It is good practice to dampen highly absorbent concrete substrates or apply a coat of Kerakoll Primer A Eco. 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-%.PreparationMixing water (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, 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.ApplicationTo guarantee structural adhesion it is necessary to apply a layer of 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) withunderfloor 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.NotesPre-treatment of special substratesTimber (internal use only): Keragrip Eco Metal (internal use only): Keragrip Eco Gypsum and anhydrite (internal use only): Primer A Eco PVC (internal use only): Keragrip Eco 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.Materials and special substratesNatural stones and recomposed materials: materials that are known to be subject to deformation or staining due to water absorption require a quick-setting or reactive adhesive.Natural stone in general may have characteristics that vary even with reference to materials of the same chemical and physical nature. For this reason it is essential you consult Kerakoll Global Service to request specific indications or to carry out a test on a sample of the material.In the absence of specific indications from the manufacturer, natural stone slabs with reinforcement layers, in the form of resin coating, polymer mesh, matting, etc. or treatments (for example damp courses, etc.) applied on the laying surface must be tested in advance to ensure they are compatible with the adhesive. Check for the presence of any really consistent traces of rock dust created during cutting, and remove them if found.Waterproofing products: adherent and floating polymer sheets, liquid bitumen and tar-based sheets or membranes require application of a laying screed on top. In the case of reactive waterproofing products (such as RM waterproofing according to EN 14891) it is necessary to use a reactive adhesive.Kerakoll Setaflex Semi-Rapid technical dataShelf life≈ 12 months from production in the original sealed packaging, protect from humidityPack20 kgAdhesive thicknessfrom 2 to 12 mmTemperature of the air, substrates and materialsfrom 5 °C to 35 °CPot life at 23 °C- grey≈ 90 - 120 min.- white≈ 90 - 120 min.Open time at 23 °C (BIII tile):- grey≥ 45 min.
