Description
Kerakoll H40 Gel Adhesive Standard Set S1 in White is a multipurpose, structural tile adhesive engineered by Kerakoll in Italy and built around their proprietary Gel-Adhesive technology. The result is a single adhesive that behaves as both a thixotropic paste and a fluid-bed mortar — giving the tiler full back-buttering coverage on large-format tiles while remaining non-slump on vertical applications.
The white formulation is the specifier's choice for installations where adhesive bleed-through the joint would discolour grout or show through translucent tile material. Light-coloured porcelain, polished marble, translucent natural stone, glass mosaic and any tile where light passes through the body or grout line all benefit from a white-bed adhesive — the visible joint stays clean and the finished surface keeps its intended tone.
Classified C2TE S1 to European standard, H40 Gel delivers the deformability required for the most demanding substrates: underfloor heating systems, anhydrite screeds, timber-based subfloors and external terraces all sit comfortably within its specification. The extended open time and generous pot life give installers the working window needed for large-format porcelain installation without the risk of skinning between trowel-out and tile placement.
Built on Kerakoll's premium-trade specification standards, H40 Gel sits at the heavy-end of the trade adhesive market — the right specification for tilers and contractors working to architect-specified build-ups and high-spec commercial installations.
