Kerakoll H40 Extreme Gel Tile Adhesive is a 2-part, rapid-setting hybrid gel tile adhesive with very high bonding strength for extreme tiling applications. It can be used in all conditions meeting the needs of all installations.

Kerakoll H40 Extreme Gel Tile Adhesive has an extremely high bonding adhesive strength of 4.5 N/mm2 which is 5 times greater than a standard C2 class cement-based adhesive after just 24 hours. It is also highly stress resistant, 10 times more deformable than a class S2 (> 50 mm) cement-based adhesive, all this guaranteeing the highest level of long-lasting performance.

This new two-part gel tile adhesive from Kerakoll is easy to spread as it is 5 times less viscous than a (35 Pa·s) polyurethane adhesive. Once spread, it transforms into a smooth gel like a cement-based adhesive. It always remains fluid and thixotropic, guaranteeing total wettability for your tiles at all times.

Kerakoll H40 Extreme Gel Tile Adhesive is suitable for both internal and external use, on both floors and walls - and can be even used for overlaying old tiles! It is suitable for use in domestic, commercial and industrial areas, such as terraces and balconies, facades, swimming pools, fountains, spas and saunas. Kerakoll H40 Extreme Gel Tile Adhesive is suitable for all types and formats of tiles and stone.

Preparation of the substrate:

All the substrates must be flat, compact, free from dust, loose particles and debonding agents and not be subject to moisture rising. It is best to apply a coat of diluted Kerakoll Primer A Eco on very absorbent cement-based substrates.

Mixing:

Single Pack: Part B is found inside the pack. Respect the preset ratio of 8.6 : 1.4. Remix part B into the bucket containing part A, being careful to mix the two parts uniformly until a smooth, even coloured mixture is obtained.

For ease of mixing and application, it is recommend to store packs of Kerakoll H40 Extreme Gel Tile Adhesive at a temperature of ≈ +20 °C for at least 2/3 days prior to use.

Application:

Kerakoll H40 Extreme can be applied with a suitable notched trowel, to be chosen according to the size and type of the tile. Using the smooth part of the trowel, apply a fine layer of product, pressing down onto the substrate in order to ensure maximum adhesion. Press down each tile into the ribbed adhesive to allow for maximum coverage of the surface.

To guarantee structural adhesion it is necessary to apply a layer of Kerakoll H40 Extreme Gel Tile Adhesive sufficient to cover the entire back of the coating material. Large, rectangular sizes with sides > 60 cm and low thickness sheets may require adhesive to be applied directly to the back of the material. Check samples to make sure the adhesive has been transferred to the back of the material.

Create elastic expansion joints:- ≈ 10 m2 in external applications (approx. 3×3 m), – ≈ 25 m² in internal applications (8×5 m), and – every 8 metres in long, narrow applications. Respect all structural, fractionizing and perimeter joints present in the substrates.
