Dust is a major enemy of MDF

† Make sure that these are completely dust-free and also in the room where you are going to paint.

It is best to use tissues for this.

Please do not use water or ammonia, as these will absorb liquids into the MDF, causing it to expand.

Always choose a water-based primer.

This dries faster and in this way you ensure that the MDF does not get a chance to become sticky, the so-called ‘fish eyes’ (the materials of MDF have no chance to dissolve when dried quickly).

Also paint the other side of the plate.

If you don’t do this, you have a chance that it will bend

† When you have finished grounding, you wait at least 6 hours!

Then sand with grit 220 and make it dust-free again.

Now you apply a second base coat.

Roughen again and finish with a water-based paint the silk or high gloss.

You will have to ground the short sides more often because they are porous.

Another piece of advice I want to give you: use the same type of paint for both sides!
