J-B Weld J-B Stik epoxy putty stick 2 oz

Versatile Repair Putty

J-B Stik is a two-ounce epoxy putty stick designed for bonding metal, ceramic, and concrete surfaces. The dark gray material cures fully in one hour and remains stable between 32 and 350 degrees Fahrenheit. It is machinable and paintable after curing, offering corrosion-resistant repairs for automotive, plumbing, and household tasks.

Faster Alternative to Liquid Epoxies

The stick format eliminates mixing cups and stirring, providing a five-minute working window before the material sets. This jump is worth it when a quick, permanent fix is needed on vertical or overhead surfaces where liquid adhesives would run. The putty fills gaps and rebuilds missing material without sagging during the cure cycle.

Simple Hand-Knead Application

Cut off the required amount, knead until the color is uniform, and press into the prepared surface. Common issues include insufficient kneading leading to weak bonds, applying to dirty or oily substrates, and exceeding the five-minute working time before positioning. Wear gloves to avoid skin irritation from the uncured epoxy.
