Substrate Preparation:
Prioer to using Kerakoll H40 Ultimate Gel Tile Adhesive, 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 screeds must have a damp content of ≤ 0.5 % CM and be adequately sanded, cleaned using a suitable vacuum cleaner and primed.

Preparation of wood substrates: Make sure that the floor is able to bear the added weight of the tiles plus the static / dynamic service load indicated in the project. The wooden substrate must be rigid and stable and within normal levels of humidity; it may be necessary to strengthen the structure by inserting reinforcement noggings between the beams. Select appropriate plywood sheets of suitable thickness before laying the tiles with Kerakoll H40 Ultimate Gel Tile Adhesive (as indicated in BS5385-3). The plywood sheets must be screwed onto the beams with screws placed every 300 mm from the centre. The screws must be of a suitable length to ensure they fasten to the substrate, taking care not to damage anything under the floor. All sheet edges must be supported by beams or reinforcements. The surface of the sheet must be cleaned before applying Kerakoll H40 Ultimate Gel Tile Adhesive to remove any dust and debris. If the surface of the sheet has been treated in advance with fireproofing or waterproofing materials, check that the sheet is certified by the manufacturer for laying of tiles. A test should also be carried out in advance to ensure that the treatment in question does not restrict the adhesion of the adhesive itself.

Mixing: Mixing water (EN 12004-2): ≈ 20% – 22.5% by weight Mixing water on-site For low thickness laying and full wettability: ≈ 4.5 l / 1 bag on walls, for high and low thickness laying: ≈ 4 l / 1 bag The amount of water to be added, indicated on the packaging, is an approximate guide. It is possible to obtain mixtures with 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 Ultimate 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)- ≈ 40 m² in internal applications (8×5 m) with underfloor heating- ≈ 100 m² in internal applications (10×10 m) without underfloor heating- every 8 metres in long, narrow applications. Respect all structural, fractionizing and perimeter joints present in the substrates.
