How Soon Can You Paint Over Jb Weld
JB Weld is a two-part epoxy that can be used to repair many different types of materials, including metal, plastic, and glass. It can also be used to bond two pieces of material together. While it is a strong adhesive, it is not meant for permanent repairs.
This means that you can paint over JB Weld once it has cured, but the repair may not be as durable as if you had used another type of adhesive.

Is J-B Weld a Permanent Fix?
J-B Weld is a two-part epoxy that can be used to repair everything from cracked plastic to leaking radiators. It’s strong, durable and sets in just 4-6 hours. But is it a permanent fix?
The answer is yes and no. J-B Weld is designed to be a permanent repair, but it’s not necessarily invincible. It can be vulnerable to heat and chemicals, so it’s important to take care of your repairs and not put them through too much stress.
With proper care, though, J-B Weld should last as long as the original material it’s bonding together.
How Do You Tell If J-B Weld is Fully Cured?
J-B Weld is a two-part epoxy system that can be used to bond metal, glass, ceramic, wood, and plastic. Once mixed, it forms a permanent bond that can withstand extreme temperatures and pressures. But how do you know if J-B Weld is fully cured?
The best way to tell if J-B Weld is fully cured is to wait at least 24 hours after mixing the two parts together. The curing process will continue for several days, but the bond will be strong enough for most applications after 24 hours. You can test the strength of the bond by trying to pull apart two pieces of metal that have been joined with J-B Weld.
If the bond holds, then it is fully cured.

Conclusion
If your JB Weld is still curing, wait at least 24 hours before attempting to paint over it. For a painted surface, lightly sand the area around the repair to give the paint something to “grab” onto. Once you’ve sanded the area, wipe away any dust with a damp cloth and allow it to dry completely.
You can then apply primer and paint as you would any other surface.
