What You'll Learn
Prepare the surface
Preparing the surface of a plastic veneer properly is crucial to ensure the paint sticks well and does not peel off later. Here is a step-by-step guide to prepare the surface of a plastic veneer:
Cover the surrounding area
Protect the floor and surrounding area by laying down a drop cloth or a large piece of plastic sheeting. If the object is too large to move, secure the sheet in place with painter's tape.
Remove hardware
Veneer is often found on furniture and interior decoration items, which may have hardware like handles, hinges, or brackets. Remove these items with a screwdriver and store them somewhere safe.
Tape adjacent areas
Use painter's tape to seal small areas that you do not want to be painted. For larger areas, cover the surface with plastic and tape the plastic in place.
Repair damage
Before painting, it is important to repair any damage such as chips, gouges, or dents. Remove any loose chunks of veneer and sand down the edges around each hole. Fill the holes with wood filler, smooth it out with a putty knife, and let it dry completely.
Clean the surface
Use a mild dishwashing liquid or a grease-dissolving plastic cleaner to wipe down the surface and remove any built-up grease, dirt, or grime. For stubborn stains, apply rubbing alcohol to the stain, wait for 10-20 minutes, and then scrub it away. Rinse and let the surface dry completely.
Sand the surface
Use fine-grit sandpaper or a sanding block to sand the surface and create a rough texture for the paint to cling to. An orbital sander with 220-grit sandpaper can also be used for larger areas, while a sanding block is useful for crevices and hard-to-reach areas. Vacuum and wipe the surface with a damp cloth to remove any dust.
Prime the surface
Apply a thin, even coat of primer suitable for plastic surfaces. Allow the primer to dry completely, usually for about 30 minutes to 1 hour, before proceeding to paint.

Filling chips and holes
Filling in chips and holes in plastic veneer is an easy process. First, remove any loose veneer by gently pulling it up with your fingertip. If it comes off easily, lift the edge and let it chip off. Next, use a razor or sharp utility knife to cut away any remaining veneer above the damage. Then, use a product like Bondo Wood Filler, a two-part epoxy putty, or wood glue to fill in the damaged area. You can also use a burn-in wood filler, which involves melting the filler with a tool like a pyrography pen and dripping it into the hole.
If using a product like Bondo, mix the Bondo base and hardener together on a disposable plate—work quickly as it starts to harden fast. Spread the mixture over the damaged area with a flat-edged tool like a Bondo spreader or a plastic putty knife. You can overfill the area and then sand it down to make it smooth and flat. Let the filler dry for about 30 minutes, then sand it down with 100-220 grit sandpaper.
If you are painting the repaired area, you can use regular Automotive Bondo, All-Purpose Bondo, or Bondo Wood Filler. If you need to stain the area, use Bondo Wood Filler as it dries a natural wood colour. Before staining, scuff sand the area with 220-grit sandpaper to help the stain adhere better. Use a gel stain and let it sit for about 30 seconds before wiping away the excess with a clean rag. Let the stain dry for 24 hours before applying a second coat. Seal the stained surface with oil-based polyurethane to protect it from scratches.

Sanding
Before you begin sanding, carefully inspect the veneer for any damage, such as chips, bubbles, or lifting areas. If you find any issues, repair them first to avoid further damage during the sanding process. You can fill in small chips and dents with wood putty or filler, then sand the filled areas smooth and flush with the rest of the veneer.
When sanding plastic veneer, it's best to use fine or medium-grit sandpaper, such as 220-grit. You can use a sanding block or an orbital sander, depending on the size of the area you're working on. An orbital sander will speed up the process, but for smaller or hard-to-reach areas, a sanding block will give you more control. Go over the entire surface lightly, being careful not to apply too much pressure, as you could accidentally sand through the veneer. The goal is to create a dull, slightly scuffed surface that will help the primer adhere better.
After sanding, it's crucial to remove all the dust created by the process. Use a vacuum to remove the majority of the dust, then wipe down the surface with a tack cloth or a slightly damp cloth. This step is important to ensure that no debris is left behind, which could scratch the surface during the next steps.
Once the surface is clean and dry, you can proceed with priming and painting. However, keep in mind that if you want to stain the veneer, you'll need to be more precise and thorough with your sanding, ensuring a perfectly smooth and blemish-free surface.

Priming
Clean the Surface
Before priming, it is essential to clean the veneer surface thoroughly. Use a damp cloth or rag to wipe down the veneer, removing any dirt, grease, or grime. You can use a mixture of detergent and water or a degreaser like ammonia-based cleaners or denatured alcohol. Ensure you don't oversaturate the veneer with water. After cleaning, dry the surface with an old towel or cloth to remove any remaining moisture.
Sand the Surface
Lightly sand the veneer surface with sandpaper to create a rough texture that will help the primer adhere better. Use fine-grit sandpaper, such as 150-grit or 180-grit, to reduce the risk of damaging the veneer. Sand just enough to scuff up the surface. If there are any repairs or wood filler applied, sand these areas to smooth them out and ensure an even surface. After sanding, remove any dust or particles by vacuuming or wiping the surface with a tack cloth.
Choose the Right Primer
Select a suitable primer designed for use on plastic veneer surfaces. Water-based primers, such as Zinsser Bulls Eye 1-2-3, are a popular choice as they serve as a primer, sealer, and stain blocker all in one. Oil-based primers, such as Kilz primer, are also recommended for their durability and smooth finish.
Apply the Primer
Apply at least two coats of primer to the veneer surface, allowing sufficient drying time between coats. Use a roller for larger, flat surfaces and a paintbrush for edges and corners. Ensure you follow the manufacturer's instructions for drying times.
Sand and Clean Again (Optional)
Some sources suggest lightly sanding the primed surface with fine-grit sandpaper (220-grit) to create an even smoother base for the paint to adhere to. After sanding, remove any dust by vacuuming or wiping with a tack cloth.
By following these steps, you will effectively prime a plastic veneer surface, setting the foundation for a successful paint job. Remember, proper preparation is key to achieving a long-lasting and aesthetically pleasing finish.
