Preparation of the substrate:
Prior to applying Kerakoll Setaflex Standard 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 Active Prime Fix. 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-%.
Mixing:
Mixing water ratios for Kerakoll Setaflex Standard (EN 12004-26): Grey ≈ 22% – 23% by weight, White ≈ 22% – 23% by weight
Mixing water on-site: Grey ≈ 4.4 – 4.6 ℓ/1 bag, White ≈ 4.4 – 4.6 ℓ/1 bag
The amount of water to be added to Kerakoll Setaflex Standard 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 Setaflex Standard 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.
Pre-treatment of special substrates prior to using Kerakoll Setaflex Standard Tile Adhesive: Timber (internal use only), Metal (internal use only), Gypsum and anhydrite (internal use only), PVC (internal use only): Kerakoll Active Prime Fix.
As treating special substrates is difficult to classify in a standard manner, it is always advisable to contact Kerakoll Global Service and/or request a site inspection by a GreenBuilding Consultant. In any case it is essential to carefully read the technical data sheet on how to use the indicated primers properly.
