SK-P250 VOC is a two component, low viscosity acrylic urethane. It is used as a primer/sealer over a variety of surfaces. The use of special solvents and adhesion promoters gives this material excellent penetration and adhesion to minimally profiled concrete. SK-P250 VOC is U.V. stable for use in exterior applications, cures rapidly, and is easily recoated with both solvent-based and water-based polyurethanes.
When used as a finish coat, this material gives a hard, high gloss surface that offers excellent stain resistance and easy cleanability. Compared to solvent-based acrylic sealers, SK-P250 VOC offers substantial improvements in initial gloss, gloss retention and overall performance.
SK-P250 VOC is available in a satin finish if a lower gloss is desired. A special version of this material is available to meet the 50 grams/liter VOC limit in California.
SK-P250 VOC has been designed for use over concrete, acid stained surfaces, and various types of architectural concrete. Its performance as a paver sealer is unexcelled. It is especially suitable over acid stained concrete because it is unaffected by pH drifts that can affect the adhesion of other types of primers. When used over acid stains or integrally colored concrete, it gives color enhancement similar to solvent acrylic sealers.
SK-P250 VOC can also be used as a tie coat over difficult to adhere to surfaces such as polyester urethane and solvent based acrylic sealers. When used as a finish coat in vehicle areas, it resists tire tracking and provides easy soil release. Although abrasion resistance to heavy foot traffic far exceeds single component materials, the best performance in these areas is achieved with polyester urethanes such as SK-P100, SK-P100 VOC or SK-P501.
