With a flat finish and up to 15 years of protection, it forms a durable barrier against water damage and staining, making it ideal for both residential and commercial applications. Easy to apply and safe for the environment, LastiSeal is your go-to choice for long-lasting masonry protection. ## Description Product description LastiSeal Penetrating Brick & Concrete Sealer Protect What Matters with LastiSeal Since 1997, LastiSeal has helped homeowners, contractors, architects, and property managers protect and preserve masonry surfaces, both indoors and out. Unlike traditional sealants that merely coat the surface, LastiSeal penetrates deep into the substrate to strengthen, seal, and safeguard concrete, brick, pavers, and other porous materials with invisible, long-lasting protection. Trusted by thousands, LastiSeal is the first line of defense against water intrusion, freeze-thaw cycles, road salts, cracking, pitting, and efflorescence. LastiSeal Penetrating Brick & Concrete Sealer is easy to apply, and suitable for both interior and exterior use. It contains no added solvents and has an ultra-low VOC content, well below California’s strict VOC limits. What Makes LastiSeal So Special? Common, over-marketed, siloxane/silane sealers, often promoted for their ability to bead surface water, typically have shorter lifespans. They do not absorb deeply into the substrate, nor do they strengthen the substrate. Traditional acrylic-based sealants , often marketed for their water-beading properties, typically have shorter lifespans. Being topical, they do not absorb or strengthen the underlying concrete. LastiSeal Brick & Concrete Sealer is a proprietary, polyester-based, penetrating sealer. It’s like pouring liquid plastic into the pores of concrete, brick, pavers, and other porous materials. Hardening the surface and delivering superior wear resistance against shoveling, weathering cycles, freeze-thaw, chlorides, deicing chemicals, and road salts. LastiSeal Penetrating Brick & Concrete Sealer – Flat and Satin Finishes Advanced Formulations for Natural or Enhanced Surface Appearance LastiSeal Penetrating Brick & Concrete Sealer is offered in two formulations: Flat and Satin. The Flat formulation maintains the substrate’s original appearance with no visual enhancement, ideal for applications requiring an untreated aesthetic. The Satin formulation incorporates acrylic polymers to impart a gentle, low-luster finish, subtly enriching the surface tone while maintaining breathability and substrate integrity. Long-Lasting Protection You Can Count On LastiSeal Delivers Up to 15 Years of Sealing Protection for Brick, Concrete, Pavers, and Masonry With a service life of up to 15 years, LastiSeal offers long-lasting protection without the need for frequent reapplication, unlike many other chemical sealers. This not only saves you time and money but also provides peace of mind, knowing your brick, concrete, pavers, and other masonry surfaces are protected for the long haul. Available in Three Convenient Sizes for Any Project 1-Gallon Jugs Ideal for smaller projects or touch-ups, LastiSeal is available in easy-to-handle 1-gallon jugs. 2.5-Gallon Containers Our 2.5-gallon containers offer a great balance of coverage and convenience for medium-sized jobs. 5-Gallon Twin Packs For larger applications, choose the 5-gallon twin pack, two 2.5-gallon containers bundled together for maximum efficiency and easy storage.

I have pavers and usually just pressure wash a few days before** A: If the pavers are generally clean and in good shape, then pressure washing is not always necessary. As noted on the instructions: SURFACE CONDITIONS Substrate should be dry prior to sealer application. Brick, concrete and porous masonry may require SEVERAL days to dry after heavy rain or pressure washing. Avoid rain for 24 hours after sealer application. Ambient air and surface temperatures must be above 45º and below 100º F during the application and for 24 hours after. Avoid applying to hot surfaces in direct sunlight, or in strong winds and excessive humidity. New concrete should be allowed to cure for at least 28 days. SURFACE PREP Surfaces must be clean, bare and porous. Remove paints, sealers, curing compounds, adhesives, oil, grease, mold, efflorescence and other contaminants that might interfere with the penetration of the sealer. Hard-troweled concrete surfaces require chemical etching or mechanical abrasion to increase porosity. A sufficiently porous surface should readily absorb the sealer. Use PowerEtch Concrete Etcher & Cleaner to obtain a proper surface profile. If chemical cleaners or concrete etchers are used, be sure to throughly rinse and remove them prior to sealer application. Mask surfaces not intended to be sealed. Vacuum or blow off excessive dust and loose particles. Cheers, ---------- Craig - Product Tech RadonSeal **Q: Will it work for a brick patio that we are enclosing for an Arizona room or porch** A: LastiSeal will seal any porous masonry. Bricks, blocks, sandstone, limestone....if its porous, LastiSeal is an excellent choice. **Q: Can this product be used in cold climates? I read that sealers on brick in cold climates can trap the water and cause the brick to flake.** A: I am using it in Wilmington, NC so can not give any feedback of using it in cold weather. It is doing exactly what I wanted it to do though **Q: Does concrete sealer work on rock walkways?** A: LastiSeal Brick & Concrete Sealer is a nano-chemical, PENETRATING sealer. It can be applied to POROUS surfaces/materials; poured concrete, concrete blocks, brick, mortar, pavers, limestone, sandstone, etc. It is not advised to use this product over rock surfaces. Rock is dense and simply will not absorb the product internally. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by D***7 on October 15, 2024* ### ⭐⭐⭐⭐⭐ Review *by M***. on October 16, 2025* ### ⭐⭐⭐⭐⭐ Review *by T***O on January 6, 2017* ## Frequently Bought Together - LastiSeal Brick & Concrete Sealer 2.5-gal – Flat Finish.
