How to Paint Plastic Wall Panels

Plastic wall panels are more practical, as they are easier to maintain and repair. Plastic wall panels can be painted, but the process will be different from painting wood or metal panels. Following these steps will ensure that the wall panels will look their best.

You Will Need:

  • Adhesive tape
  • Sandpaper or power sander
  • Adhesives or resin for plastic materials
  • Primer
  • Wall paint and a clear coat paint
  • Detergents or diluted apple cider vinegar
  • Grease remover
  • Paintbrushes
  • Sponges
  • Old newspapers

Step 1 – Sand the Wall Panel

Use sandpaper to make the area smooth. Opt for garnet sandpaper, as this is more resistant and will give you better results. A 300-grit sandpaper will be ideal for plastic surfaces. Use circular moves and move your way from one side to the other, making sure to sand the entire surface.

If you have a power sander, you can save some time.

Step 2 – Clean the Panels

After sanding the panels, you should use some detergent or diluted apple cider vinegar to remove possible remaining stains, dirt and dust from the panels.

Step 3 – Isolate the Area to be Painted

Use adhesive tape to put around the edges of the panels to be painted. Place some old newspapers under the panels, so that paint won’t drip on the floor.

Use some grease remover to eliminate any grease from the area (i.e. caused by your fingers) to ensure the surface is clean and there won’t be bubbles forming under the applied paint.

Step 4 – Spray Adhesive or Resin

Get a spray can of adhesive or resin and apply it on the plastic panels. Allow the areas to dry for up to 1 hour.

Plastic is more difficult to paint than wooden boards or other surfaces, so the adhesive is needed to ensure the paint will remain on the panels for a longer period of time.

Failing to apply adhesive will result in the peeling off of the paint within a few weeks after painting the plastic panels.

Step 5 – Apply the Primer

A primer will be applied on the plastic panels. Allow the primer to dry for 1 hour or as indicated on the label.

Clean the area with grease remover and leave for another 10 minutes.

Step 6 – Paint the Plastic Panels

Get a larger paintbrush and start from the top of the panel, making your way to the bottom. Perform linear moves from one side of the panel to the other until you reach to the bottom of the panel.

Allow 30 minutes (or as indicated on the label) to dry. Test if the paint is dry before applying another coat of paint. Don’t use paint thinner, as this can damage the plastic.

Step 7 – Apply the Clear Coat Paint

A clear coat paint will also have to be applied to protect the paint. Allow a few hours to dry.

After the paint is dry, remove the adhesive tape.
