Seal Once Nano-poly Concrete and Masonry has been leading the innovation in the use of nano-particle technology. Using this technology to create long-lasting, Eco-friendly wood sealers and also tinted wood and masonry products since 2005.  Our Concrete and Masonry Waterproofing Sealer is water-based, ultra-low VOC & engineered to penetrate even dense material such as concrete and masonry.

Unlike most top-coat sealers on the market today, Seal Once Nano-Poly Concrete and Masonry penetrates deep below the surface to form a long-lasting water-resistant shield around the concrete and masonry surface.  The added POLY creates a surface coating for superior abrasion resistance in high-traffic areas that make it a great choice for protecting any concrete and masonry such as patios. This clear formula will not alter the natural color of the concrete or masonry.

Concrete and Masonry has none of the toxic chemicals common in oil & solvent based wood sealers & stains, so it can be applied safely around homes, landscaping & vegetation.  SEAL-ONCE is warranted to prevent long-standing water accumulation for up to 10 years on vertical & 6 years on horizontal surfaces.
