High performance, polymer-modified, water-repellent, cement-based grout with DropEffect® technology for joints up to 6 mm CLASSIFICATION IN COMPLIANCE WITH EN 13888 Keracolor FF is an improved (2) cementitious (C) grout (G), with reduced water absorption (W) and high abrasion resistance (A), classified as CG2WA. WHERE TO USE Grouting interior and exterior floor and wall tiling (single fired, double fired, klinker, porcelain tile, etc.), stone material (natural stones, marble, granite, agglomerates, etc.), glass and marble mosaics. Some application examples • routing floor and wall ceramic tiles in interiors. G • routing swimming pools. G • routing particularly smooth and glossy floor surfaces G (smooth and polished porcelain, pre-smoothened and polished marble, glazed tiles). • routing ceramic tile industrial flooring where G resistance to chemical agents is not required (garages, warehouses, etc.). TECHNICAL CHARACTERISTICS Keracolor FF is a blend of cement, very fine-graded aggregates, special polymers, additives and pigments. The use of special hydrophobic additives (DropEffect® technology) gives grouting mortars highly waterrepellent properties, making them less prone to dirtiness and with excellent durability. The following features are obtained when mixed with the right water ratio and used correctly: • water-repellent and droplet-effect; • good compressive and flexural strength, good resistance to freeze/thaw cycles, and therefore good durability; • a smooth final surface with low water absorption, therefore easy to clean; • very good abrasion resistance; • low shrinkage, therefore absence of cracks and fissures; • good resistance to acids with pH >3; • excellent value for performance. When mixing Keracolor FF with Fugolastic, a special synthetic resin-based polymeric additive, the final characteristics are improved for use even under harsh conditions (grouting façades, swimming pools, bathrooms, floors with heavy traffic). For further information consult the Fugolastic technical data sheet. RECOMMENDATIONS • Do not mix Keracolor FF with cement or any other products. Never add water to the mixture that is beginning to set. • Do not blend different colours of grout together as there is a risk of colour inconsistency and lack of uniformity of the final shade once the grout has set. • Never mix Keracolor FF with salty or dirty water. • Use the product in temperatures between +5°C and +35°C. • he amount of mix water must be precisely measured. T Excess water could induce the appearance of a whitish coat over the surface (efflorescence). Different colour tones could result if mixtures with different water ratios are prepared. Efflorescence over the surface is due to the formation o

Grouting a glass mosaic (bathroom) with a float Finishing a glass mosaic with a sponge be caused by residual moisture contained in adhesives, not fully hydrated grouts, in substrates not adequately dried, or in substrates not adequately protected from rising damp. • After filling the joints, do not sprinkle Keracolor FF powder onto the grout as this can cause uneven colour and reduce the mechanical strength. • Expansion joints and movement joints in floors and walls should never be filled with Keracolor FF, but with the appropriate flexible MAPEI sealant. • The surface of some ceramic tiles...
