DESCRIPTION: FK-4 Extreme is a high-performance micro/nano dispersion, impregnation water-repellent and oil-retardant that provides a high level of in-depth action and resistance to alkalinity, with BioFilmStop micro-organism inhibition technology, providing a colourless finish that does not alter the tone of the surface. A solution based on silanes, siloxanes and innovative C6 modified fluorinated compounds, free of PFOA and PFOS. Provides protection against surface deterioration resulting from water absorption, also and against the adherence of dirt and grime. Provides colourless, oil-retardant and water-repellent conservation and protection on the vast majority of absorbent mineral material surfaces, both interior and exterior, particularly on low-porosity surfaces. Does not form a film as it penetrates into the pores of the base material, providing long term protection against pollution dissolved in water, frost deterioration and the spread of micro-organisms, inhibiting the in-depth adherence of dirt and grime and facilitating both cleaning and maintenance work. Does not result in significant physical changes to the treated surface, particularly in terms of breathability (Value SD = 0.10). The oil-retardant properties will not appear until 24 hours have passed. Unlike some varnishes, following application and once dry, FK-4 Extreme will not alter the inflammable qualities of the mineral bases onto which it has been applied and will act as a flame retardant. FK-4 Extreme does not form a film, and has been designed to notably improve the qualities of resistance to water, oils grime and dirt, facilitating maintenance and extending useful life.
MAIN USE: FK-4 Extreme is ideal for all manner of absorbent natural and artificial stone, and particularly useful in cases of low porosity, such as marble, granite, travertine or micro-cements, and also for other mortars and concretes, even when recently set and with high levels of alkalinity, mineral paints and coatings, refractory, clinker, exposed, roof tiles, lime stucco and similar; earthenware floor and absorbent ceramic tiles, swimming pool copings, slates, etc. Mainly for use on façades, heritage work, flooring tiles, theming, civil engineering, industry in general, the food industry, housing, hotels, skirting boards, tourist establishments, public squares, chalets, restaurants, kitchens, washrooms, etc. (Not suitable for direct contact with foods)
SOLVENT THINNING: It is recommended that the product be applied undiluted to provide maximum protection, mainly on floors, marble work surfaces, etc., or in solutions of 1:1, combined with FK-45 Solvent, for generalised water proofing of façades and similar.
HOW TO APPLY: Carefully protect all surfaces that are not to be treated from splashing and ensure that interiors are well ventilated. Following suitable preparation of the base, and on dry surfaces, apply FK-4 Extreme 2 or 3 times in a row using brushes, rollers or spray guns, each time on top of the previous coat while it is still wet, and always working from the bottom up. Clean utensils immediately after use with a solvent. Only apply the quantity that can be absorbed by the surface to be covered and avoid applications that leave excess remains of the product on the surface. Where necessary eliminate any excess product applied using a rag before it can dry, as it will leave yellowish stains if this is not done. Any splashes or dry remains on surfaces will have to be eliminated as quickly as possible using solvent. Will resist rain 24 hours after application, although the full water-repellent affect does not occur until several days have passed. For more information consult the specifications sheet and/or application guidelines, along with the safety sheet.
AVERAGE YIELD: FK-4 Extreme, when undiluted, provides an average yield of 3-10 litre/m², and when diluted 1:1 with the solvent indicated on the label, of 6-20 m² per litre of pure product.
