About the product

One bag for large format, underfloor heating, and difficult substrates

Kerakoll H40 Gel-Structural Adhesive is the brand's benchmark adhesive for demanding ceramic installations. Its gel technology combines high adhesion and deformability with a very practical feature: variable rheology. The same product can be mixed to be thixotropic or fluid depending on the requirements of the job, which avoids having to store two different references.

FOR LARGE FORMAT, DOUBLE BONDING: For large and low-absorption pieces, both the substrate and the back of the tile must be glued. This is the only way to ensure 100% contact and avoid gaps that later cause breakages.

Why choose H40

  • Variable rheology: thixotropic for vertical, fluid for large format. One product.
  • High deformability: absorbs thermal movements of underfloor heating without detaching the piece.
  • Suitable for large format and low-absorption pieces, where standard adhesives fail.
  • Compatible with leveling systems (spacers and wedges), without subsequent settlements.
  • Reliable on difficult substrates where high adhesion and flexibility are required.
  • Available in white and gray, to choose according to joint color and material.

Technical data sheet

Type Gel-structural adhesive with gel technology
Rheology Thixotropic and/or fluid (adjustable in mixing)
Compatibility Porcelain, ceramic, and natural stone
Colors White (R.M. 30%) and gray (R.M. 25%)
Yield Approx. 1.25 kg/m² per mm of thickness
Packaging 20 kg bags
Storage Approx. 12 months in original closed and dry packaging

Actual consumption depends on the tile format, type of substrate, and trowel notch. For double bonding, expect significantly higher consumption.

Where it is used

Installation of porcelain stoneware, ceramic, and natural stone of any type and format; installations with large format and low absorption pieces; underfloor heating and areas with thermal variations; and works on difficult substrates requiring high adhesion and flexibility.

How to apply

  1. Check that the substrate is clean, cohesive, dry, and within flatness tolerances.
  2. Mix according to the technical data sheet until the desired rheology is achieved, thixotropic or fluid depending on the job.
  3. Spread with a notched trowel suitable for the format. Double bonding is mandatory for large formats.
  4. Set the tile with pressure movements, check joints and flatness, and install the leveling system.
  5. Respect the open, adjustment, and grouting times indicated by the manufacturer.
