We power washed the deck before applying the cleaner, and it dried looking practically brand new. **Q: Is this product water based?** A: I haven't put it down yet. I'm not sure if it's water based or not. I'm ordering a second gallon before I start as I won't have enough to finish. I will post what I find once I've had an opportunity to use it. **Q: Will this work on all composite decking** A: I only know that it worked on my 14-year old Trex decking. ## Frequently Bought Together - Defy Composite Deck Waterproofing Sealer 1 Gallon - DEFY Composite Deck Cleaner, 2 LB Container - Superio Deck Scrub Brush with Long Handle 48 Inches, Heavy Duty Stiff Bristles Grout Scrubber with Scraper - Cleans Hot Tub, Swimming Pool, Granite Tiles, Bathroom, Patio, Kitchen, Wall and Deck --- ## 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.co.th/products/728234516-defy-crystal-clear-composite-deck-waterproof-sealer-1-gallon](https://www.desertcart.co.th/products/728234516-defy-crystal-clear-composite-deck-waterproof-sealer-1-gallon) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-24*
