Question: We have sliding closet doors that are in great condition, but their color is way too dark for our decor. Can I lighten these wooden doors and do I have to sand them first?

Answer: Though you certainly could sand the doors, an easier method would be to use a product such as synthetic TSP (tri‑sodium phosphate), also known as “liquid sandpaper.”

The original version of Spic and Span once consisted entirely of–you got it–pure TSP. All you need to do is use it to wash the surface you want to paint.

The TSP will etch the varnish and make the surface porous. This condition improves bonding. After you have thoroughly rinsed away the TSP, all you need to do is apply a really good undercoat.

Keep in mind that cheap paint will not easily hide the darker color you are trying to eliminate. So purchase a good brand. Finally, use the finish coat of your choice.

If you prefer to have a stained rather than painted finish, you will need to sand off the existing finish and then use a wood bleach to lighten the existing stain. Once you have achieved the desired tone, apply two to three coats of clear finish.
