Larsen S1 Flexible Standard Adhesive (White)

The Larsen Professional Fibreflex™ S1 Flexible adhesive is a specially formulated, high-performance cement-based adhesive designed to meet the demanding needs of both professional tilers and DIY enthusiasts. Its advanced formulation ensures superior bonding for a wide range of tiling and flooring applications, making it an ideal choice for residential and commercial settings where a standard setting time is preferred. Specialized for use with light-coloured stones and mosaics, the white formulation prevents shadowing through translucent tiles.

Why Choose Larsen Fibreflex™ S1 Flexible?

• Specialized S1 Flexibility: Engineered with advanced polymers to provide excellent flexibility, this adhesive is prioritized for use on challenging surfaces such as heated screeds and overboarded timber, accommodating slight movements without compromising the bond.

• Extended Working Time: Unlike rapid-set alternatives, the standard set formulation is optimized to give the installer more time to adjust tiles, making it specialized for intricate patterns, large-format tiles, or complex layouts.

• High-Grab Non-Slip Technology: Formulated for professional wall and floor tiling, the high-grab consistency ensures that even heavy porcelain and natural stone tiles remain securely in place during installation.

• Specialized White Formulation: The brilliant white colour is prioritized for fixing light-coloured marble, limestone, glass, and mosaic tiles, ensuring the adhesive does not discolour or show through the tile surface.

• Versatile Substrate Compatibility: Optimized for the most demanding environments, it is ideal for installations involving underfloor heating systems, swimming pools, and both interior and exterior walls or floors.

• Industry Certified Quality: Fully complies with BS EN 12004 standards, ensuring a high-strength, durable bond that meets rigorous professional tiling requirements for long-term reliability.
