BUILDING WITH AUTOCLAVED AERATED CONCRETE

ACRYL M.
More Than Just a Paint.

As with all mineral based exterior building components, autoclaved aerated concrete has to be protected from the elements and the aggressive attack of air contaminants.

Since autoclaved aerated concrete panels are smooth and level, the use of thin coatings can provide decoration and long lasting protection. However these coatings must achieve more than just normal coloring using traditional paints:

of ACRYL M to
normal paints.

FILLING CAPACITY

Autoclaved aerated concrete surfaces have a rough porous structure. To offer perfect weather protection these irregularities must be sealed reliably. For that purpose, a coating with a higher filling capacity than usually needed, is required. By precise selection of filling materials and additives, the application quantity of Acryl M at .37 lbs/ sqft is substantially higher than that of paint, and thus achieves the prerequisite for optimum weather protection (see figure 1 ).

Figure 2. Elasticity test.

ELASTICITY
Due to the good heat resistance characteristics of autoclaved aerated concrete and the resulting higher temperature fluctuations and thermal tensions, autoclaved aerated concrete coatings are subjected to particularly high stress. In order to resist these stresses over many years, autoclaved aerated concrete coatings must have a permanently high elasticity even at low temperatures (see figure 2).

Acryl M meets these requirements by careful selection of high quality polymers utilized in its formulation. This insures that the water vapor permeability is particularly high despite the high polymer content.
