LastiSeal 2.5 Gal. Long-Lasting Waterproofing Brick Concrete and Paver Sealer

LastiSeal is a water-based, polyester-polymer and polyurethane sealer for brick, concrete, pavers, stones, mortar and other porous masonry. LastiSeal penetrates up to 4 in. and fills the pores, bonds the substrate and cures as a hard plastic below the surface. Unlike paints or surface sealers, LastiSeal will not change the appearance or feel of 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. Seal brick walls and floors, indoors and outdoors, brick chimneys, pavers, driveways, pool-decks, patios, stones, tiles, grout, water-features and porous stone. Non-toxic, non-flammable and non-hazardous. No odor. Ultra-low VOCs. Not harmful to plants. Protects against: Freeze-thaw damage, wind-driven rain, negative side water pressure, spalling, spills, mold, algae, humidity and efflorescence. Approx. coverage per 2.5 Gal. pail: Bricks - 400 sq. ft. to 500 sq. ft., Poured Concrete - 500 to 600 sq. ft. More porous surfaces may require a light second application.
