LastiSeal Brick & Concrete Sealer | FLAT

State-of-the-art penetrating sealer that waterproofs and hardens surfaces. Unmatched performance and durability. A unique blend of polyester and polyurethane polymers.


Product Description

LastiSeal Brick & Concrete Sealer is a state-of-the-art, polyester-polymer, waterproofing sealer for concrete, bricks, pavers, porous stone and masonry, grout, and other porous building materials. LastiSeal penetrates deep into the substrate (up to 4″) to seal internally. It fills the pores, encapsulates particles, bonds the substrate, and cures as a hard plastic. It strengthens and waterproofs, reducing water penetration and protecting against deterioration. Unlike paints or surface sealers, LastiSeal does not leave a film on the surface, color, or gloss. It does not make it slippery. Water-based. Quick and safe spray-on application. Eco-friendly. Matte/flat finish. Seal and protect your exterior brick walls and veneer, brick chimney, paved patio and pool deck, driveway, fireplace, concrete blocks, splitface blocks, man-made stones, and other porous masonry.
