Will JB Weld adhere something to concrete?

Question

I need to figure some way to hang a portrait on concrete without actually putting a hole in it. The portrait is heavy and I know JB Weld would most likely hold but I'm not sure if it'll actually adhere it to the wall.

Answer 1

It will hold, at least for a while. Unless the spot you apply the JB is perfectly spotless free of dust and all that, it will eventually fail. Your best bet is a concrete anchor such as a Redhead, but if you choose not to drill into the concrete, than I would suggest liquid nails over JB weld. Granted this will become a permanent application, so if one day you need to remove it, expect to lose the backing of your portrait, and also expect to have some fun scraping the wall.

Answer 2

look on the package!, if iam not mistaken, it will adhere to cement, and most other stuff too.

Answer 3

i wouldn`t trust jb weld , you need a concrete anchor in the wall ,just one small anchor would do the trick ,also you could drive a concrete nail in the wall .I got some short ones that i used to hang all my picks and stuff in my office.They hold alot more than you think .
