Will it seal this?** A: Hello, thank you for reaching out! Many people have had success using https://www.amazon.com/dp/B00OX6OU5S to seal their grout. **Q: I have a leak on my shower drain, would this work to seal the leak on PVC pipe?** A: Yes many people have had great success sealing their pipes with Flex Seal. **Q: Will flex seal work on concrete? I have a leak in my koi pond, would flex seal hold the leak while being underwater?** A: Yes many people have had great success using Flex Seal on concrete. We recommend using Flex Seal Liquid on your koi pond though since it is plant and animal safe. Flex Seal in the aerosol can is not animal safe. **Q: I have a couple of cracks in a plastic pond shell. Around 100 gallon pond. Would this seal them?** A: the tape might do the job--I sprayed on to a faux leather chair -- it's peeling off--I might get more tape seal.. ## Customer Reviews ### ⭐ Not good *by H***Y on 6 January 2023* Not good ### ⭐ Ca *by W***8 on 7 February 2023* Not worth it ### ⭐ Poor prodect *by A***F on 18 June 2021* Not useable ## Frequently Bought Together - Flex Seal, 14 oz, Black, Stop Leaks Instantly, Waterproof Rubber Spray On Sealant Coating, Perfect for Gutters, Wood, RV, Campers, Roof Repair, Skylights, Windows, and More - Flex Tape, Original Thick Flexible Rubberized Waterproof Tape - Seal and Patch Leaks, Works Underwater, Indoor Outdoor - Home RV Roof Plumbing and Pool Repairs, Black, 4 in x 5 ft, Pack of 1 --- ## 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.pe/products/256348929-flex-seal-14-oz-black-stop-leaks-instantly-waterproof-rubber](https://www.desertcart.pe/products/256348929-flex-seal-14-oz-black-stop-leaks-instantly-waterproof-rubber) --- *Product available on Desertcart Peru* *Store origin: PE* *Last updated: 2026-10-07*
