Can I Paint Over Polyurethane?

Polyurethane is a type of clear coat that is often used to protect wood surfaces. It can create a shiny, durable finish that is resistant to scratches and stains. While polyurethane is typically applied to bare wood, it is possible to paint over it.

Painting over polyurethane can be tricky, so it’s important to take the necessary precautions to ensure that your paint job will turn out well.

  • Clean the surface: Polyurethane can be difficult to paint over because it is often slick and nonporous
  • For this reason, it is important to thoroughly clean the surface before beginning any painting project
  • Use a mild detergent and scrub the area well with a sponge or brush
  • Rinse completely and allow the surface to dry completely before moving on to the next step
  • Sand the surface: Once the surface is clean, you will need to sand it in order to create a rough surface for the paint to adhere to
  • Use medium-grit sandpaper and sand evenly over the entire area
  • Be sure to wipe away any dust that accumulates during this process
  • Apply primer: Primer is essential when painting over polyurethane because it will help the paint adhere better and provide a more even finish overall
  • Choose an oil-based primer for best results and apply it according to the manufacturer’s instructions using a roller or brush designed for use with oil-based products
  • Paint: Now you are ready to start painting! Choose an oil-based paint in your desired color and apply it evenly over the primed surface using a roller or brush made for use with oil-based paints

Water-based polyurethane dries quickly and has little odor, but it may not be as durable as oil-based polyurethane. You can paint directly over either type of polyurethane with latex or oil-based paint, but you must use a primer first.
