Latex admixture imparting elasticity and enhanced adhesion to Keraquick S1 and Nivorapid WHERE TO USE • As an admixture for Keraquick S1 to obtain a high performance, fast setting, slip resistant and highly deformable adhesive (class C2FT S2 according to EN12004), for ceramic tiles and stone material. • As an admixture for Nivorapid to obtain an ultra-fast cementitious levelling compound with improved deformability and bonding strength. TECHNICAL CHARACTERISTICS Latex Plus is a water dispersion of an extremely flexible polymer with low viscosity to be mixed with Keraquick S1 or Nivorapid in order to improve their deformability improving their application and performance characteristics. RECOMMENDATIONS • Keraquick S1 or Nivorapid mixed with Latex Plus should never be applied at temperatures below +5°C or above +30°C. • Do not use more than the recommended amount of Latex Plus. • Do not add Latex Plus or water to a mix that has already begun to set. • Do not leave Latex Plus, Nivorapid and Keraquick S1 exposed to direct sunlight for long periods of time before using. APPLICATIONS A) Latex Plus + Keraquick S1 Fast setting adhesive with high deformability and no vertical slip for interior and exterior installations of ceramic tiles and stone material. B) Latex Plus + Nivorapid Fast setting levelling compound with high deformability for interior surfaces. A) LATEX PLUS + Keraquick S1 WHERE TO USE Interior and exterior installations of ceramic tiles (double-fired, single-fired, gres, clinker, terracotta, vitreous mosaic, porcelain, etc.), including large format, and moisture-stable natural stones not subject to staining on: • underfloor heating installations; • fagades, balconies, terraces; • precast concrete walls; • existing floors (ceramic tiles, marble, etc.); • cement screeds or hot-poured asphalt substrates (provided they are stable and well oxidized); • deformable surfaces (gypsum board panels, asbestos cement, etc.). APPLICATION PROCEDURE Preparing the substrate Substrates must be flat, mechanically strong, free of loose debris, grease, oil, paint, wax etc. and sufficiently dry. Damp substrates could slow the setting of Keraquick S1 + Latex Plus. Cementitious substrates must not continue to shrink once the tiles have been installed, therefore renders should be cured at least 2 weeks. Cementitious screeds must have an overall cure of at least 3-4 weeks unless they have been made with the special MAPEI binders for screeds such as Mapecem, Mapecem Pronto, Topcem or Topcem Pronto. Surfaces that are too hot due to exposure to direct sunlight should be dampened with water. Gypsum substrates and anhydrite screeds must be perfectly dry (maximum residual moisture 0.5%), sufficiently hard and free from dust. They must be treated with Primer G or Eco Prim T.

Mixing ratios Mix Keraquick S1 with Latex Plus only, without adding water, when maximum deformability is required, e.g. for tiling directly over poured concrete with at least 3 months curing in favourable atmospheric conditions, for large size ceramic tiles (> 30x30 cm), or installations subject to wide temperature fluctuation. 6 kg of Latex Plus for each 20 kg bag of Keraquick SI Grey; 6 kg of Latex Plus for each 20 kg bag of Keraquick SI White. Preparing the mix Pour the powder into the liquid, mixing with an agitator at low speed until a homogenous, lump-free paste is obtained. Let the...
