I used to have some (guitar) hooks which were screwed into a brick wall, but 2/3 of them have fallen out. My only guess is that (since they are all at the same vertical height) they all went into a line of mortar rather than brick? Anyway would like to put them back up, and for them to stay up this time. I don't think the original holes are salvageable, they've become quite enlarged, and unhelpfully filled by yours truly.
My plan is to screw and silicone adhesive a wooden batten to the wall and then screw the hooks into the wood. I'm thinking sand and varnish a 18x69mm spruce batten, use 4 chunky screws and wall plugs and a healthy dose of silicone adhesive to hold the batten to the wall, and finally some small screws to hold the hooks to the batten (the holes in the hooks are small, and the wood is thin, so the screws have to be both small and short).
I just want to check that I'm not missing anything before I permanently butcher my wall, and ask whether it's okay for the screws holding the hooks to the batten to go all the way through the wood, because the screws that came with it are just slightly too long. 3 guitars would weigh about 10kg in total for reference.
