Related Articles. It isn't recommended by plumbers, and it doesn't work for plastic pipes, but you can temporarily stop a water leak in a metal pipe with epoxy putty

epoxy putty

Epoxy putty refers to a group of room-temperature-hardening substances used as space-filling adhesives. Exact compositions vary according to manufacturer and application. They are stored until use as two components of clay-like consistency.

Is J-B Weld stronger than welding?

Than J-B Weld Epoxies. J-B Weld, known as "The Original Cold Weld," was developed as an alternative to traditional torch welding. It's designed to be extremely effective in even the harshest environments. Because it's a two-component (or 2k) epoxy system, it uses reactive chemistry to create the strongest bond possible ...

Is JB cold weld waterproof?

Can J-B Weld be used on exhaust pipe?

JB Weld ExtremeHeat is perfect for making repairs on all manner of high-heat parts, including exhaust manifolds, mufflers, catalytic converters, exhaust pipes, engine blocks, fireplaces, smokers/fireboxes, and many more crack-prone items.

Can you use epoxy underwater?

Marine Epoxy is a permanent, waterproof adhesive. The 2-part formula is ideal for projects requiring high bonding strength on surfaces exposed to water immersion. The adhesive can be applied and will cure underwater. It can be used on glass, metal, wood and other common materials.

How much pressure can a weld hold?

A common rule of thumb is to limit load to 10 KSI on mild steel parts [including welds].

Can you weld a tank with water in it?

Can you weld or solder a hot water tank? Yes, you can weld a hot water tank with a MIG or TIG welder, but a stick welder will not work well on the tank's thin metal. Soldering should only be performed on the copper pipes connected to the tank but cannot be used on the tank itself.

Can J-B Weld fix a radiator?

VERSATILE & DEPENDABLE: Great for radiators, washer fluid tanks, storage tanks, water tanks, plastics, composites, PVC and more. Professionals, mechanics and avid DIYers know J-B gets the job done.

Can you use J-B Weld on cylinder heads?

You can't bloody J-B Weld a cracked cylinder head.” However, to my surprise, one of them said, “That could work if you get the area dry and clean enough. I'd advise flushing both sides of the crack—inside and outside—with brake cleaner, then heating it with a torch to draw out and burn off any residual oil.

Will J-B Weld catch fire?

well, theres a few things to keep in mind about jb weld... first, its an epoxy base, and epoxy is a thermoset plastic, meaning that it cures once, and does not melt down again very cooperatively, so if it gets too hot it would likely catch fire instead of melting away....

Is J-B Weld better than epoxy?

Weld was accualy better than epoxy. Not price wise, but its quality. JB Weld actually is stronger, but not enough to make it worth it. It's very hard to get smooth.

Will J-B Weld work on copper water line?

Can you apply multiple layers of J-B Weld?

JB Weld can be applied in layers. Just clean the surface thoroughly, apply the JB welding, and wait at least 8 hours to re-apply. When applying additional layers, it's important to wait to apply until the first application is fixed.

Should you clamp J-B Weld?

If you can clamp it together, that is a good idea. If not, just hold it together. The epoxy will be fully set in four hours at room temperature. If it is below 40 degrees, it will take longer.

What is compressive strength of epoxy?
