Choose the right paint for your MDF project. Latex or other water-based paints are best. Oil-based or shellac-based paints aren’t suitable, as they may cause warping or deterioration. Duco paint is a lacquer type that needs an oil-based primer to bond with MDF. Use latex primer and latex top coats with Duco paint. Check labels to ensure they’re compatible.

Prepare the surface:

  • Clean with warm, soapy water and allow to dry.
  • Remove old paint layers with a wire brush or chemical remover.
  • Sand any damage or roughness with 180-grit sandpaper.
  • Fill in crevices with Bondo or wood putty. Sand lightly after filling.

Now you’re ready to begin painting!

Prepare the surface

Before starting any surface prep, it’s crucial to identify what type of surface you’re working with. It can range from walls painted with oil- or water-based paint to natural stone such as marble, slate, or granite. Each surface type has its properties and needs different preparation methods.

For walls to be painted with oil or water-based paint:

  • Clean using a damp cloth and mild detergent.
  • Fill cracks or holes with spackling compound, let it dry, and then lightly sand with 120 grit sandpaper.
  • Wipe away dust created by rubbing with a damp cloth.
  • Apply one coat of primer to the paint you’re using. Let it dry completely before continuing.

For natural stones such as marble, slate, or granite:

  • Sweep the surface to remove dirt and debris.
  • Damp mop the area with warm water and mild soap solution (if needed). Rinse and let air dry fully before going on.
  • Lightly buff away damaged spots with steel wool or #0000-grade steel wool pads, applying gentle pressure. Don’t press too hard, or it could cause more damage.

Sand the surface

Before applying Duco paint, you must prepare the surface.

  • Sand down the MDF with 120-180 grit sandpaper. Use a pole sander to make it even and flawless.
  • Remove existing coatings from the board. Darker stains may need multiple light coats of stain-blocking primer.
  • Sand after each coat has dried for an even finish.
  • Get rid of dust and dirt with a damp cloth or a vacuum cleaner with an upholstery attachment.

Apply a primer

Are you preparing a surface for painting? Don’t forget to apply primer! Primer protects surfaces from moisture, helps paint last longer, and improves paint adhesion. Usually, one coat is enough. Here are some tips for applying a quality primer:

  1. Choose a water-based or oil-based primer that best suits your surface type (wood, drywall, metal, etc.). Make sure the surface is clean and free of dust and debris.
  2. Apply an oil-based wood sealer to any bare wood areas before primer. High-adhesion primers are also great for blocking stains from coming through.
  3. If using spray cans, tip them upside down for 15 seconds until you hear a hissing sound. Tilt it slightly before beginning the application.
  4. Start with long overlapping strokes, and don’t rush. Keep spraying until the entire area is covered. Avoid heavy lines. Work in one place at a time, allowing each layer to dry fully before adding more coats.

  1. Use coarse-grade sandpaper (120-150 grit) for sanding the MDF.
  2. Wipe the dust off with a damp cloth and let it dry.
  3. Apply one coat of acrylic primer sealer using a brush or roller. Work in the direction of the grain. Let it dry for up to 12 hours.
  4. When dry, apply Duco paint, using long brush strokes in the direction of the grain. Finish with smoother cross-grain strokes if needed.
  5. Apply light coats of paint and let it dry. Be careful not to brush over.
  6. Finally, apply two light coats of clear sealer. This will protect against heat and moisture damage. Let it cure/dry following the manufacturer’s instructions.


Duco Paint is essential for almost any project. Painting kitchen cabinets, furniture, or MDF? Duco Paint will give you a lasting finish. Let’s discuss the steps to applying it on MDF.

  1. First, you must clean the surface.
  2. Then, apply a primer.
  3. After that, apply a coat of Duco Paint.
  4. Finally, let the paint dry, and you’re done!

Allow the paint to dry.

Complete the steps for Duco paint on MDF. Allow the paint to dry. It can take anywhere from several hours to 12 hours. Don’t disturb it while drying. Place it in a sunny spot with little air movement.

Once it is dry, decide if you want protective coatings or sealants. If not, wipe away dust with a soft cloth and warm water. Use a microfiber cloth for the best results.

Apply a top coat

Once you’ve completed prepping your furniture, it’s time to apply a top coat. This will protect it from spills and wear and make it shine and smooth any uneven surfaces. There are various sheens, such as gloss, semi-gloss, satin, and matte. Consider the look you’re going for when selecting a top coat. Glossy finishes create a sparkly look, while matte finishes give a subtle appearance.

Keep in mind the type of woodwork you’re working with. Some woods are sensitive to certain ingredients in certain finishes. Test an inconspicuous area or talk to an expert before starting. Once you’ve chosen the right finish (such as wax, polyurethane, or shellac), it’s time to apply the top coat.

If the project requires stain or paint, wait for each layer to dry before beginning. Start by washing the entire surface with mineral spirits to remove dust particles. Then use fine-grit sandpaper (120-180) to lightly scuff any areas that don’t need to be stained or painted. Apply two coats with small brush strokes, allowing drying time between each. Then use larger brush strokes in an even direction (left/right instead of up/down) for two additional coats. Lightly scuff between the first two and last two layers.

Once you’re done, your furniture will be ready!

Sand and buff the surface

Sanding is a must for a smooth, professional furniture finish. Start with fine-grit sandpaper to remove sawdust and smooth out minor scratches and bumps. Then use sandpaper of increasingly finer grits to get the desired finish. For a high-gloss finish, use spirits from 220 to 400.

Clean off all dust and debris after sanding. This will ensure good adhesion of finishing materials.

Once sanding is done, buff the furniture with a lint-free cloth or a polishing pad. Use light strokes and rotate the place to avoid overloading it with polish or wax. Buffing will make repairs shine, blend them in, and protect surfaces from UV and moisture damage. With proper care, wood surfaces can look great for years!
