How to use
Apply Alfix 2K 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 Pro onto the moist sealing membrane, ensuring full contact with the substrate without air pockets - make 50-100 mm overlap between sheets. 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.
