Painting Internal Doors
Most people understand that it is important to repaint external doors on a regular basis to repair weather damage, but interior doors are often overlooked. The truth is that interior doors take a lot of abuse too, so repainting them from time to time with a semi-gloss paint will keep them looking as good as possible.
Painting a Door
The best paint for internal doors is semi-gloss because it is easy to clean and produces a finish that lasts for a long time, but gloss is good too. For the purposes of this guide, we will assume that you are painting a door that is plain, so does not need stripping and sanding. If you are re-painting an existing coloured door, you will need to remove it from the hinges, strip the existing paint and sand the door. For plain doors, you can simply paint the door while it is already hung on its hinges.
Painting Flush Doors
Flat doors are the easiest to paint, since you can simply use a roller. Be sure to back brush immediately with a wide brush to get rid of the texture that the roller produces. If you are painting a door that has a luan mahogany veneer, then you may want to sand in between coats to try to smooth the finish. A birch door should already have a smooth finish.
Painting Panelled Doors
Raised-panel doors are more time consuming to paint. Start by filling in the panels, working in the direction of the grain of the wood. Next, paint around the panels. Make sure that you cut in carefully when painting the panels, so that you don’t get paint on the stiles, rails or mutins. This will ensure that you get a smooth finish and even colour. If you allow the paint to run to other areas, then you will end up with clear, unsightly edges. Some people find that using a paint conditioner will help to produce an even finish, because it ensures that the paint stays wet for longer. The wet edge allows you to lead in more easily when starting a new section.
