Buy Tile Adhesive & Kerakoll H40 Extreme 2 Part Hybrid Gel Adhesive White 10kg Full Pallet (33 Tubs Tail Lift) Online

Full Pallet 33 x 10kg Tubs

Highly deformable and workable hybrid gel-adhesive tested for extreme conditions and uses.

Very fast bonding. Adhesive strength (4.5 N/mm²) 5 times superior to a class C2 cement-based adhesive after 24 hours.
Stress resistant. 10 times more deformable than a class S2 (> 50mm) cement-based adhesive.
Easy to spread. 5 times less viscous than a (35 Pa·s) polyurethane adhesive, transforms into a smooth gel like a cement-based adhesive.

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 Primer A Eco on very absorbent cement-based substrates.

Adhesive preparation:
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 recommended to store packs of H40 Extreme at a temperature of ≈ +20 °C for at least 2/3 days prior to use.

Application:
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 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,
- ≈ 25 m²
 in internal applications,
- every 8 metres in long, narrow applications. Respect all structural, fractionalizing and perimeter joints present in the substrates.
