LastiSeal Brick & Concrete Sealer 2.5-gal – Flat Finish. Waterproofs & Strengthens Brick, Concrete, Pavers. Interior/Exterior.

Q: What's the cleaning procedure prior to using LastiSeal? I have pavers and usually just pressure wash a few days before

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

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.

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?

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.
