1. Remove paint

If your cornice has had many layers of paint applied over the years that are difficult to chip away using a chisel, you’ll need to use a specialist paint stripper for wood to make the job easier. A product such as Peelaway is a great, easy-to-apply solution, as you simply apply the pre-mixed paste to the surface, cover in plastic sheeting and leave for 24-48 hours. Once this time has passed, the paint should come off easily with a chisel.

2. Clean the cornice

Use a light disinfectant spray and a small amount of cold water to clean the surface of the cornice, removing dirt. Use a brush to get rid of dust, too. You may also like to use a sugar soap solution, which will not only clean the surface, but provide a good base for painting.

3. Repair cracks

Original cornice may have become damaged over the years, or you may find cracks that have been covered with paint once you’ve stripped it back.

First, use a small chisel to carefully chip away the edges of the crack, resulting in a more even surface, and then sand away any lumps so that the area is smooth.

Using a spatula or wide chisel, apply a pre-prepared soft filler to the area, filling the crack and smoothing over, so that when paint is applied, the finish is seamless. Make sure to not overload the filler – it’s best to use a little bit at a time and top up with more if required.

4. Refine edges

To make the most of the decorative cornice, restoring defined, crisp edges is key. Using a small chisel or blade, carefully skim along the edge or the front-facing groove first to highlight the corners and right angles, chipping away any excess paint to get a smooth finish. Do the same along the other lines of your cornice, working down to the bottom, but being careful not to chop away too much and compromise the original shape.

5. Clean the cornice again

After refining the edges and applying filler (and waiting for this to dry), clean the cornice with a cloth and clean water to remove dust.

6. Paint

You may like to leave your cornice stripped for a distressed look, but if you’re planning to paint it, use a basic matt emulsion. Apply the first coat, leave to dry and then paint over with a second coat.
