LastiSeal® Concrete Stain & Sealer Customer Testimonial - "We decided to stain the concrete to create a warmer and more inviting backyard. I researched concrete paints and stains for several months. I found the LastiSeal product during my research and told my husband this is the product for us. When I called to order, the sales person encouraged me to order a test sample to make sure..."

My driveway and sidewalk are 8 years old, we live in SW Florida, sprinklers, constant rains during our rainy season and the humidity and heat, makes for a great growing place for mold. The concrete was black with algea and mold, got slick when wet. I used a 2000 psi electric pw and Simplegreen HD to prepare for the sealer. I used 10 gals of RadonSeal Plus, the first i used a roller, second coat i used a garden sprayer. This product works great leaves the concrete looking natural.

"This was the best masonry seal I have ever used. I have been in the painting and remodeling for over forty years. Have used many products. Lastiseal applied exactly like instruction. We applied two coats in 8 hrs. Was amazed to watch it fill the cracks in brick and mortar lines. Look forward to using more." - Bill from Ennis, TX 1m
