RH-05Remove screws and wall plugsUnscrew the fixing first, never pull it out by the plug. Then remove the plug itself: part-drive the screw back in a few turns and grip its head with pliers to pull the plug out, or push the plug fully into the hole and fill over it later. On solid brick or block, the plug is gripped tightly, so pull firmly and steadily. On plasterboard over timber studs, a plug fixed into the stud is wedged tight, so lever it gently side to side as you pull to avoid tearing the paper face. On plasterboard over metal studs, the fixing is unlikely to be a wall plug at all, it's more likely a self-drilling screw or toggle, so simply unscrew or compress and withdraw it. On dot-and-dab plasterboard, a long plug may reach through to the masonry behind, so pull steadily and expect some crumbling of the plasterboard face around the hole, which is easy to fill. On lath and plaster, go slowly, as the old lime plaster is brittle and can crack in a wide patch if you force it.
