Description
UltraTile ProFlex SPES Standard Set Flexible Tile Adhesive in Grey is a single-part, polymer-modified S1 flexible adhesive formulated for professional tilers who need reliable bonding with a genuinely long working time. Classified C2TE S1 to EN 12004 and EN 12002, it delivers the deformability and enhanced adhesion needed for demanding wall and floor tiling projects, including underfloor heating installations and substrates subject to slight movement.
Key Benefits
ProFlex SPES combines an extended pot life with dependable early grab, giving tilers the confidence to work methodically without adhesive skinning over. Its S1 flexibility rating means it accommodates minor structural movement and thermal expansion far better than standard C2 adhesives, reducing the risk of tile debonding or cracking over time. Backed by a 25-year guarantee, it is a trusted choice for both domestic and commercial specifications.
Applications
Suitable for fixing porcelain, ceramic, mosaic, natural stone and glass tiles to walls and floors, internally and externally. ProFlex SPES Grey performs reliably over timber floors requiring flexibility, swimming pool surrounds, and underfloor heating systems, making it a genuinely versatile, one-bag solution for most trade tiling applications.
