SC25 is AMAZING

I purchased my 1st 5 gallons to coat 2 new sidewalks that I had poured that are constantly in the path of my lawn irrigation. Five star reviews about this product were all deserved. Water simply beads-up likely preventing staining in the long run. I thought I had enough product left to seal my driveway, but only got about half finished, before needing to order another 5 gallons. However, the picture attached to this review clearly shows how well SC25 works - after a light rain, the completed half in the foreground clearly shows protection while the half in the background shows water penetration - a real enemy in freeze/thaw environments. Thanks for a great product.

Awesome and easy to use sealer!

This product is amazing! We had new concrete steps and pad poured and wanted to preserve them. I sprayed SC25 on both and then after several hours it rained..hard! The water simply beaded up!! I had called to ask about what sprayer to use and got the best, and kindest, response from the Customer Service gentleman who explained everything I needed to know to move forward confidently. A simple rinse out of the sprayer after using and done. I would absolutely recommend this product, and especially this company, a small family owned business that stands behind their products.
