4G SURFACE GUARD (WALLS) is a durable and long lasting penetrating sealer for porous, brick, stone, masonry, concrete, clay, and other mineral surfaces. Designed to provide maximum graffiti resistance and prevent longer term deterioration from pollution, acid rain, smog, salt, water penetration, efflorescence, and damage caused by freeze/thaw cycle. Removing all types of stains including moss, algae, and lichens is much easier on the protected substrate. Permanent stains and damage from high pressure cleaning is avoided, preserving the natural appearance of walls, and greatly reducing cleaning and maintenance costs.
4G SURFACE GUARD is composed of a specially formulated blend of halogenated methacrylic micro co-polymers which effectively repels moisture and liquid-based pigments and grime, inhibiting it from absorbing into the porous substrate and bonding with the surface materials. 4G SURFACE GUARD is not film-forming but rather penetrates into porous substrates through their natural absorbency creating a microscopic high density molecular protective network below the surface. As a result, the substrate remains vapor permeable and the final finish is largely invisible. Under normal conditions, 4G SURFACE GUARD performs for 10 years or longer, and can be easily revitalized by reapplying as needed without stripping the original coat.
4G SURFACE GUARD works brilliantly in conjunction with WORLD'S BEST GRAFFITI REMOVAL PRODUCTS.
