Kerakoll BioGel Extreme Tile Adhesive is a ready mixed, highly deformable and workable hybrid gel adhesive that bonds everything, even in the most extreme working conditions, whilst being eco friendly and suitable for use in greenbuilding. It is the two-part mix version of the popular Kerakoll BioGel No Limits Tile Adhesive.

Kerakoll BioGel Extreme Tile Adhesive comes in white, in 10kg tubs. It is a two-part adhesive, consisting of a 8.6kg pack of powder (part A) and a 1.4kg container of additive (part B).

Kerakoll BioGel Extreme Tile Adhesive has extreme adhesion qualities and is very fast bonding – it has an adhesive strength 5 times that of a class C2 (4.5 N/mm2) cement-based adhesive after 24 hours. This is partly due to its ability to fully wet the back of tiles when laid – this greatly increases the performance.

Kerakoll BioGel Extreme Tile Adhesive also features extreme deformability – 10 times more than a class S2 (>50mm) cement-based adhesive. This makes it ideal for use in stressful applications. It suffers no shrinkage and has excellent shape memory.

Kerakoll BioGel Extreme Tile Adhesive is very easy to spread – 5 times less viscous than a (35 Pa*s) polyurethane adhesive, transforms into a smooth gel like a cement based adhesive, suitable for both high and low thicknesses.

Kerakoll BioGel Extreme Tile Adhesive is also water proof, frost resistant and eco friendly – made from solvent free organic raw materials so it is non toxic and non hazardous.

Preparation & Use:

All the substrates must be flat, compact, free from with no loose flaky parts, resistant, free from any debonding agents, dust and moisture rising. It is best to apply a coat of diluted Kerakoll Primer A Eco on very absorbent cement-based substrates.

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. Packs of Kerakoll BioGel Extreme must be stored at a temperature of ≈ +20 °C for at least 2/3 days prior to use.

• Application
Kerakoll BioGel Extreme can be applied with a suitable toothed spreader, to be chosen according to the size and type of the tile. Using the smooth part of the spreader, apply a fine layer of product, pressing down onto the substrate in order to ensure maximum adhesion. Press down each tile to allow for maximum coverage of the surface.

To guarantee structural adhesion it is necessary to apply a layer of Kerakoll BioGel Extreme 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, fractionizing and perimeter joints present in the substrates.

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