Kerakoll H40 Gel Adhesive S1 20kg Grey

Kerakoll H40 Gel Adhesive S1 20kg Grey

Kerakoll H40 Gel Adhesive S1 20kg Grey is a high-performance flexible tile adhesive engineered for fixing porcelain, ceramic and natural stone tiles. Its innovative gel formulation enhances workability and coverage, allowing for smooth application and reliable adhesion across a wide range of substrates.

Designed to meet S1 deformability standards, Kerakoll H40 Gel accommodates minor movement within the substrate, making it suitable for modern tiling installations including large format porcelain tiles and areas with underfloor heating systems. The adhesive delivers high bond strength with reduced vertical slip, giving installers greater control during application.

The grey formulation is particularly suitable for darker tiles and natural stone where colour consistency is important. Suitable for both internal and external use, Kerakoll H40 Gel performs reliably on floors and walls in residential and commercial settings.
