Penetrating concrete sealers | Do-it-yourself basement waterproofing | Basement and concrete repairs
LastiSeal® Brick & Masonry Sealer is a unique, state-of-the-art, penetrating waterproofing sealant for porous bricks, concrete, blocks, pavers, stones, and other porous building materials. LastiSeal absorbs deep into the substrate (up to 4"), internally filling the micro-pores and curing as a hard plastic! (Similar to plugging the pores with epoxy.) LastiSeal waterproofs, preserves, and protects porous concrete, brick, and masonry against:
LastiSeal sheds surface water, is chemically resistant, and provides freeze-thaw resistance when applied to outdoor surfaces. It also helps block negative side water pressure when used for indoor, subterranean applications. Once cured, water cannot push the sealer out! LastiSeal is backed by a 15-Year Waterproofing and Service Life Warranty.
LastiSeal® Brick & Masonry Sealer is unique. There are no similar products in stores!
This waterborne, polyester-based sealer not only waterproofs but also bonds the substrate (polyester is sometimes called "the poor man's epoxy"). If your brick or concrete surface is dusting, flaking, or crumbling, LastiSeal will strengthen it! Preserving the condition and increasing the lifespan of the material for years to come. Once cured, surfaces become noticeably harder.
You will find that attempting to hammer a nail into the substrate will prove to be difficult!
EASY MAINTENANCE – LastiSeal will help block the build-up of dirt, grime, grease, oil, and chemical spills but also reduce the growth of mold, mildew, and algae. Thereby, making cleaning less routine and much easier (especially for driveways, and brick and concrete pavers).

Choose LastiSeal - Flat or LastiSeal - SatinLastiSeal - Flat (matte finish) does not change the appearance or friction profile of the surface. A safe choice for sealing horizontal surfaces like stairways, pool decks, patio pavers, high-vehicular traffic areas, commercial flooring, sidewalks, driveways, parking lots, concrete curbing, and much more.
LastiSeal - Satin is enriched with acrylic-polymers which enhances the appearance of the surface, leaving an attractive low-gloss finish. Satin is particularly suitable for indoor brick and masonry walls, washed-out patio pavers or building facades, brick walkways, and unsealed colored or stained concrete.

Coverage depends on the porosity and composition of the substrate. Older brick (like Chicago, Adobe, or Victorian brick) or overly porous concrete, and masonry may require more than one application for a proper waterproofing seal.
Customer Testimonials |

"I do know you do need to seal your slab. Don't go with a product from Lowe's - LastiSeal Masonry & Brick Sealer by RadonSeal is the best concrete and masonry sealer there is PEROID - it penetrates very deep and closes up all the concrete's capillaries. My parents had a concrete problem and I did tons of research as to the sealer that would work the best and I found LastiSeal and can't say enough positive things about it" "Hi, I just wanted to let you know how much I like your product, Lastiseal Masonry & Brick Sealer. I use it for the final sealer on my concrete sculptures. The best product I have found." – Randall Z., OH "I thought I would let you know that I covered half my house with the LastiSeal Satin sealer. It took about 7 gallons to do so. It was TOO windy to finish it Sunday. It actually changed my original red and black brick BACK to its original color. I did not realize it had turned to "orange and black". My wife had been calling it the "Emperor's New Clothes" as she did NOT think it was worth the cost. She said that she is now impressed..." – Weldon, Abilene TX See more LastiSeal Testimonials |
While LastiSeal is most commonly used for sealing brick and concrete, it can also be used for sealing porous pavers, stones, tiles, grout, and porous masonry. The rule of thumb is, as long as the substrate is porous you can use LastiSeal. You can even use it for sealing fibrous wood!
ECO-FRIENDLY – LastiSeal Brick & Masonry Sealer is an environment-friendly, non-toxic, nonflammable, and non-hazardous. Ultra low VOCs with no noxious odors. Not harmful to plants, grass, or aquatic life. Safe for use indoors and outdoors.
LONG-LASTING – LastiSeal has an unsurpassed service life of 15-years. Unlike paints or surface sealers, LastiSeal does not form a surface film (membrane coating). It seals the substrate internally and is practically permanent! Concrete sealers and brick sealers sold in stores have to be reapplied every couple of years. In the long run, LastiSeal is an economical solution even before considering all the labor.
UV RESISTANCE – Paints, coatings, and surface sealants are susceptible to delamination, flaking, peeling, cracking, or simply wearing away due to heavy traffic, UV-rays, water or vapor pressure, and efflorescence. Eventually, you would need to remove the old coating (or it will start peeling even faster) and recoat the entire surface. Since LastiSeal works by penetrating and sealing deep inside the material, it is not affected by ultraviolet rays or foot and vehicular traffic.
VAPOR PERMEABLE – LastiSeal waterproofs brick, concrete, and masonry, but still allows the substrate to "breathe" and dry out. It does not trap moisture and is commercially specced as such, a vapor-permeable sealant.
CONDITIONS – The brick, concrete, and masonry needs to be thoroughly dry. Allow the substrate dry for 2-3 days after a heavy rain. Let dry 3-4 days after pressure washing. Avoid heavy rains for 24 hours after the application. The surface and ambient air must be above 45 °F, but not hot in direct sunlight to avoid flashing. In case of LastiSeal SATIN, the surface temperature must remain above 45 °F for at least 24 hours.
SURFACE PREPARATION – Remove old paint, adhesives, oil stains, grease, and efflorescence. Vacuum excessive dust or dirt. Let new concrete cure for at least four weeks. Mask glass, metals, and plants and finished surfaces against over-spray. NOTE – Acid cleaners must be neutralized and thoroughly flushed with water before using the sealer. Test spot to ensure sealer is not reacting with any potential acid residue.

APPLICATION - TEST SPOT first on various areas of the surface to ensure sealer is penetrating. Apply LastiSeal® Brick Sealer using a hand-pump garden sprayer or a paint roller (3/4" nap). Spray a continuous saturating film on the surface (back-roll any puddles). If needed, a second coat can be applied 24 hours or later. Ready for foot traffic in several hours and for vehicles in 1–3 days, depending on the substrate.
USE AS A PRIMER FOR PAINT – LastiSeal is a great primer for paints, coatings, and flooring adhesives with the exception of latex, silicones, and siloxanes. Since the pores are filled, stucco, thinset, mortar, or patching compounds do not adhere well. It does much more than the common primers by waterproofing the substrate and reducing water vapor transmission, LastiSeal greatly extends the life of paints and clear coatings.
Water-repellent siloxane sealers or the common acrylic-based sealers sold in stores have to be reapplied every other year. In the long run, they would cost you much more than LastiSeal.
Not Dependent On Cement Content – Unlike RadonSeal® Concrete Sealer (our #1 sealer for concrete), LastiSeal does not depend on a chemical reaction with the substrate. It just fills the pores and hardens. This allows it to seal concretes and porous materials that RadonSeal cannot. However, RadonSeal is the best sealer for standard-quality poured concrete or blocks because it seals deeper and tighter and is guaranteed to seal even against radon gas. And RadonSeal is ideal for underwater use inside ponds, pools, and reservoirs.
