LastiSeal Brick & Concrete Sealer Satin (5-gal) - Water-Based Penetrating Sealer for Brick, Concrete, Stone, & Porous Masonry - 15-Year.

Long-lasting Protection: This deep-penetrating concrete and brick sealer offers up to 15 years of protection while helping to reduce water absorption, weathering, and surface wear. It leaves a subtle satin (low-gloss) finish without creating a heavy coating. Satin Finish: Delivers a subtle, low-gloss finish that enriches the natural texture and color of brick, concrete, and pavers. All-Weather Protection: Aids in protecting concrete, brick, pavers, mortar, and porous stone from rain, snow, road salts, and freeze-thaw cycles. Surfaces dry quickly, helping to reduce cracking, spalling, and long-term weather damage. Reduces Efflorescence: Helps minimize water absorption to lessen efflorescence, protecting masonry surfaces from staining, residue buildup, and surface deterioration. Advanced Water-Based Formula: A special blend of polyester, polyurethane, and acrylic polymers forms a durable, breathable masonry sealer that works below the surface to strengthen and protect without trapping moisture. Hardens & Strengthens: Helps reduce surface dusting and harden soft mortar joints while reinforcing porous concrete, brick (including historic Chicago brick), sandstone, and mortar, enhancing durability and reducing surface wear. Versatile Indoor & Outdoor Use: Appropriate for use on chimneys, driveways, pool decks, patios, garage floors, retaining walls, and fireplaces. Ideal for a broad range of interior and exterior porous masonry surfaces
