Seal-Once Stay Clean Ready-to-Use Clear Coating Protects Surfaces from Mold, Dirt & Grime, 5 gal.

Time will tell how well this works but the application process was extremely easy. I used it on my new stepping stones in my landscaping to help prevent mildew and help preserve them for as long as possible. It didn’t change the look of the stones much at all, but I’m hoping it will help keep them nice and new looking for a long time. First pic is before, second pic is after.

I liked the Stay Clean Ready To Use Formula because there was no need to measure or dilute anything myself. I simply took a brush and applied the ready-made product to the boards. The product is odorless and has a slight blue tint, making it easy to see where it has already been applied - which really helps during the process. I treated all the wooden boards in the bathroom during a renovation to protect them from moisture damage; the product dried quickly, allowing us to continue working. I also treated the outdoor steps and they look great. It has been two months and there has been plenty of rain, yet the wood remains well-protected.

Easy to use. No mixing necessary. Clear instructions. Too recent to have full results to share but early indicators are positive.

I cleaned and used this on a small section of my paver patio that stays in the shade. It was easy to apply and has so far kept it free of green moss growth. I left the surrounding areas green to show the effectiveness.
