Water-Based Penetrant/Weather Barrier For Horizontal Masonry, Concrete, Brick and Stone

ENESEAL MP/HS is a single component, water-based, ultra-low viscosity weather barrier which dries to a completely invisible, water repellent masonry sealer. It provides extraordinary weather protection to virtually all types of concrete, masonry and mineral surfaces.

ENESEAL MP/HS forms a hydrophobic barrier inside masonry pores that repels water and water-borne salts. This significantly reduces the damaging effects of moisture penetration into concrete and masonry, such as surface scaling, freeze-thaw cracking and corrosion of reinforcing steel.

The invisible barrier forms below masonry surfaces to depths of up to 3/4 inch and, therefore, will not wear away as a result of surface traffic and/or harsh weather conditions. This barrier is also breathable – allowing water vapor to escape from inside the concrete or masonry while dramatically reducing liquid water penetration into the substrate.
