All You Need To Know About The Kerakoll H40 Adhesive Range

Kerakoll H40 Gel Tile Adhesive – Instructions for use:
Preparation of the substrate:
Substrates must comply with BS 5385, parts 1-5, be level, cured, undamaged, compact, rigid, dry and free from any debonding agents. It is good practice to dampen highly absorbent concrete substrates or apply a coat of Kerakoll Primer A Eco. Anhydrite substrates must have a residual humidity ≤ 0,5 CM-%. Cement-based screeds must have a residual humidity ≤ 2 CM-%. Anchored substrates must comply with BS 8204 and anhydrite with underfloor heating must have a residual humidity ≤ 0,3 CM-%.

Please note: For pre-treatment of internal special substrates such as metal, timber, PVC, asphalt/bitumen, gypsum and anhydrite, prime with Kerakoll Keragrip Eco Primer.

Mixing:
Mixing water (EN 12004-26): Grey ≈ 23% – 29% by weight, White ≈ 26% – 33% by weight.
Mixing water on-site: For low thickness laying and full wettability: Grey ≈ 5.7 l/1 bag, White ≈ 6.6 l / 1 bag
On walls, for high and low thickness laying: Grey ≈ 4.5 l/1 bag, White ≈ 5.1 l / 1 bag

The amount of water to be added to Kerakoll H40 Gel Tile Adhesive, indicated on the packaging, is an approximate guide. It is possible to obtain mixtures with the consistency of variable thixotropy according to the application to be made.

Application:
To guarantee structural adhesion it is necessary to apply a layer of Kerakoll H40 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.

Kerakoll H40 Extreme Gel Tile Adhesive – Instructions for use:
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. Applying a coat of diluted Kerakoll Primer A Eco on very absorbent cement-based substrates is best.

Please note: For pre-treatment of internal special substrates such as sheet metal, metal, timber, rubber floors and PVC, clean with Kerakoll Keragrip Eco Pulep.

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, carefully mixing 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 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.

Clean the tools and any residues of Kerakoll H40 Extreme from the coated surfaces with water while the adhesive is still fresh. Once hardened, the adhesive can only be removed mechanically or using Kerakoll Fuga Shock Eco cleaner.
