Ideal for roof repairs, basements, RVs, marine applications, and more, it dries fast to a glossy finish and protects against rust, corrosion, and moisture damage. ## Description Starts out as a thick liquid and dries to a super strong, flexible, watertight, rubberized coating. Blocks out air, water, and moisture for a superior seal, virtually anywhere. Extends the life of patio furniture, pool pumps, RV and shed roofs, and more. Expands, contracts, flexes and stretches. Resists rain, snow, sun, and hail. Works on all types of surfaces, even challenging ones, like metal and glass. Use indoors and outdoors for basement waterproofing, foundation fixes, roof repairs, and more. Fully clean and dry the surface for best results. Etch the surface to help with adhesion if needed. For the best application, use a standard disposable paint roller or paint brush. Apply several even, thin coats and wait 24 - 48 hours for each layer to fully dry before adding the next. Always place the lid back on the container after each use. If drying occurs, remove any skin before using product. ## Features - Flex Seal Liquid is liquid rubber in a can!

If they were my chairs I would use felt pads that you can find in any hardware store. **Q: Would a metal surface become insulated electrically after this was applied? Thinking of a tight car battery compartment...** A: Not enough to protect the battery from eventually shorting out. I would recommend securing a thick piece of rubber between the battery terminal and the metal close to it. **Q: How long dose this take to dry** A: It takes at least 24-48 hours for Flex Seal Liquid to dry based on the thickness of your application. **Q: My child has a basketball post with a plastic base that holds water. The base has a leak. Is this product suggested? If so, any prep suggested?** A: Anything works better with a little prep., sandpaper and clean. It should do well. Also as a add the new tape would probably work better. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Love this stuff!! *by on Reviewed in the United States October 21, 2025* Love this stuff! Was able to use it to help seal various different parts on my 69 Dodge Dart Project. Has a nice glossy texture and dries pretty quickly. Helps protect my components in my car and keeps them from cracking. It is a good texture for most any projects. I have used it on other applications too. It's nice that it's a versatile project that I can use for almost anything! ### ⭐⭐⭐⭐⭐ Works great for my purposes. That is to keep things from sliding around. *by on Reviewed in the United States April 5, 2018* Two or three years back, I 3D printed some drink coasters to use. But one problem was that they would slide easily.So I ordered Flex Seal in this week to try coating the bottom of them creating a non-skid surface.It takes 48 hours for this stuff to cure completely. But after 24 hours with my 1st test, it appears that I am getting what I wanted. A non-skid surface on the bottom of these coasters.The stuff states that it can be used as a sealant. But there are many products that can be used as a sealant, and this 48 hour cure time is a drawback. 24 hours before it is safe to handled.It also states that it can be used as liquid electrical tape. Again, I agree with this. But that curing time is a drawback.But for coating surfaces, it is a winner in my book. (So far....)Update: April 9, 2018The stuff worked great on the PLA plastic coasters. PLA plastic is a material made from corn.However, I had 3D printed 1 coaster with ABS plastic with a rough base. ABS plastic is the stuff used in cars. Here the Flex Seal appeared to cure in 24 hours. However, that coaster required 2 coats of Flex seal because it had soaked into the plastic..Having used my coasters with the Flex seal bases for a few days now, they work exactly as planed. Put a cup in them with any liquid, and they are planted and un-moving. They won't slide off of a table without a lot of help.I suspect that this application would work for many materials where you don't want them sliding around.(Hmmmm...... I wonder if I can make some non-skid pads under my old laptop? Maybe the same thing for my sound speakers on my desktop or TV? It's an idea...) ### ⭐⭐⭐⭐ A little expensive, but it does the job. *by on Reviewed in the United States April 6, 2026* I used this on a steel trash can that I store bird seed in. The top had a gash in it and no matter what I did, water would get in and ruin the seed. I hated to throw it away since that was the only problem. A can of this, and the problem was solved. It's a little spendy for the amount you get which is why I removed 1 star. But there's no question it works good. My only other gripe is that it takes a long time to set up and dry. So if you can keep your project level and dry for 24 hours, that will go a long way to helping it cure. I just used a disposable paint brush to apply it and I kept the now hard brush for future applications. It's fairly durable depending on what you're trying to accomplish. I tried using it on the feet of my deck chairs hoping it would save wear and tear on my deck? Not a good idea, it just fell off after a couple of uses. But for sealing, this is a good product. ## Frequently Bought Together - Flex Seal Liquid, 16 oz, Black, Liquid Rubber Coating Sealant, Waterproof, Flexible, Breathable, and UV Resistant, Roof Repair, Basements, RV, Campers, Trailers, Marine, EPDM, Masonry - Flex Seal 2-Pack Black 17oz Stop Leaks Instantly, Waterproof Sealant Coating For Gutters, RV, Roof, Skylights, Windows --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/24980581-flex-seal-liquid-rubber-coating-sealant-waterproof-flexible-breathable-uv](https://www.desertcart.sn/products/24980581-flex-seal-liquid-rubber-coating-sealant-waterproof-flexible-breathable-uv) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-05-31*
