To calculate how much coving you need to order, simply follow these steps:

1. Measure the perimeter of your room in metres as accurately as possible.
2. Add 10% to that measurement to allow for wastage when cutting around corners.
3. Round the total up to the next whole metre – this is the amount you should order.

For example, if your room’s perimeter is 23.2 metres, adding 10% (2.32 metres) brings the total to 25.52 metres. Rounded up, you would need to order 26 metres of coving.

Please NOTE: if the coving presents an elaborate pattern, then the waste should be increased to 15-20%

All decorative plaster products, whether it is coving or ceiling roses, should be stored flat. If storing your decorative plaster upright, make sure it is well supported in order to prevent sagging or bowing. Decorative plaster products may still have some residual moisture in them, so we strongly recommend that you do not store them on carpets, furniture or timber flooring. After placing an order you will be sent care sheets by email. You should read these very carefully as they contain important information on storing and handling your decorative plaster mouldings.

Coving should be cut with a standard, sharp, medium toothed, cross-cut saw in order to achieve the best results.

If using a mitre box, it should have a backplate that is high enough to accommodate the size of the coving you have. Any mitre boxes or chop saws that are designed for making picture frames will not be suitable.

Removal of paint can be carried out using water, steam, chemical removers or wallpaper stripper. These should always be tested on a small unobtrusive piece of plaster first. Scrapers can be used to gently remove the layers of paint, and toothbrushes are good for getting into the finer detail. Never use sanders or wire brushes; these will damage your decorative plasterwork.

If you own a listed Period Property you should consult with your local authority’s conservation officer before removing the original paint layers, as these may hold a unique historical record of the original paint.

Yes you can but it is important to follow some guidelines to get a great finish. Firstly ensure that the coving has dried completely. There may still be residual moisture in it from manufacture. 3-4 days should be sufficient for it to dry.

Start by applying a 50% water 50% emulsion mix to the coving first and allow this to dry. Once this base coat has dried apply your chosen colour. As coving has a smooth surface small brushstrokes with a polyester brush will give you the best finish.

We recommend using an adhesive specifically formulated for gypsum surfaces. Once your order is placed, we will provide comprehensive installation instructions, including a detailed guide on how to properly install the coving.  For optimal installation, we recommend using brass screws to temporarily secure the coving or ceiling rose while the adhesive sets. Ensure the screws are of sufficient length to pass through the coving and anchor into the wall. Once the adhesive has fully cured, fill any screw holes with a fine surface filler, then sand smooth before proceeding with painting.
