In that situation I would leave them as isOk thanks. Is it absolutely necessary to do? The majority do sit proud, however only very slightly. Wouldn’t a relatively thick layer of adhesive cover them, or are there problems caused by that? (Apologies, I’m not clued up on the implications).
I only ask as there are literally 100 screws to do and because the majority have done into metal studding (gypframe in new build) I am worried about disturbing the ‘grab’ that the screw has made into the metal. I don’t want to risk my current, very sturdy walls unless I have to.
