Apply Duco Paint On MDF

Here you will do a series of steps. They include the following:

Apply Duco Paint On MDF

Apply shellac polish on a clean MDF surface:

Before you apply wood Duco on MDF, make sure the surface is clean. With your Dhoti, wipe the surface until it is clean. Next, make shellac polish using some two ingredients: lakh dana and spirit. Then apply the low-density polish to the cleaned surface three to four times. Use your compressor machine to do a fabulous job.

Do repairs:

Shellac polish applications help expose cracks and other defects on wood. Therefore, you will repair these issues in this step. With a putty knife, fill these cracks and dents with wood filler. After the filler dries up, use the 180-grit sanding paper to smoothen the repaired areas. Sweep dust particles using a piece of cloth.

Apply the first primer coat:

Blend our paint thinner and primer surfacer in the ratio of 1:1.5. Note that you have the white and grey primer surfacers. If you choose a darker tone top paint coat, use a grey primer surfacer. If your topcoat color is bright, choose a white primer surfacer. Use your spray gun to apply this first coat of primer to the surface. After about thirty minutes, the primer will be dry.

 Inspect the MDF and repair minor problems:

Step two entailed repair work. That repair work was not enough. After applying the first coat of primer, you might notice tiny imperfections. The repairs will ensure that your Duco finishing is error-free and cute. Use your Duco NC putty to fill the cracks and dents and wait until they dry. After that, use an emery paper with grit quality of 220 to do wet sanding on the filled area. Clear dust with your dhoti or another cotton rag.

Apply the next primer layer:

Now apply the Duco primer to the area you have just repaired. Apply a second layer of the same in the ratio of 1:1.5.

Repeat the wet sanding step:

Next, use your coarse sanding paper (220) to do wet sanding where you have primed. Then, use the grit 320 to finish up the sanding process. After that, the surface will be super smooth and ready to receive Dupont Duco paint. Wipe off the dust with your Dhoti cloth and do the next step.

Apply two coats of Duco Paint:

In the ratio of 1:2, mix your preferred color of Duco NC and thinner. Wipe the surface again with your tack cloth to make it spotless. Paint the first layer of Duco on the MDF. Let it dry for thirty minutes. In the beginning, we said that Duco Paint dries very fast, and you will notice that in this step. So, apply the next layer of paint in the same manner.

Get rid of the sheen:

If you need the best results, do not jump this step. So, wet-sand the surface again using waterproof coarse(600 grit) paper. After that, scrub the surface  with your grit 800 and grit 1000 respectively.

Apply the final coat of paint:

Using the same ratio of 1:2 apply the last coat. Do this task very carefully to protect your results. If you do, the new Duco Paint on MDF will last longer.

Polish the surface to add gloss:

If you want to achieve a higher gloss appearance, carry out the buffing process. You only need to do it if you want the surface to shine. Otherwise, your wood can retain a matte finish. To create a shiny surface, use a rubbing compound rather than polishing wax.


So far, you understand the meaning of Duco Paint on MDF. Duco Paint works best on wooden surfaces, and it entails a wide assortment of colors. The application requires a professional approach. If you do not have a spray gun, let a professional who has it do the job for you. Alternatively, buy a spray gun and apply Duco on MDF as explained in this article.
