SC-05Glue and fix the cover strip to the right wall typeApply grab adhesive in a zigzag along the back of the strip and press it firmly onto the old skirting, holding or wedging it for the time stated on the tube. While it cures, add a few mechanical fixings through the strip and old skirting into the wall for extra grip while the glue goes off - the fixing depends on what's behind: into a timber stud, use a 40mm wood screw straight into its centre; into a metal stud, use a self-drilling metal-stud screw or hollow-wall toggle, never a plain wall plug or ordinary wood screw, as these strip straight through 0.5mm steel; into solid brick or block, drill 6mm and use a wall plug with a 40mm screw; through dot-and-dab plasterboard, use a fixing long enough to pass through the dab and bite into the masonry behind, not just the board; and through lath and plaster, avoid fixing into the lath itself and aim for solid masonry behind it to stop the lath cracking.
