LastiSeal Brick & Masonry Sealer – Deep-Penetrating Sealer for Brick, Concrete, Stone & Masonry – Water-Resistant Protection for Interior & Exterior Surfaces – 15-Year Service Life (1 Gallon) - Hardware Sealers - desertcart.com

Review: Great Rain Barrier - This is a great product. Have used it for years. Great at sealing out rain and moisture. Easy to apply.
Review: Works great - This is good stuff, it sprays on very nice and covers well soaks in and drys fairly quick. No reason to put 2 coats on, the second coat just beads up and runs off. I Put it on old brickwork that I had to do tuck pointing on. It sealed the new mortar and old brick with no issues. I put it on with the temp just at the low end 50*and it still dried pretty fast under 30 min. The old brick really sucked up the sealer so I only covered about 30 sq ft in 1/2 gallon. It is a bit more expensive than other sealers but if it lasts as long as it advertises then it’s well worth the cost, I will buy more in the spring when I redo the rest of the brick on the house
