Protects against the growth of algae and molds. LastiSeal is not available in stores but is shipped by courier directly from factory. (There are no similar sealers available in stores.)
LastiSeal™ is a unique, state-of-the-art waterproofing sealer for concrete, bricks, stones, and porous building materials. This waterborne polyester polymer and polyurethane sealer penetrates 2–4 inches into concrete, fills the pores, bonds to the substrate, and cures as a hard plastic. It's like injecting epoxy into the capillaries in bricks, concrete, or masonry. (Polyester is called the "poor man's epoxy.”)
LastiSeal Brick & Masonry Sealer internally waterproofs the substrate. Unlike paints or surface sealers, it does not form a surface film. It cannot peel or crack or wear off – the seal is permanent. Backed by a limited 10-Year Waterproofing Warranty. The surface sheds water and unless too rough, beads.
At the same time, LastiSeal Sealer strengthens the substrate internally and hardens the surface. It gets noticably harder to hammer a nail into a brick sealed with LastiSeal.
LastiSeal seals and waterproofs a wide range of porous materials:
Clay bricks, brick veneer
Mexican tiles, pavers, adobe
Concrete blocks, cinder blocks, CMUs, splitface blocks (unless the pores are too large)
Poured concrete floors and walls, shotcrete, gunite
Internally colored concrete, acid-stained concrete
Mortar, stucco, plaster, grout
Porous natural or man-made stones, limestone.
"LastiSeal Brick & Masonry Sealer" disappears into the concrete, bricks or masonry, leaving no film or gloss on the surface. Unless over-applied, it does not make the surface shiny and does not make it slippery. It leaves a matte (dull) finish.
“LastiSeal Brick & Masonry Sealer – Satin ” is enriched with acrylics to leave an attractive low gloss, satin finish on smoother surfaces. But like acrylic sealers, it may reduce friction of the surface.

COVERAGE: Greatly depends on porosity. Typically 200-220 sq. ft./gallon on indoor poured concrete, or 150-200 sq. ft./gallon on outdoor concrete, or 120-150 sq. ft./gallon on porous bricks. Very porous materials may need a second lighter application next day.

Seals floors and walls, new or old, indoor or outdoor.
Not tested for use on surfaces continually submerged in water, like pools, ponds, and tanks.
Permanent – Paints or surface sealants you can buy in stores will soon crack, peel, or wear off because of UV-rays, water or vapor pressure, saponification (reaction with lime from the concrete), efflorescence (”white powder”), and traffic. Then, you have to remove the old paint (or it will start peeling even faster) and re-paint the surface.
Water-repellent sealers sold in stores have to be re-applied every year and in the long run, will cost you much more than LastiSeal.
Not dependent on cement content – Unlike RadonSeal concrete sealer, LastiSeal does not depend on a chemical reaction with the substrate. It just fills the pores and hardens. This allows it to seal internally colored concretes and fibercrete.
However, RadonSeal is the best sealer for standard-quality poured concrete or blocks because of its deeper and tighter seal and is also guaranteed to seal against radon gas. And RadonSeal is ideal for use inside ponds, pools, and reservoirs.
LastiSeal requires a dry and bare surface for application, while RadonSeal is applied on damp surface.
LastiSeal leaves the surface paintable except for latex paints or silicone. Since the pores are filled, stucco, thinset, mortar, or patching compounds do not adhere well.
