Reply to comment by bms42 in Pull-up bar broke out of the wall. How do I actually secure it on a sandy stone wall? by Toitonic

Interior load-bearing wall, not wood framed as far is I know. It's not my house and there is a wallpaper on it so I can't really get a good look on it other then through the holes I drilled. The dust coming from it is red in color (kinda like rust). I can scrape off part of the surface easily with a metal tool so it's pretty soft. The house was build on the 1950s in Germany if that helps.

Edit: just googled wood framed facade and I am pretty sure it's not. The holes are about 10-15 cm deep and even at the end of the hole there is still stone. So it's probably mortared bricks

Probably a brick wall then. You'll want some kind of expanding metal anchor to insert into holes you drill. Don't try to use the existing holes, don't drill new holes within 6 inches of the old holes.

I don't really have another place to put it so would you say component mortar would be suitable? I just googled a bit more and it's definitely brick.

Personally I wouldn't trust it. You've compromised the bricks in those locations already. Brick is very brittle, it's difficult to mount to properly.

Alright thanks a lot for the advice. I will try the mortar cause I have no other choice unfortunately but I will take care when doing the pull-ups. And when I deal with brick walls again I know what to do from the start.

I'd be tempted to drill the existing holes out a little larger and epoxy large wood dowels into the voids, then predrill and lag bolt into those. Like 3/4" dowels.

Definitely an interesting idea. But wouldn't the epoxy Drip out of the hole cause it's liquid? Or would you seal the hole with tape while hardening the epoxy? I will also drill the holes bigger in the back either way (mortar or epoxy) to make the sealant itself like a dewel.

The hole would mostly be full of dowel. Tape the opening during curing.
