It's white. **Q: Rain barrel leaking thru small cracks in plastic ring/surface surrounding where faucet screws in. will this fix leak? or loctite epoxy better? thanks!** A: Used this on a koi pond skimmer extension I made from lexan which has remained leak free for 3 years with water running over it from a pool pump . So two different forms of plastic glued without leaks. This is some sticky sealant so I would say it would do the job. Sand the cracks just to roughup the surface with some 360 grit sandpaper and this sealant should fix your problem , it's flexable after it cures so movement won't break the seal . I also used this to glue a John deere riding mower seat back on the seat frame and it is still holding. Locite makes quality thread lockers and sealants and I have never had a bad day with their products. **Q: Will it work to hold a corner bumper to a metal dock?** A: Not by itself. You will need some fastener as well. This stuff does not bond well to some plastics such as HDPE or polypropylene. **Q: Will this work with EPS/XPS Foamboard? looking to seal DIY camper shell to trailer bed. Shell is 2" Pink foamboard sandwich covered with 1/8" plywood.** A: aIt will work but there are better alternatives out there it is more of a sealant it has good adhesion but takes 24 hours to reach full strength ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good good stuff *by R***G on 7 August 2026* Very good works well, but costly, ### ⭐⭐⭐⭐⭐ worked well. *by G***N on 21 October 2025* worked well. ### ⭐⭐⭐⭐⭐ This is awesome stuff! Recommended! *by R***. on 18 February 2025* I had a difficult problem. I bought a rainspout adapter which diverts water outside of the aluminum downspout into a water barrel. Problem was that it is made of rubber, flat, and up against an aluminum and wavey shaped downspout. Of course it leaked like crazy. If only I could find some way to seal this to stop the leaking. This stuff did the trick. It is white, and a very thick consistency. Formed a perfect seal and in addition holds very strong. It sticks to everything including your hands so be careful. Bought another tube for just in case. Unused product will stay usable in the tube for a while, but for longer term, you may want to place it into another very air-tight container. Highly recommended. ## Frequently Bought Together - Loctite PL Marine Fast Cure Adhesive Sealants, Waterproof Construction Glue for Fiberglass, Vinyl, Glass & More - 3 fl oz Cartridge, Pack of 1 - Dicor BT-1834-1 Butyl Seal Tape - 1/8" x 3/4" x 30' Repair Tape for RV, Trailer, Motorhome, Window, and Vent Sealing - Dicor 501LSW-1 HAPS-Free Self-Leveling Lap Sealant for horizontal surfaces - 10.3 Oz, White, Secure, Ideal for RV Roofing, Maintenance, Repair, Appliance Application --- ## 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.tn/products/713324995-loctite-pl-marine-fast-cure-adhesive-sealants-waterproof-construction-glue](https://www.desertcart.tn/products/713324995-loctite-pl-marine-fast-cure-adhesive-sealants-waterproof-construction-glue) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-20*
