FREE SHIPPING on 5-gallon quantities of LastiSeal Brick & Masonry Sealer!
LastiSeal® Masonry & Brick Sealer is a water-based, polyester polymer and polyurethane sealer for concrete, brick, stone, and other porous masonry.
Quickly and easily applied, LastiSeal® penetrates deep below the surface (2-4 inches) and fills pores, encapsulates particles, bonds the substrate, and cures as a hard plastic. LastiSeal® seals internally to permanently waterproof the substrate and greatly reduce water vapor transmission.
Unlike paints or surface sealers, it does not leave a film, color or gloss. Matte/flat finish.
Seal your brick walls, brick chimney and fireplace, colored concrete,
man-made stones, concrete, blocks, and other porous masonry.
LastiSeal penetrates deep into masonry and hardens. Unlike paints or
surface sealers, it does not leave a film, color or gloss.
Approximate coverage 150-220 sq. ft./gallon on concrete or
120-150 sq. ft./gallon on porous bricks.
Very porous materials may need a second lighter application.
Shipped in TWO (2) 2.5-gallon containers.
