Stain Block Elite

Stain Block Elite Stain Block Elite is a state-of-the-art penetrating sealer that is equally effective on porous and dense surfaces such as concrete, natural stone and masonry. Product Information Stain Block Elite is a state of the art, water and stain resistant, penetrating fluoropolymer impregnating sealer. It has been specifically designed for porous to dense concrete, brick, natural and manufactured stone surfaces. When dry it is virtually invisible, leaving the surface with its original appearance and breathability. It resists oil and grease stains, rust stains, moss, mildew and spalling problems associated with freeze/thaw cycles. Stain Block Elite provides superior protection against moisture penetration, thereby reducing the formation of efflorescence. Stain Block Elite chemically bonds with the silicates present in the surface, forming an insoluble barrier that will not fade, yellow, crack or peel. It is highly alkaline resistant and designed for use on dense surfaces
