I live in a house built in the mid-60s. I bought a wall mounted pull-up bar (this: https://www.titan.fitness/strength/strength-accessories/pull-up-bars/titan-wall-mounted-pull-up-chin-up-bar/400510.html), with the intention of mounting it on an exterior wall (there are no indoor walls - including the garage - with a high enough ceiling to be able to do muscle-ups).
However, right as I was about to drill, a thought occurred to me: is this is a bad idea? Will drilling into the stucco "break" some kind of weather seal, & exposing my house to mold, mildew, etc?
I'm in Los Angeles, so we don't get that much rain, but the concern still applies.
Edit: I'd be mounting it on the studs behind the stucco, obviously. My concern just had to do with "breaking the seal" of the stucco or not.
