How to use Kerakoll H40 Gel Tile Adhesive

How to prepare your substrates for tiling

The surface you want to tile onto must be level, cured, undamaged, compact, rigid, dry and free from any debonding agents or anything that might react with the adhesive. Kerakoll recommend that you dampen highly absorbent concrete substrates or apply a coat of Kerakoll Primer A Eco to ensure bond strength. Anhydrite substrates must have a residual humidity below or equal to 0,5 CM-%. Cement-based screeds must have a residual humidity below or equal to 2 CM-%. Substrates must comply with BS 5385 parts 1-5. Anchored substrates must comply with BS 8204 and anhydrite with underfloor heating must have a residual humidity below or equal to 0,3 CM-%.

Please note: Some substrates such as metal, timber, PVC, asphalt/bitumen, gypsum and anhydrite require pre-treating before the applying Kerakoll H40. You should prime these substrates with Kerakoll Keragrip Eco Primer.

Mixing:

You should always mix tile adhesive following the directions on the packet. Kerakoll H40 should be mixed with water: Grey ≈ 23% – 29% by weight, White ≈ 26% – 33% by weight.

Mixing water on-site: For lower thickness laying and full wettability: Grey ≈ 5.7 l/1 bag, White ≈ 6.6 l / 1 bag. On walls, for higher and lower thickness laying: Grey ≈ 4.5 l/1 bag, White ≈ 5.1 l / 1 bag.

As with any tile adhesive, the amount of water to be added to Kerakoll H40 Gel Tile Adhesive when mixing is always an approximate guide. You may need to vary the amounts of water to obtain mixtures with consistency of variable thixotropy according to the application you need.

Application:

In order to guarantee adhesion it is necessary to apply a layer of Kerakoll H40 Gel Tile Adhesive to cover the entire back of the tiles and coating material. Large, rectangular sizes with sides larger than 60cm and low thickness sheets may require adhesive to be applied directly to the back of the material. Always do a small area first as a sample to make sure the adhesive has been transferred from your substrate to the back of the material.
