How to Sand Semi-Gloss Paint

Jonae Fredericks

If you have ever painted a piece of furniture with semi-gloss paint, only to realize that you are unhappy with the shine that semi-gloss paint produces, there is a solution. You can remove the undesirable sheen without the hassle of repainting the entire surface, by applying a light sanding to the finish of the paint. Sandpaper can reduce the shine, and leave your furniture with more of a matte look that will be more esthetically pleasing.

  1. Clean the semi-gloss paint well with a heavy duty cleaner that is capable of removing any dirt, grease, or grime that may have accumulated on the painted surface. A good cleaning will make sanding the semi-gloss paint easier.
