It prevents water from from penetrating the concrete while allowing the concrete to breathe. Like any surface it is important to clean up sources of possible stains to prevent discoloration **Q: is this sold in local big box stores?** A: No. Only from the web. **Q: I applied this to my concrete patio last year. Can I apply it again this year without stripping the previous coat off (I will power wash first)?** A: I have in the past applied the year after the initial coat. It seemed to work well. I would not use a power washer, however, since that might strip the previous year's coat. ## Frequently Bought Together - MasonryDefender Concrete Sealer for Driveways, Patios, & Sidewalks - Deep Penetrating Water Repellent Protection - Silane Siloxane Sealer - 1 Gallon - Chapin 20000 Made in USA 1 -Gallon Lawn and Garden Pump Pressured Sprayer, for Spraying Plants, Garden Watering, Weeds and Pests, Polypropylene, Translucent White - MasonryDefender All-Purpose Masonry & Concrete Cleaner, 2 LB Pail - Cleans Driveways, Sidewalks, Patios, Garage Floors, Pavers & More --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/72166533-masonrydefender-concrete-sealer-deep-penetrating-water-repellent-silane-siloxane-1](https://www.desertcart.jp/products/72166533-masonrydefender-concrete-sealer-deep-penetrating-water-repellent-silane-siloxane-1) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-08*
