Description
Kerakoll Setaflex Semi-Rapid S1 White is a high-performance, semi-rapid setting flexible tile adhesive designed for the professional fixing of ceramic, porcelain and natural stone tiles. It combines a generous open time and easy workability with a controlled semi-rapid cure, allowing grouting in approximately 6 hours — a practical middle ground between standard-set and rapid-set adhesives.
Formulated to S1 deformability standards, this adhesive accommodates movement and thermal stress, making it suitable for demanding environments including underfloor heating systems, wet rooms and exterior installations. The smooth white formulation suits light-coloured or translucent tiles, helping to maintain the finished appearance without shadowing.
With excellent adhesion strength and easy application, Setaflex Semi-Rapid gives a secure bond across a wide range of substrates including sand and cement screeds, concrete, tile backer boards and prepared existing tile surfaces.
