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.
  • Ideal for interior and exterior brick, concrete, stone, pavers, mortar and other porous masonry
  • Protects against water seepage, freeze-thaw damage, staining, algae and mold, wind-driven rain, cracking and spalling
  • Will not change the look or feel of your masonry, treated surfaces are not slippery
  • Safe for indoor or outdoor use, easy to apply, no odor, non-hazardous, non-flammable
  • Quick and easy application using a hand-pump sprayer or roller
  • Seals up to 250 sq. ft. per gallon, actual coverage will vary with surface porosity
  • Treated surfaces can be painted (no latex)

Questions & Answers

Can the product be applied while the brick and mortar are damp? Or, does it need to be applied after the areas are completely dry? I have 3 chimneys on my 100 year old home, and they all wick moisture from rain water, dampening the ceiling areas inside the house.... I'm beginning to think the rain won't stop until summer, and I need a product that can seal a damp surface. Thanks!
Asked by: Steve
Allowing your brick and mortar to fully dry and cure is a critical step in their installation. Therefore I would wait at least 24 hours after they appear fully dried. Hope that helps.

We have cracks in our garage roof that allow water to seep into the garage. Will this product seal the cracks and prevent the water from seeping through?
Asked by: htmiser
LastiSeal is a low-viscosity sealer that penetrates and seals the matrix of porous brick, concrete, and masonry against capillary water seepage. LastiSeal can aid in sealing small fissures, but is not guaranteed to seal cracks, gaps, seams, corners, joints, saw cuts, and holes where water can easily leak through.

I just used silka self levelling concrete. My floor sweats in the summer. Is this the right product to use.

If so. How long do I need to wait before I can apply it?
Asked by: Ben
I don’t think it will. Moisture likely coming from humidity in the air condensing on a cold concrete floor. Get a de humidifier

We enclosed a covered 21'x14' open patio with a 2ft high brick\mortar wall and 6' tall weather proof vinyl windows, creating a wonderful Sun Room addition. Our concern for weather penetration through the double brick wall and mortar was confirmed with the first heavy rain storm. Although there was no standing water intrusion, the very porous clay bricks\mortar quickly acted like a dry sponge and dampened the now living space interior of the sun room's masonry window foundation...not good. After doing extensive on-line research, I came upon the RadonSeal products and quickly identified their polyester polymer based "LastiSeal" Brick and Masonry Sealer as what we needed to block any moisture\rain intrusions. After speaking with Craig at RadonSeal, he confirmed that their LastiSeal product would be a great solution to our sun room's moisture issues. We only had 50sf to seal (exterior brick), just purchased a 1-gallon container directly from RadonSeal. As weather became optimum (but winds were strong), I choose to apply the treatments with a brush (very easy and simple). Our bricks and mortar are so porous, the first treatment soaked in with the surface dry-to-the-touch in 5 minutes! As per directions, 24 hours later I reapplied (again with brush) and the second application took 2 hours for surface to dry. Through all of the applications and once dry to the touch, the brick\mortar surfaces returned to their original colors, again matching our home's brick-veneer facade! Two days after the 2nd application and again twice in the past 3 weeks, thunderstorms soaked the brick\mortar exterior walls of the sun room with absolutely NO moisture intrusion into the interior...WOW! We really love our new sun room addition and understanding that LastiSeal never needs reapplying, I can unequivocally state, "LastiSeal is Worth Every Penny"!!!

I chose this product since it was the only one that stated clearly that it would not change the feel or appearance of the pavers - and it did not. Application was easy with a sprayer, but the stated coverage seemed to be more then the actual coverage so I had to order a second bottle and then go thru the cars out of garage and no walking on drive a second time. Part of the issue may have been either too much pressure applying too much product and/or holding the sprayer to close to surface and reducing the size of the spray area - but I still think the listed coverage is a bit over estimated. As for the product itself, only time will tell. I bought based on other reviews and the stated life of the product.
