Before you start
Wall and ceiling surfaces should be flat and free from undulations. Internal and external corners should be square. Variations in wall and ceiling surfaces or corners may result in gaps and difficulties with adhesion.
- Coving lengths
- Pre-cut internal and external corners
- Coving adhesive (water based)
- PVA adhesive
- Tape measure
- Long spirit level
- Mitre box
- Fine tooth panel saw
- Sealant gun
- Retractable knife
- Fine grade sandpaper
- Paint brush
- Panel pins
- Check the ‘extension’ and ‘drop’ of the coving. These dimensions are shown on the front of the packaging.
- Go around the room the room and draw 2 sets of marks (wall and ceiling) according to the ‘extension’ and ‘drop’ dimensions, at 500mm intervals.
- Join up the marks using a long spirit level, so you have one long continuous horizontal line around the room on the wall and another line around the ceiling. These will be your guidelines for fixing the coving.
- Ensure the area between the lines is clean and free from dust, loose plaster and flaky paint.
- Prime the surface between the lines with PVA adhesive and allow to dry.
- Score the wall above the line with a retractable knife to provide a ‘key’ for the adhesive.
- Start at an internal corner. Ensure the corner pieces are the right way up. Apply a generous line of coving adhesive to the back of the corner piece where it will come in contact with the wall and ceiling. Align with the top and bottom lines and press each piece carefully into position.
- Apply a generous line of coving adhesive to each length along the top and bottom contact edges. Tip: Use enough so that a little will ooze out and help to fill any small gaps.
- Align the coving length with the lines on the wall and ceiling. Work your way along, carefully pressing into position.
- It is a good idea to lightly hammer panel pins into the wall and ceiling to hold the coving in place whilst the adhesive sets.
- If a long wall means you have to join two lengths coving together, make a pair of 45 degree mitre cuts in the same direction, so that the two sections meet at a mitred joint.
- Lightly mark the intended direction of the mitre cuts.
- Firmly secure the mitre box to your workbench. Place the coving into the mitre box with the wall edge at the top of the box.
- Use a fine toothed panel saw to make the 45 degree mitre cuts in the marked direction. If needs be, lightly sand the cut ends until smooth.
- Apply adhesive to both mitre cuts and then join.
- Fill in any remaining narrow gaps between adjoining pieces of coving or between the coving and the wall or ceiling, by squeezing in a little extra adhesive.
- Carefully remove any excess adhesive with a scraper and then wipe with a clean damp cloth.
- Carefully remove panel pins when adhesive has dried.
- Allow 24 hours after installation before painting the coving. Use a water based emulsion.
