Kerakoll H40 Advanced Gel Tile Adhesive is a flexible, rapid setting, thixotropic tile adhesive with a gel-like consistency. It features high adhesion and deformability properties, with no slumping or slip. It is a rapid setting version of the standard Kerakoll H40 Gel Tile Adhesive, and features long workability with accelerated adhesion properties.
Kerakoll H40 Advanced Gel Tile Adhesive is suitable for use internally and externally, on 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 Advanced Gel Tile Adhesive is suitable for all types and formats of tiles and stone.
This gel tile adhesive can be used on virtually all substrates, even troublesome ones like gypsum and anhydrite, brick and block work, metal and even existing tiles.
Features and Benefits of Kerakoll H40 Advanced Gel Tile Adhesive
Kerakoll H40 Advanced Gel Tile Adhesive
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 damp content of ≤ 0.5 % CM and be adequately sanded, cleaned using a suitable vacuum cleaner and primed.
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 ≈ 20% – 23% by weight, White ≈ 28% – 30% by weight.
Mixing water on-site: For low thickness laying and full wettability: Grey ≈ 4.6 l/1 bag, White ≈ 6 l / 1 bag
On walls, for high and low thickness laying: Grey ≈ 4.1 l/1 bag, White ≈ 5.5 l / 1 bag
The amount of water to be added to Kerakoll H40 Advanced Gel Tile Adhesive, 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 Advanced 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.
Adhesive thickness: from 2 to 15mm
Temperature of the air, substrates and materials: from +5°C to +35°C
Pot life at +23°C: – grey ≈ 1 hr,- white ≈ 1 hr
Open time at +23°C: (BIII tile):- grey ≥ 45 minutes, -2- white ≥ 45 minutes
Correction Time – White and Grey: 6 minutes
Foot traffic/grouting of joints at +23°C (BIa tile): - grey ≈ 3 hrs, – white ≈ 3 hrs
Foot traffic/grouting of joints at +5°C(BIa tile): – grey ≈ 7 hrs, – white ≈ 7 hrs
Grouting in walls at +23°C (BIa tile): - grey ≈ 2 hrs, – white ≈ 2 hrs
Ready for use at +23°C / +5 °C (BIa tile): – light foot traffic ≈ 6 – 16 hrs, – heavy traffic ≈ 24 – 28 hrs, – swimming pools (+23°C) ≈ 7 days
Coverage per mm thickness: – grey (mixing ratio 23%) ≈ 1.3 kg/m2, – white (mixing ratio 28.5%) ≈ 1.2 kg/m2
