BLOK is a one-coat system which consists of a unique combination of epoxy resins and other chemical substances 2 parts A and 1 part B. It is specifically formulated to overcome the inferior adhesion properties of most resin-based systems when curing in an environment of constant wetness, extreme alkalinity (pH 13:14) and water vapor drive. Because of its extreme density it is capable of reducing water vapor and moisture to levels acceptable for most coatings, adhesives and floor covering systems. BLOK is in full compliance with current VOC regulations. has excellent chemical and abrasion resistance and is compatible with most 100% solid epoxy and/or polyurethane based materials.
FEATURES AND BENEFITS
• Excellent chemical resistance.
• Excellent flexibility to prevent hair line crack transmission to the finish floor.
• Excellent abrasion resistance.
• Compatible with most 100% solid epoxy and/or polyurethane based materials.
• Low VOC.
• When applied in black, enhance the finish of metallic epoxy surfaces.
WHERE TO USE
The primary recommended use for BLOK is to solve the problems of alkalinity and moisture/water vapor emission through mineral-based substrates such as concrete floors, floor underlayments ( not containing gypsum), screeds etc., by reducing these vapors to levels that do not interfere with the adhesion of floor coverings. It provides an excellent base coat for most coatings and adhesives that cures fast and can be used indoors due to its low odor and non-flammability. The BLOK system may be applied to concrete and other cement-based toppings that have been allowed to cure for a minimum period of 7 days. It is not pH sensitive in an alkaline environment. These unique properties allow the system to provide a solution as a base coat to pH/moisture/water vapor sensitive coatings such as polyurethane with regard to their long-term adhesion. Substrate should have a minimum compressive strength of 2500 psi.
