Discontinued Surebond SB-7700 is the same product.

SB-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 breathability 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.


Prior to application, remove all curing compounds or visible signs of staining and efflorescence with SB-442 General Stain Remover or SB-488 Efflorescence & Rust Remover. The wall surface should be clean and free from oil, dust and any loose material. Remove blistering, peeling or flaking paint, loose and damaged stucco, as well as damaged mortar between masonry and stone units. Use a chlorine or bleach based cleaner to remove mildew, fungus or algae prior to application to kill growth. Additional heat may be needed to facilitate sufficient drying prior to application. Allow the surface to dry completely.

Application Information:

SB-3330 Protect-A-Wall should be liberally and evenly applied to the wall surface with a siphon pump, bulk sprayer or a hand-held garden sprayer. Use coverage guidelines to determine the correct amount of material for the project; material coverage will depend on the surface type and its porosity. Saturate the surface to ensure proper penetration and use a heavy nap or sponge roller to facilitate a complete seal. Remove any excess material from the wall with a paint roller.

Coverage Per Gallon:

100-200 square feet depending on substrate porosity.
