Drilling lots of holes in freshly painted plastered brick/concrete walls.
I had a European builder mate come out for 6 weeks when renovating the villa, and he did a sterling job. All done, flew him back, lubbly-jubbly, guv. Months later I’m now at the stage of having lots of stuff that I want attached to the walls. Attached via drilling into them.
All the walls are brick (presumably) covered with plaster and painted. None of that dry-wall, plaster board cheap-ass crap. Tiz all rock solid, tiger.
I probably want 60 or so holes drilled into these lovely pristine painted masterpieces of construction. Some of them need to be exact.
I have a collection of model Ferraris and have 8 clear 20x10cm floating shelves for them to rest on, that will go into the living room wall. The screws are small, but this needs to be done precisely. 16 small sized holes.
The shelves will be straighter.
