Gel-Technology by Kerakoll

The researchers behind gel technology studied the behaviour of natural elements and eco-friendly raw materials and applied these to adhesives to get the perfect balance between final performance and ease of use on site.

H40 gel-adhesives

Tested for the entire life-cycle of the tiling installation.

Kerakoll researchers verify the durability of H40 gel-adhesives using the SAS method, which overcomes the limitations of the Standard by subjecting the fixed system to strain tests which simulate a floor’s life cycle.


H40 gel-adhesives encompass numerous advantages; here are their fundamental attributes.

Unique workability

Designed for the professional tile fixer making it simple to choose, easy to use and risk-free.

Superior performance

Guaranteed technical performance; subject to stringent testing which reproduces the actual conditions that a tiling installation is subjected to over its life cycle.

Actual durability

More sustainable, thanks to the use of selected innovative raw materials.

Total safety

Very low VOC emissions, non-toxic, and non-hazardous to health of fixers and end users.

The perfect gel formula

The perfect gel formula: six parameters to achieve the perfect technical balance.

The study of the perfect gel formula is based on the identification of six fundamental parameters related to the most important characteristics of workability and mechanical performance. During formulation in the laboratory, Kerakoll researchers carry out numerous tests to maximise and balance all these parameters. The perfect gel formula is created only after this long process in the laboratory and on the building site.
