SUREBOND-3330 Protect-A-Wall is a water-based, single component, epoxy-modified, penetrating sealer that protects retaining, concrete, block, masonry and stucco walls, as well as cultured and manufactured stone. This protective seal resists acid, salt, other corrosives and weathering, as well as discoloration from damaging UV Light. SB-3330 Protect-A-Wall also provides a moisture barrier that resists mildew, fungus and algae. SB-3330 Protect-A-Wall has the consistency of water and is milky white in appearance when applied; it dries crystal clear, creating a finish that ranges from a satin sheen to a semi-gloss depending on the surface. The product is nonhazardous and exceeds all VOC and EPA standards. It can be used indoors and outdoors on both new and old surfaces. Like all Surebond sealers, SB-3330 Protect-A-Wall can be applied immediately, as its unmatched breath ability will not trap efflorescence. SB-3330 Protect-A-Wall also seals and protects decorative, stamped and patterned concrete that has been colored with integrals, acid stains, release agents and color hardeners.
