SEAL-ONCE® NANO GUARDTM PLUS POLY Concrete and Masonry Sealer combines our proprietary nano-polymer formula with the strength of polyurethane to provide 360° of protection. Its flexible barrier prevents concrete, brick and masonry deterioration caused by water intrusion.

Our NANO GUARD PLUS POLY comes in a clear matte finish that will not alter the original appearance of concrete, brick or masonry, will not yellow over time, and will not add a sheen to the surface, making it slick or slippery.

The addition of our high-quality, long-lasting water based polyurethane provides abrasion and UV-resistance, protecting your concrete and masonry from weathering, scuffs and scratches, in addition to preventing water damage.

NANO GUARD PLUS POLY stops water from leaching out natural salts in concrete, preventing efflorescence. It is also chemical resistant, protecting concrete from harsh chemicals such as chlorine.

NANO GUARD PLUS POLY is a water based, low VOC, non-toxic, low odor formula that can be applied around landscaping, vegetation or around water without causing damage.

Surfaces that have been treated with SEAL-ONCE® NANO GUARDTM PLUS POLY can be cleaned using a mixture of 1 gallon warm water, 14 oz. bleach, and 1 oz. of Dawn® dish detergent. Apply this cleaning solution with a sprayer and allow to sit for 20 to 30 minutes on the surface before rinsing with water using a garden hose with a nozzle.

This cleaning solution can be used to remove airborne mold and mildew stains, dirt and grime from the surface. NANO GUARD PLUS POLY will prevent and resist any water, mold and mildew penetration. Do not use oxidizers, corrosives or strippers on surfaces that have been treated with NANO GUARD PLUS POLY.

Surfaces can be recoated with NANO GUARD PLUS POLY at any time. NANO GUARD PLUS POLY may need to be reapplied for fading tint color, surface damage, in heavily worn or high traffic areas, or in places where the surface may have undergone noticeable changes.

Before reapplying NANO GUARD PLUS POLY, clean the surface using the recommended cleaning solution above. Apply NANO GUARD PLUS POLY according to package instructions. When reapplying in small areas, lightly overlap onto areas previously treated with NANO GUARD PLUS POLY.
