## Overview

J-B Weld 50172UK MarineWeld is a high-strength, two-part epoxy adhesive designed for permanent repairs on multiple materials including metal, wood, and composites. It cures white, sets in 20 minutes, and fully cures in 15-24 hours, maintaining full strength even underwater. Resistant to water, chemicals, and UV, it’s ideal for marine and outdoor applications requiring durable, waterproof bonding.

## Description

MarineWeld™ is a specially formulated two part Cold-Weld™ adhesive system that provides strong, lasting repairs for bonding different or similar surfaces, such as metal, composites, fiberglass and others. At full cure, its color is white. It may then be shaped, tapped, filed, sanded and drilled, retaining full strength above or below the waters' surface.

Review: Superb - best waterproof/outdoor two part glue/filler on the market. - The best glue/filler of its kind, this stuff cures rock solid, with decent work/cure time, and easy to use. Recommend you mix in small quantities, as it sets quickly and becomes lumpy in doing so, if you keep trying to mix it. Superb at its “job”, though, especially for water features (this was a repair to my mother-in-law’s broken water feature, results are perfect!).
Review: Really good product - Snapped my toilet where the lid goes on and plan to refurb bathroom so decided to try fix it for now. Didn’t think it was going to work but it has! Brilliant Full set time 24 hours Could probably carve back neat

### ⭐⭐⭐⭐ does not work on all surfaces, smells awful but does work well on others.
*by C***Y on 20 September 2019*

I will explain what i bought it for, how it worked, or not, and what I mean by the smell..... I bought this to fix the loo seat onto the loo and it sort of worked... the loo seat is strange, unlike the usual nut/bolt to hold it onto the loo, it has a hexagonal plastic head with a thin body that goes through the fixing hole and a plastic bottom to stop it pulling through - all one piece. This hexagonal head then slots through a slot on the bottom of the loo seat and has a rubber suction foot which also works to stop the hexagonal head sliding out of the slot on the loo seat. with me so far... OK, SO I tried super gluing and all sorts before resorting to epoxy. having use epoxy before I wanted a waterproof one so that the loo seat could still be cleaned regularly. This product did not stick at all to the rubber foot, which I had decided needed fixing as it had split. This product did not stick at all to the ceramic base of the loo ( glossy surface) it set and popped right off. This product DID stick to the plastic hexagonal head and the inside of the slot on the loo seat ( plastic). so - the loo seat is attached a gain, and if the epoxy holds, I do not need to worry that the rubber foot being split will let the hexagonal head slip out, as it is firmly stuck in place ( for now) I am surprised that it did not stick to the rubber foot, I have used epoxy to stick rubber to glass before and it worked well, perhaps rubber to rubber does not create a good bond? and finally - the smell - oh the smell. Epoxy has always had a chemically smell and sometimes a slightly fishy smell, but this stuff has a really really strong and unpleasant mix of rotten fish and burnt hair - really bad, it took 2 days of having the bathroom windows open to get it out, although it was much less strong the second day, but fair warning - using it indoors is probably not what they had in mind for this stuff and you pay the smelly price for it. I hope this helps.
