FK-7 (CE Marking)

DESCRIPTION: FAKOLITH FK-7 is a concentrated, water-miscible, consolidating water-repellent, micro/nano dispersion, with CE Marking test data, effective against micro-organisms, with penetrating action, colourless and highly breathable. Provides effective protection against environmental influences and the causes and consequences of dampness in absorbent construction materials. The micro/nano dispersion of the FK-7 modified nano silane-siloxanes results in a “dew-drops” water-repellent effect. Once dissolved in potable water the mix is low voc and reacts with the construction element to which it has been applied, producing a water-resistant area, while at the same time allowing for the complete dispersion of water vapour (SD = 0.02), presenting excellent resistance to environmental influences and UV rays. Due to its high level of breathability FK-7 will not compromise the correct curing of the base material. Stable with regard to meteorological changes it rejects dirt and grime. Protects against harmful, hygroscopic salt bloom on construction elements and counteracts the appearance of damp patches originating inside walls. Another important function is that it highlights and maintains the natural colours of the surfaces it is applied to. Activates transpiration by drying damp patches and, due to its BioFilmStop technology, FK-7 is also highly resistant to mould and algae. Can be applied to damp surfaces, as it transmits through water. Particularly recommended for concrete structures where, due to its penetrability and protection against damp, it protects by inhibiting corrosion of the internal rebar-reinforcing, in this way prolonging useful life.

BIOFILMSTOP SANITARY TECHNOLOGY: FK-7 is an intelligent water-repellent, treated with BioFilmStop Inhibition Technology, and highly resistant to mould and microorganisms, DIN-UNE EN 15457:2008 ((Aspergillus, Cladosporium, Penicillium, Algae…), as well as bacteria ISO 22196:2011. The products in the BioFilmStop range positively contribute to compliance with (EC) 852/2004, and are manufactured subject to HACCP and GMP (EC) 2023/2006, also notably improving HACCP, food safety and asepsis for the user company. Declaration of Conformity – Health Register FAKOLITH RGSEAA ES-39.005259/T y ROESP E-0043-E.

MAIN USE: FAKOLITH FK-7 is ideal for the waterproofing, conservation, drying and strengthening of almost all porous or absorbent mineral materials, such as natural and artificial stone, concrete, mineral based paints and coatings, absorbent ceramics; and also for wood, interior or exterior and subject to a wide range of climactic conditions, principally on vertical wall surfaces and façades. FK-7 is the ideal water-repellent for restoration processes on surfaces suffering from damp pathologies. Apt for application in drilled rising damp treatments, request additional information. Mainly for use on façades and for rehabilitation, heritage projects, theming, civil engineering, industry in general, the food industry, etc. Limitations: Any type of polished base that lacks capacity for absorption (in these cases use FK-4 Extreme). Extremely alkaline, white or fresh cement bases (in these cases use FK-3 Plus N). Interior or exterior natural stone bases with water lixiviation with surface creep (limited function).

WATER THINNING: Generally speaking concentrated FK-7 should be diluted at a ratio of 1:14. For bases with rising damp, in order to enhance the natural colour of the mineral surface, and also in the case of woods, dilute using potable water, at a ratio of 1:9. Solely mix the quantity that you will be using during the day, given that the mix will only remain stable for around 8-12 hours and should not be used once that time has elapsed.

HOW TO APPLY: Carefully protect all surfaces that are not to be treated from splashing. Following suitable preparation of the surface, apply FK-7 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. Make sure you clean all utensils immediately after use with water. Only apply the quantity that can be absorbed by the surface to be covered and avoid applications that will leave excess product on the surface. Will resist rain 24 hours after application, although the full water-repellent affect does not occur until several days have passed. Applicable at temperatures of 2-3ºC or over. For more information consult the specifications sheet and/or application guidelines, along with the safety sheet.

AVERAGE YIELD: FK-7, when undiluted, provides a yield of approx. 20-60 litres/m², although this may vary considerably depending on type of surface and method of application. Average consumption in solution is approx. 250 ml/m², although this may also vary between 100 and 500 ml/m².
