So that long -awaited moment came when the construction of a house using aerated concrete blocks is completed. The question arises of how best to finish the facade? And the correct requirements for this are very necessary. After all, the facade should be not only in a beautiful performance, but also perform the protective functions of the blocks themselves, protect the house from the cold and excessive moisture.
Aerated concrete blocks in their structure have open pores with a developed system of moves, and therefore any decoration will not suit them. For example, they cannot be plastered with ordinary cement mortar and painted with paints that create a film, as this prevents the withdrawal of air vapors out of the internal premises of the house. But you can’t leave blocks without finishing – the pores of blocks absorb dust and rain water over time, which leads to surface pollution and moisturizing the walls, and this significantly reduces the thermal insulation qualities of the walls themselves. Of course, it is possible to clean the polluted walls, how to do it here, but it is better to immediately finish.
In what ways can external blocks of blocks be done?
For cladding, decorative panels, a finishing board and other hinged materials with good ventilation are suitable, this will allow you to apply additional insulation materials.
You can cover the blocks with facial bricks, necessarily leaving a small gap between it and the wall from 30 to 50 mm, are produced for plastering and special mixtures that create a thin layer and contribute to the necessary ventilation. And the seams between the blocks can be wiped and subsequently painted with textured paints that have the ability to pass steam.
Is the front brick suitable for decoration?
If it is decided to finish the facade with facing bricks, it is advisable to take this into account even when pouring the foundation of the house on which aerated concrete blocks will be located and the front brick will be located. Masonry is carried out in half a brick and the allowable overhang from the foundation should be no more than 30 mm. It is necessary to make a ligament between the cladding and the main wall (allowed for 1 sq. meter 4 links for connecting a stainless bandage or galvanized tape). So that there is ventilation in the gap, you need to leave small holes near the cornation and leave in the masonry. Such a facade will simultaneously look beautiful and protect the blocks from the adverse effects of moisture and sunlight, preventing rapid wear, increasing the service life of aerated concrete block. After the facade decoration, you should call on the facade materials care products.
