Kerakoll H40 Gel Adhesive S1 20kg White

Kerakoll H40 Gel Adhesive is a high-performance S1 deformable flexible tile adhesive designed for fixing porcelain, ceramic and natural stone tiles. Its advanced gel technology provides enhanced workability, improved coverage and excellent bond strength, making it ideal for professional tilers working with modern large format and low-absorption tiles.

Formulated to deliver reliable performance in both internal and external applications, Kerakoll H40 Gel offers reduced vertical slip, extended open time and excellent flexibility. This makes it particularly suitable for demanding installations such as large format porcelain, floor tiling, and areas with underfloor heating systems.

The S1 classification ensures deformability, allowing the adhesive to accommodate minor substrate movement without compromising bond integrity. Whether installing on concrete screeds, cement-based substrates or tile backer boards, Kerakoll H40 Gel provides strong, consistent adhesion.
