Penetrating Waterproofing Sealer for Long-Lasting Protection Protect and preserve your masonry with LastiSeal Penetrating Brick & Concrete Sealer, a high-performance, commercially used, polyester-polymer penetrating sealer designed to waterproof and strengthen brick, concrete, pavers, porous stone, limestone, concrete blocks, grout, and other masonry surfaces. Unlike clear surface coatings, LastiSeal penetrates deep, up to 4 inches, curing inside the substrate to form a hard, waterproof barrier that bonds, strengthens, and seals from within. 15-Year Waterproofing Warranty Enjoy Unsurpassed Durability.
