Surface preparation
The surface must be dimensionally stable and free from dust, grease and laitance as well as blooms and form oil residues. Remove grease and soap residues with Alfix Deep Cleaner.
Prime extremely absorbent substrates with Alfix Primer diluted 1:3 with water. Room temperature should not be below +10ºC. The primer must be dry before further application. 
Application
Apply Alfix 1K Sealing membrane to the substrate in a layer of approx. 0.5 kg/m² ensuring full coverage. Use a roller, brush or a trowel for the work.
Immediately after, press the Alfix Waterproofing membrane onto the moist sealing membrane, ensuring full contact with the substrate without air pockets. When joining more membranes, it is important that they do not overlap. Cut any overlaps to ensure that there is only a single waterproofing membrane layer.
