5.00 out of 5 based on 1 customer rating
(1 customer review)

SEAL-ONCE® NANO+POLYTM Concrete and Masonry Sealer combines our proprietary nanotechnology 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+POLYTM 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.

NANO+POLYTM stops water from leaching out natural salts in concrete, preventing efflorescence.

NANO+POLYTM is a water based, ultra-low VOC, non-toxic, odorless formula. It can be applied around landscaping and other vegetation without causing damage.

Surfaces that have been treated with SEAL-ONCE® NANO+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+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+POLY.

Surfaces can be recoated with NANO+POLY at any time. NANO+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+POLY, clean the surface using the recommended cleaning solution above. Apply NANO+POLY according to package instructions. When reapplying in small areas, lightly overlap onto areas previously treated with NANO+POLY.
