How to Repaint an Old Piano

Repainting a piano is the same as repainting any other piece of wooden furniture.

Over time any wooden painted object is going to show signs of wear as the color chips or peels away. The same is true of pianos, especially if they are moved around regularly or used for recording sessions. Repainting anything wooden involves the same basic process and a piano is no different, but you must take extra care to ensure paint doesn't get on areas where it is not wanted.

Things You'll Need

• Electric sander
• Coarse grit sandpaper
• Fine grit sandpaper
• Primer
• Paint
• Paintbrush

Instructions

1. Cover the keys and pedals with painters tape, newspaper or a waterproof sheet to avoid drips of paint and dust getting in the piano. A waterproof sheet on the floor is also a good idea.

2. Fit a piece of coarse grit sandpaper to an electric sander and go over the wood to remove the last paint layer. It is possible to do this by hand, but using an electric sander is quicker.

3. Replace the coarse sandpaper with fine grit and go over the piano again to seal the grain.

4. Apply a layer of wood primer using a paintbrush to the areas of the piano intended for painting. Paint on the primer in thin layers with the brush strokes all going the same direction. Priming is an essential step to ensure the paint bonds well to the wood. Let the primer dry overnight.

5. Paint the piano in a desired base color. Oil- or water-based paints are suitable here as long as they are specified for use on wood. Oil paints will give a harder finish that can protect the wood better. Let it dry overnight and apply a second and third coat to ensure even coverage. Allow each coat to dry completely before applying the next.

6. Touch up more delicate areas of the piano with a detailing brush. For example the key slip, the piece of wood in front of the keys, is best done with a small brush so no paint gets on the keys.

7. Apply a second and third color to add details to panels of the piano if desired. Before painting, apply painters tape around the area where you will apply the alternative color so the colors do not mix.

Tips & Warnings

• A layer of aerosol lacquer could also be applied afterward as an extra layer of protection, but this is only necessary if you will be moving the instrument around often.

• Apply the paint and primer in thin layers to avoid getting any drips inside the piano that may affect the mechanism.

• Lightly sand between coats to remove imperfections in the paint. This is only necessary if there is an obvious drip mark or if you are applying high gloss paint.

• Always wear a face mask when sanding wood to prevent inhalation of sawdust.

• Prime and paint the piano in a well ventilated area.
