SB-3330 Protect-A-Wall is a water-based, single component, acrylic co-polymer sealer specially formulated with an antifungal designed to help inhibit growth of mold, moss and algae on the sealer film when applied on vertical hardscape surfaces. SB-3330 protects surfaces from salts, acids and other corrosive chemicals as well as help to minimize overall surface weathering and deterioration. SB-3330 has the consistency of water and is milky white in appearance when applied and dries clear, creating an enhanced look with semi-gloss finish. SB-3330 is non-hazardous and VOC/EPA compliant. It can be used indoors and outdoors on both new and old surfaces. SB-3330 can be applied immediately, as its unmatched breathability will not trap efflorescence. SB-3330 is a single application product. Cured sealer is freeze resistant to -60°F (-51°C) and is stable up to a temperature of 180°F (82°C).

SB-3330 Helpful Information


TEST FIRST on a small inconspicuous area to determine the suitability and if desired results are achievable with this product on your specific surface. The surface should be thoroughly clean and free from oil, dust, loose material, and previously applied sealer other than SB-3330 prior to sealer application. If needed, prepare surface with Surebond Cleaners before sealing. Thoroughly rinse all cleaner residue prior to sealing. Allow the surface to dry for a minimum of 24 hours after cleaning and/or rain before sealer application. A leaf blower is recommended to remove dust, debris and fine sand particles from the surface. Cover/protect nearby landscape, vehicles, and buildings from overspray during application.


Apply when day and night temperatures are between 40°F – 95°F. Avoid windy conditions to keep sealer spray from drifting. NO pre-blending or mixing required. Do NOT dilute. SB-3330 should be liberally and evenly applied to the surface with a siphon pump, bulk sprayer or a hand-held garden sprayer. Use product coverage guidelines to determine the amount of material required for the project; material coverage will depend on the surface type and its porosity. Saturate the surface to ensure proper penetration. Use a foam roller to insure uniform coverage of sealer over the entire surface area and to remove all excess sealer from the surface. SB-3330 is a single application product. Re-applications may need to be carried out every 3-5 years depending on exposure. NOTE: Excessive applications can cause surface to become slippery. Application of this product is out of the control of SEK-Surebond. Application steps should be followed completely and accurately.
