UltraTile ProRapid RS Flexible Rapid Tile Adhesive 20kg is a single-part, rapid-setting, premium-grade cementitious tile adhesive perfect for installing wall and floor tiles. It's ideal for effective bonding upon ceramic, porcelain, and natural stone tiles, making it suitable for a wide range of building projects, including floors, walls, underfloor heating, and projects both internal and external. This solution is formulated to adhere to most common surfaces and substrates, such as concrete, sand/cement screed, plywood overlay (minimum 15mm), tile backer boards, cement-faced fibre boards, anhydrite/calcium sulphate/gypsum-based screeds, tile on tile (pre-existing ceramic, porcelain, or natural stone tiles, known as 'tile on tile'), firm and stable plaster, plasterboard, sand/cement render, and concrete brick/block. The adhesive can take light foot traffic within 3 hours of installation, depending on temperature and substrate.
