PROFLEX® MB25 is a two component, epoxy reaction resin based sealer for professional flooring installation over damp sub floors. MB25 will mitigate moisture pressure up to 25 lbs. Per 1000 sq. ft. per 24 hours and in-situ Relative Humidity (RH) moisture readings up to 100%. It will bridge minor cracks in the subfloor. MB-25 spreads easily and creates a dust free surface ready for safe installation of flooring.
PROFLEX® MS-225 Moisture Sealer is a unique one-part, multi-functional moisture barrier that dries to a clear film that is alkali and water-resistant. It is designed for use on interior porous concrete substrates as a penetrating and film-forming hydrophobic (water repelling) barrier to protect flooring installations against moisture vapor transmission rates of up to 15 lbs. Per 1000 sq. ft. per 24 hours and in-situ Relative Humidity (RH) moisture readings up to 95%. The multi-functionality of the product results from the barrier coating ability to prime porous concrete and eliminate dust, and to neutralize surface alkalinity by forming a barrier coating that provides an acceptable pH level and block migration of alkaline salts through the slab.)
