empty and then will collect moisture and freeze wall. If the blocks are already stacked, it is possible to punch a hole in the wall and just zapenit. Then the foam is cut and shpaklyuyut wall.

Use a vapor-permeable materials for external insulation. This may be mineral wool, but not penoplex and polystyrene. Insulation on top of protecting moisture barrier material. After the house is facing.

Blind area must be the same with waterproofing on the perimeter.

It is important to make the ventilation to the house of aerated concrete to breathe. You can use the ventilation with heat recovery. This ventilation with heated air. If you do not make the ventilation, the moisture will accumulate in the coldest places in the house (floor, walls).

Before plastering the wall must be primed in 2 times. First primer diluted with water and carefully go through all the walls. If you do not want to avoid cracks in the plaster walls, it is best to do so. Plastered walls with a thin layer of gypsum plaster, and then paste steloholst fiberglass putty finishing putty.
