  • 1 Before you begin cover the area your working in with a dust sheet. To find the guideline for your wall and ceiling read the manufacturers instructions or simply hold a small section of coving in place and mark along the top and bottom with a pencil. Do this in regular intervals around the room.
  • 2 Then tap a panel pin onto the bottom mark at one corner.
  • 3 Wrap a chalk line around the panel pin and extend to the other corner where you marked. Ensure that the chalk line is taut and lined up correctly from your marks. Then simply pull the chalk line out from the wall and let it snap back into place.
  • 4 Tis will leave a mark across the wall which is now your guideline for coving. Alternatively use a spirit level to join up the markings giving you a frame for where the coving will be.
  • 5 Remove all traces of soft distemper, loose plaster, wallpaper or flaking paint from the wall and ceiling surfaces between the guidelines. Run a multi-purpose detector along the area and mark the position of any wires or pipes.
  • 6 Score the wall and ceiling between these lines with a utility knife. This will provide a key for the adhesive.
  • 7 Start on the longest wall. Measure and cut a length of coving.
  • 8 When measuring and marking each length of cove always measure along the wall guideline. Transfer the measurements taken from the wall onto the back of the cove marked 'wall edge' and mark the position of the cut required, marking up to the lip of the cove.
  • 9 If your longest wall requires more than one length of coving to cover it, simply butt or mitre join two pieces of coving together and fill the gap with adhesive.
  • 10 Lightly sand the edges after cutting to get rid of any rough edges.
  • 11 To fix the coving in position, spread a 'wedge-shaped' band of cove adhesive generously onto the back of the wall and ceiling edges of the cove. You don’t need to do the middle section of the cove, as this will not be in contact with any surface. Position the cove between the guidelines and push firmly into place. Use a damp cloth or paint scraper to wipe off any excess adhesive. Top Tip:Tap panel pins at 600mm intervals into the wall and ceiling either side of the coving. This will provide additional support while the adhesive sets.
  • 12 To find the correct measurements for the corner pieces of coving measure the distance from the corner to the coving already in position on the wall. Add a little extra to allow for pairing down. Transfer these measurements onto your next piece of coving.
  • 13 Saw your piece of coving as per measurements and once finished bring back to the wall to make sure you are happy with the finished result before you apply your adhesive.
  • 14 For internal corners, use a mitre box and saw to create a 45-degree angle at the end of each length of coving. For the right hand piece of the corner saw from the bottom left to the top right. Ensuring that the ceiling side of the coving is at the bottom of the mitre box and that the wall edge is against the side furthest away from you. Make sure you are satisfied with the cut before applying the adhesive and sticking to the wall. Then apply adhesive and stick to wall.
  • 15 For the left hand piece of the corner, place the coving in the mitre box and saw from the bottom right to the top left. Again ensure that the ceiling side of the coving is at the bottom of the mitre box and that the wall edge is against the side closest to you. On an internal corner the wall face is always the long end of the mitre, and on the external the wall face is always the short end of the mitre. Then apply adhesive and stick to the wall.
  • 16 For an external corner, again use a mitre box and saw to create a 45-degree angle at the end of each length of coving. For the right hand piece of the corner saw from the bottom left to the top right. Ensuring that the ceiling side of the coving is at the top of the mitre box and that the wall edge is against the side closest to you. For the left hand piece of the corner, place the coving in the mitre box and saw from the bottom right to the top left. Ensure that the ceiling side of the coving is at the top of the mitre box and that the wall edge is against the side furthest away from you.
  • 17 On an internal corner, the wall face is always the long end of the mitre and on an external corner the wall face is always the shorter end of the mitre. Top Tip: You can buy specially designed corner pieces of coving if you want to a avoid having to make the corner joints yourself. Simply apply adhesive to the back and push into place. Wipe away any excess adhesive.
  • 18 When you have completed fixing the coving, fill in any gaps in the joints or mitred corners with the adhesive then wipe with a sponge. You can lightly sand these joints later for a smooth finish. Additional information: Before you paint the coving it must be sealed with a Cove Primer which you simply brush on. Then you would generally apply a matt white emulsion to match the ceiling.
