Hi there, I'm new to home improvements, I apologise for the silly questions! I painted my skirting boards yesterday and discovered there is quite a gap between the board and the wall. I'm going to get some caulk to fill in the gap, but since I already painted the board with wood paint (it was primed already), will the caulk stick? Will I be able to paint over it? Do I need a specific caulk to paint over or can it be any? The same issue is with my new door frame - there is a gap between the frame and the wall. Can I caulk that part too? Thank you.
