Recommended Systems
Mix Keraflex Maxi S1 with clean water until a smooth, lump-free paste is obtained. Leave to rest approximately 5 minutes and re-stir. Use approximately 5.5 litres of water for every 20 kg of powder. Mixed this way, Keraflex Maxi S1 has a pot life of approximately 8 hours. To achieve good adhesion, spread a thin layer of Keraflex Maxi S1 on the substrate using the straight edge of the trowel. Immediately after, apply the desired thickness of Keraflex Maxi S1 using a suitable notched trowel, depending on the type and size of the tiles. For outdoor ceramic tiling, sizes greater than 300×300 mm, floors must be subject to heavy loads, or when applying in swimming pools and basins filled with water, spread the adhesive on the back of the tile (back-buttering) in order to ensure a complete coverage.
