ISOMAT AK-BLOCK is used for fixing aerated concrete elements.
The aerated concrete elements must be free of dust. ISOMAT AK-BLOCK is gradually added into water under continuous stirring, until a uniform paste is formed. A low revolution mixer is recommended for mixing. The mixture should be left about 10 minutes to rest and should be stirred slightly again. The mortar is spread on the substrate using a notched trowel, in order to be applied uniformly on the whole surface. The aerated concrete elements are fixed by pressing them in the desired position.
