Kelmore’s MoreFlex Semi-Rapid S1 is a highly polymer modified, flexible, semi-rapid setting, cementitious tile adhesive for walls and floors. This deformable adhesive has excellent bond strength and flexibility ensuring numerous types of tiles, such as porcelain, ceramic, and natural stone can be confidently fixed to a wide range of backgrounds, including underfloor heating systems and those subject to limited movement and vibration. Allowing bed depths up to 15mm, MoreFlex Semi-Rapid S1 has a pot life of 2 hours, an open time of 30 minutes and is set and ready for grouting after 6 hours – making it the perfect choice for projects when the working and set times of rapid and standard setting products don’t meet your requirements. MoreFlex Semi-Rapid S1 is suitable for interior and exterior use, as well as in wet areas, including swimming pools, and it is particularly recommended for fixing large format tiles.
