LastiSeal Penetrating Brick and Masonry Sealer

Long-Lasting Protection for Porous Brick, Concrete, and Masonry

LastiSeal Brick & Masonry Sealer

LastiSealĀ® 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 micropores and curing as a hard plastic! (Similar to plugging the pores with epoxy.) LastiSeal waterproofs, preserves, and protects porous concrete, brick, and masonry against:

  • WIND-DRIVEN RAINS – Seals against wind-driven ("sideways rain") water intrusion.
  • NEGATIVE SIDE WATER PRESSURE – Prevents water seepage through masonry underground.
  • FREEZE-THAW – Protects surfaces against freeze-thaw and road salt damage.
  • CRUMBLING – Hardens concrete and brick to protect against pitting, spalling, dusting and crumbling.
  • SPILLS – Resists spills, motor oil, grease, and chemical spills. Makes surfaces easier to clean.
  • MOLD, ALGAE - Reduces the growth of mold, mildew and algae. Makes for easier cleaning.
  • HUMIDITY – Reduces water vapor transmission through the substrate.
  • EFFLORESCENCE – Reduces unsightly efflorescence.

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 Wateproofing and Service Life Warranty.

What Makes LastiSeal So Special?

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 many 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!

  • WATERPROOFS & STRENGTHENS
  • ECO-FRIENDLY. NON-TOXIC
  • SLIP-RESISTANT. SAFE FOR VEHICULAR TRAFFIC
  • DOES NOT ALTER SURFACE APPEARANCE
  • EASY SPRAY-ON APPLICATION. DRIES QUICK
  • SHEDS SURFACE WATER & CHEMICAL SPILLS
  • USE ON A VARIETY OF POROUS MATERIALS
  • REDUCES CLEANING TIME. .

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 making maintenance less routine and much easier (especially for driveways, and brick and concrete pavers).

LastiSeal - SatinChoose LastiSeal FLAT or SATIN

LastiSeal FLAT (most popular) does not change the appearance or profile (friction) of the surface. Making it a safe choice for sealing horizontal surfaces like stairways, pool decks, patio pavers, high-vehicular traffic areas, commercial flooring, sidewalks, driveways, parking lots, 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 colored or stained concrete.

Coverage

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.

  • BRICKS – 150-225 sq. ft. (per gal)
  • OUTDOOR POURED CONCRETE – 150-200 sq. ft. (per gal)
  • INDOOR POURED CONCRETE – 200-250 sq. ft. (per gal)
  • HEAVYWEIGHT CONCRETE BLOCKS – 100-150 sq. ft. (per gal)
  • CINDER BLOCKS – 75-125 sq. ft. (per gal)
  • GROUT – 16 sq. ft. (per 8-oz.)

What Are People Saying

The Best All-Purpose Sealer for Porous Building Materials

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, UV Resistant, and Vapor Permeable

ECO-FRIENDLY - LastiSeal Brick & Masonry Sealer is a 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 solutions 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.

Application Instructions

CONDITIONS – The brick, concrete, and masonry needs to be thoroughly dry. Let 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 4 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.

How to Safely Remove Efflorescence

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 to 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.

Comparison with Other Brick Sealers

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.
