I'm interesting in hanging a bike hook up on my patio outdoors. My outdoor walls appear to be some kind of hard stucco, and I've run a magnetic stud finder over the whole wall and it's all magnetic, indicating to me that there's some kind of metal mesh underneath. Ideally I'd like to hang the hook high enough off the ground on the wall such that the bike doesn't rest on the ground, but if it's significantly easier to hang it such that I don't put that much weight on the hook I can do that.
What is the best way to drill into the wall and hang the hook? I have diamond tipped drill bits. I'm just not sure if there's some kind of plywood underneath or if I will hit the metal when drilling. Will I need some kind of expanding screw holder or will the wall be strong enough to hold the weight of the bike?
EDIT: Apparently I shouldn't be trying to damage my outdoor stucco, so it looks like I will be trying to find another way to hang the bike.
