Product Description
LastiSeal Brick & Concrete Sealer (5 Gal) – Deep Seals and Strengthens Brick, Concrete, Pavers & Porous Stone – 15-Year Protection – Natural Flat Finish
- DEEP SEALS & STRENGTHENS FROM WITHIN – Deep-penetrating polyester/polyurethane formula cures within the pore structure of brick, concrete, block, mortar, and porous stone to help strengthen masonry from within. Helps reduce dusting and wear while extending the service life of treated surfaces.
- LONG-LASTING 15-YEAR PROTECTION – Designed to provide up to 15 years of protection on properly prepared porous masonry surfaces. Unlike topical sealers and surface coatings that can wear away over time, LastiSeal penetrates below the surface and becomes part of the substrate. Will not peel, chip, or flake.
- WATER-RESISTANT YET BREATHABLE – Helps reduce water absorption and moisture intrusion while allowing trapped moisture vapor to escape. Unlike film-forming coatings, LastiSeal penetrates below the surface to help protect masonry without sealing in moisture. Helps reduce conditions that contribute to efflorescence and concrete dusting.
- FOR BRICK, CONCRETE, BLOCK & POROUS STONE – Designed for brick, concrete, pavers, mortar, grout, stucco, concrete block, cinder block, CMU, split-face block, limestone, sandstone, cultured stone, & other absorbent masonry surfaces. Ideal for chimneys, retaining walls, driveways, patios, pool decks, walkways, and other exposed masonry structures.
- NATURAL FLAT FINISH – NO FILM, NO GLOSS – Preserves the natural appearance and texture of brick, concrete, pavers, block, and porous stone without creating a glossy coating or slippery surface. Because LastiSeal penetrates below the surface, it does not form a film that can peel or flake.
- IDEAL FOR AGING & WEATHERED MASONRY – Deep-penetrating formula helps preserve older brick, concrete, mortar, and porous stone by reducing water absorption and supporting long-term masonry protection. Popular for restoration, preservation, maintenance, and historic masonry projects.
- WATER-BASED & EASY TO APPLY – Apply with a low-pressure sprayer or paint roller to interior and exterior masonry surfaces. Low-odor, non-flammable formula is ideal for garages, patios, driveways, chimneys, retaining walls, and other residential or commercial applications.
- IDEAL FOR CHIMNEYS, RETAINING WALLS & MASONRY RESTORATION – Designed for chimneys, retaining walls, brick facades, masonry walls, stone structures, and other porous masonry exposed to weather and moisture. Popular for residential maintenance, historic masonry restoration, preservation projects, and long-term protection of aging masonry surfaces.
- RESIDENTIAL, COMMERCIAL & INDUSTRIAL USE – Suitable for homes, warehouses, workshops, commercial buildings, industrial facilities, maintenance shops, and other high-exposure masonry environments. Designed for long-term protection of concrete, brick, block, mortar, and porous stone surfaces.
LastiSeal is a unique, state-of-the-art, waterproofing sealer for bricks, concrete, mortar, stones, and porous building materials backed by a 15-Year Waterproofing Warranty. This waterborne, polyester-polymer and polyurethane sealer, penetrates up to 4 inches inside brick, mortar, grout, concrete and masonry. LastiSeal fills the pores internally, bonding the substrate and curing as a hard plastic inside. A sealed surfaces will shed water and unless too rough, bead for years to come! UNSURPASSED PROTECTION and SERVICE LIFE - Unlike paints or surface sealers, LastiSeal will not change the appearance or your brick, concrete, or masonry. LastiSeal does not form a surface film and will not leave a gloss finish or color on the surface. Once cured (24 hours), the seal is practically permanent! SAFE, INDOOR/OUTDOOR USE: Seal bricks walls and floors, indoor and outdoors, basement concrete, outdoor concrete, pavers, driveways, pool-decks, patios, stones, tiles, grout, koi-pond, porous stone and even wood!
