What Will You Need?

You will require the following items to fit your coving without any issues:

  • Lengths of coving
  • Adhesive
  • Sandpaper
  • Mitre Box
  • Spirit level
  • Chalk line
  • Panel pins
  • Filler
  • Hammer

How to Install Coving & Cornice

Step 1: Protect Your Floor

Before you start fitting your coving it helps to protect your floor by laying tarpaulin or a plastic sheet. You could also wear protective gloves to protect your hands and stay safe. These are more precautionary than absolutely necessary.

Step 2: Mark the Wall

Marking lines are required to be added to the wall and ceiling so it’s clear where the coving should be placed. To find out where these should be, read the instructions from the manufacturers as they will provide exact measurements.

If for example the coving should be placed 83mm down the wall and 83mm onto the ceiling (measured from where the ceiling and wall meet) then carry out the measurements and add marks to the wall at these points at roughly one metre intervals. Once complete, use an object with a straight edge to join them (a spirit level would be useful here).

A chalk line can also be used. After the measurements have been carried out and the marks added onto the wall and ceiling, lightly hammer in a panel pin at one end of the wall on one of the measurement marks. Then carefully wrap the chalk line around the panel pin and extend it to the other end of the wall which you have already marked. Double check that your chalk line is lined up accurately and whilst it is pulled fairly tight snap it back in place against the wall. This will give you a clear mark across the wall that will serve as your guideline for fitting the coving.

Step 3: Hammer in Panel Pins

Once you have a clear guideline, hammer in your panel pins every 35/40 centimetres along the chalk line (making sure to check for any pipes or cables beforehand). You should also ensure that the cut section of your coving is in place to ensure proper fitting.

Step 4: Apply the Coving Adhesive

Take your adhesive and apply it carefully to the back of your coving along the edges. You don’t have to apply the adhesive at the centre of the coving since it won’t come in contact with any surface.

Step 5: Fit Your Coving

Carefully lift coving onto the top of your panel pins that you hammered into the wall in step 3 and push it firmly. Make sure that it is in a straight line and nothing gets out of your chalk line.

Step 6: Tidy the Edges

Take your time to get rid of the excess adhesive on the coving. You can accomplish this step using a damp piece of cloth and a palette knife.

Step 7: Apply Filler

Once you have removed the excess adhesive, apply a thick bead of filler to the bottom and top edges of the coving. Use a damp sponge to smooth the filler so that your edges remain clean.

Step 8: Sand the Filler

Allow your filler some time to dry up. Once it has dried up, you can use sandpaper to sand it until it is entirely smooth.

Cutting Coving and Cornice Corners & Mitres

Cutting coving and cornice corners and mitres is slightly trickier however it is still definitely achievable without having to get the professionals in.

For this step, it helps if you have a mitre box. We have 3 different mitre boxes to suit all sizes of coving which are ideal for cutting internal and external corners.

The videos below provide step by step instructions on how to cut the internal and external corners of coving and cornice.

If you need to stop the coving before a staircase slope or you just need to stop at one end then you need to cut a stop end mitre. The video below demonstrates how to do this.
