Dunlop CF-24 Flexible Tile Adhesive is a new slow-set tile adhesive with reduced slip and extended open time for those difficult tiling jobs, or tiling jobs in hot or humid conditions. Available in Grey and White, it has a pot life of 5 hours and an open time of 30 minutes on the wall or floor. Grout in 24 hours. Water resistant, it can be used internally or externally in dry or wet areas (tank with an appropriate waterproofing system). Because it is flexible it is perfect for use with underfloor or undertile heating systems where encased with a levelling compound.
