However Flex Seal Liquid is. We have never tested it for this use. I'm not sure it will take away the odor since there will still be a hole in the cat box for the odor and cat to escape. **Q: I am trying to seal a water fountain. but i want it to be blue. can i use the flex seal liquid first and then spray the blue flex seal for color?** A: I did not use the flex seal liquid, but I did use the blue flex seal on an inside pond, and it has held up very well **Q: How many cans do I need to paint a canoe?** A: Not sure exactly but a can doesn't cover a large area depending on how thick you need to apply it. We used ours for smaller areas and it worked great! ## Customer Reviews ### ⭐⭐⭐⭐ Cumple parcialmente *by D***A on 7 June 2026* Lo usé para un tanque de 5mil litros y sello en gran parte la fisura pero me imagino por la cantidad de presión que genera esa cantidad de agua no logro sellar totalmente la fisura ### ⭐⭐⭐⭐⭐ Fabulous product *by S***Y on 12 May 2026* Fabulous product ! My ceramic outdoor barrel-style fountain developed a leak. I sprayed the Flex Seal on the inside and the problem was fixed immediately. No more leak and I can enjoy my fountain again. ### ⭐⭐⭐⭐⭐ LOVE THIS STUFF!! *by H***S on 26 June 2021* After having a leak in my pond tarp and reading a pond site that said I can use Flex Seal to cover up the punctures in the lining. I used Flex Seal tape to put over the holes and then put a clear coat of Flex Seal spray over that. Then I thought I would try the blue spray because I really don't like the look of the black tarp. So maybe I went a bit crazy covering the WHOLE tarp but I think it looks far better than the black and it has sealed the leaks. It sprayed nice and evenly. I made sure to shake the can really well and sprayed in a swift motion. No drips or uneven areas even was able to spray up to the edge of the wood boards without getting it on them but spraying between the tarp and board. Had to get a few more bottles just to finish up in the one corner where I ran out of spray. Can't wait to get the water and turtle in it. ## Frequently Bought Together - Flex Seal, 14 oz, Blue, Stop Leaks Instantly, Waterproof Rubber Spray On Sealant Coating, Perfect for Gutters, Wood, RV, Campers, Roof Repair, Skylights, Windows, and More - Flex Seal Spray Flood Protection, 10 oz, 1-Pack, Waterproof Rubberized Coating, Removable, Use on Door Tracks, Seams, Sills, Small Openings, Corners, and Irregular Shapes and 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.no/products/552777220-spray-rubber-sealant-coating-14-oz-blue](https://www.desertcart.no/products/552777220-spray-rubber-sealant-coating-14-oz-blue) --- *Product available on Desertcart Norway* *Store origin: NO* *Last updated: 2026-10-04*
