J-B Weld MarineWeld Syringe 2-Pack, White, UV Resistant, High-Strength & Impact Resistant, 25ml 2-Pack, 50172-2

Great product! Used to seal a couple holes in a large trough. Worked perfectly and has lasted 2 months without leakage containing the water! Have used this for multiple things over the years. And it's always worked easily. The combined tube extractor puts out exactly the right amount to mix eliminating worries of getting the proper 50/50 mix for it to cure properly. Highly recommend for cracks, and holes.

Worked perfectly to repair the outer coiled stainless shower hose connection.

After trying many other products (and also marble repair services) to fix a seam between two slabs (edge between the top and side panels) on a white Marble bath, this one is the perfect solution. It also lasts despite repeated, regular use and does not turn yellow over time like all the epoxy-based products. Highly recommend!

This product sets up well, but not as hard as other epoxies from this company. The packages do not contain a lot of product, but are suitable for smaller repairs, and the adhesion is good. I would recommend it with the caveats above.

I use this to fix chips in my boat gel coat. Permanent fix

Great product, and not limited to being, simply, an adhesive; it's also a great fill for fiberglass dings and even PVC cracks, etc. I was able to use it successfully on 3 different composites on my canoe- What other product can do this?

FYI...I think the packaging says "ready to sand in one hour" and they're not kidding. I set up my project, mixed the content inside the two syringes together, and started applying the epoxy working from one end of a crack to the other end. It started hardening on me before I could cover the entire crack. So if you need a little more time, I would buy the stuff that cures in 2 hours.

easy to use. Had 3 chips in my sink and this covered them easily. took about 12 hours to dry hard, but could use sink in 3 hours. now i just have to lightly sand. Was going to get a new bath vanity, and now don't have to!

Muy buen pegamento flexible y a prueba de agua, seca muy rápido toca probar su durabilidad

I got two packets for an important project. When we opened one, one of the tubes was completely solid. Not to worry, I had an extra one, right? Wrong! That one was also in the same condition. So now we are delayed by a week at least until we get another suitable product, not to mention the financial losses .

As described. Great for wet areas.

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!).

Sehr sehr aber gutes Zeug. Da lohnt sich die Lieferung aus England. Gut ausdrückbar gut verrührbar wird nach 40 Minuten gummiartig so dass ich in mein offenes GFK Loch erst füllen und danach nach 40 Minuten mit einer Schraube versehen konnte es hält alles bombenfest. Auf dem Foto mit der Schraube war ein Versuch der Festigkeit.
