How to Paint a Glazed Interior Door

Updated April 17, 2017

Interior doors can be heavily used, and this may lead to marks and chips on the paintwork. Repainting a glazed interior door may seem a daunting prospect because of the risk of splashing paint onto the glass. However, with careful preparation and masking tape you should be able to achieve a neat finish.

Place a dust sheet under and around the door to protect the carpet or flooring under the work area.

Fill a bucket with hot water and around 3 dashes of dish detergent. Dampen a clean cloth and wash the woodwork of the glazed door thoroughly. Wait for the woodwork to dry.

Apply masking tape around the edges of each of the interior door's glass panes. Use 2- to 3-inch-wide masking tape. Press the tape neatly against each edge to form a neat border with the woodwork. Cut away any excess masking tape with a utility knife. Cover the door hinges with masking tape to prevent them from gluing up with paint.

Sand the old paintwork on the door frame with 220-grit sandpaper. Wrap the sandpaper around a sanding block to make handling easier, or use a palm sander. Sanding will remove loose paint and also help the fresh paint to adhere to the surface.

Apply a stabilising wood primer to the sanded wood. This prevent sap and oils leaking from the wood and staining the new layers of paint. Use a 2- to 3-inch paintbrush to apply an even layer of primer. Wait for the primer to dry. This usually takes two to three hours, but check the manufacturer's instructions to be sure.

Paint the wood with an oil- or acrylic-based wood paint, using a clean 2- to 3-inch paintbrush. Paint in the direction of the wood grain. Wait for the first layer to dry, then apply a second coat for a long-lasting finish. If you use the same brush, clean it first with white spirit or turpentine.

Pull away the masking tape gently but firmly after the paint has dried for at least 24 hours.

Tip

Use blue masking tape to help you easily spot the border between the woodwork and the masked areas.

Warning

Wear a dust mask while sanding. Wear protective gloves when handling and using paint primers.
