A friend of mine said he'd never even seen roof tiles like were on my shed. Over the years I've lost a couple of tiles, the tiles were getting very worn and you could close the doors and see light coming through the roof. Needless to say, rain water was not my shed's friend. Thought about replacing the roof but the cost was way out of reason for a shed. Found this product and after reading the many reviews I though I'd give it a try. I replaced 2 roofing tiles and started coating the roof. I put 3 coats on the rood, a little less than 3 gallons. This stuff is amazing. I would have never believed it, but my roof is completely sealed. I can't even lift or separate the tiles now. There is no light penetration and we've just had 4 days of constant rain and there is no leaking. It does go on brown in color but soon changes to black. The first coat took a little longer but after that the second and third coats just went right on. I managed to get a lot on my hands but it washed off with soap and water. I had about 1/3 gallon left and since there is no way you can reseal the container I decided to coat the wood on my trailer. Can't say if that was a good idea or not but figured it couldn't hurt. For less than $200 I got a completely sealed roof that I expect will last many years. If not, I'll just get another gallon in a few years and re-coat it. I highly recommend this product. Read all the reviews to insure it will serve your purpose, but I am very thankful I found it. Review: Waterproof sealant - This is the perfect product if you’re wanting to seal wood so it’s protected from dampness and moisture. Goes on easily but very sticky to gloves. You can use cheap brushes as you’ll have to throw them away each time.

We are sealing our new concrete pond with this product = will not have fish in** A: New concrete needs to cure as per the installation instructions. Applying any of the Liquid Rubber products or most waterproofing products prior to a full cure may compromise the curing process of the concrete. **Q: I have a black plastic pond i got from home depot. will it adhere to that material?** A: Yes, put a few coats on. Let each coat dry well (24)hrs . You can spray on inside of pond. I used a undercoating product used for undercoating cars for the outside of pond. I put 3 coats on. I let each coat dry for 2 days before applying the next coat. All worked great my pond is like new and no leaks and all of my goldfish are fat and happy! Good luck! Take your time and cover every spot even sides. Make sure the pond is very clean before u start applications. I used a ruff kitchen pot scrubber to scrub clean. **Q: Does this project leave much of an odor after it has set?** A: Haven't smelled any odor. When putting it on there is a usual rubber smell like a basketball, but it doesn't seem to last very long. And it smells just like putting rubber on, which wasn't bad. It works for me. **Q: what color is it when it dries?** A: The product is brown when it is wet and black when it dries. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Amazing Stuff *by W***R on June 2, 2021* I have an older 12 x 18 foot gambrel roof storage shed used for lawn mowers, tools, etc. There is no telling how old the shed is since it was here when we bought our place 15 years ago.

Goes on easily but very sticky to gloves. You can use cheap brushes as you’ll have to throw them away each time. The product is very thick and tar like. ### ⭐⭐⭐⭐ Looks brown when it is wet but dries black *by A***E on November 7, 2025* Goes on and looks brown but dries black. Easy to apply - like a thick paint. Seems like it will work great - dried well. Will give a better update on how well it works after it has been on for a period of time. Only had it on for 1 day. ## Frequently Bought Together - Liquid Rubber Waterproof Sealant – DIY Leak Repair Coating for Flat, Metal & Low Slope Roofs, Foundations, Gutters & More – Flexible Protective Membrane - Black - 1 Gallon - Liquid Rubber Geo-Textile - Fix Leaks - Repair and Restore - Easy to Use, 4 Inch x 160 Foot Roll - Liquid Rubber Caulk - Hybrid Adhesive and Protective Sealant, White, 4 Pack --- ## 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.za/products/14871374-waterproof-sealant-roof-and-gutter-coating-black-1-gallon](https://www.desertcart.co.za/products/14871374-waterproof-sealant-roof-and-gutter-coating-black-1-gallon) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-09-06*
