Moisture can also damage the core particleboard, causing swelling.
For oil-based paints, use an oil or latex bonding primer.
For water-based paints, use a water-based primer.

Apply Primer
After sanding the item, apply the primer to the surfaces.
Allow theprimerto dry completely (usually 24 hours) before applying any paint.
Lightly Sand the Surfaces
Before applying paint, lightly sand the primer layer.
This will ensure that the top coat goes on smoothly and sticks well.
After sanding, remove any dust with a lint-free rag.
(However, if you like the texture created by brush strokes, use a paintbrush.)
Depending on the paint, one coat may cover the surfaces adequately.
If you need a subsequent coat, let the first coat dry completely before applying the next one.
A very light sanding between coats will help with adhesion.
Tip
Whenchoosing paintfor furniture, a gloss or high-gloss finish is usually best.
Gloss paints resist marking and are easier to scrub clean, which is especially important with furniture.
Avoid painting particleboard without sanding it first.

Sanding also helps to smooth the surface for a more polished look.
A quality primer will help seal the particleboard before painting it.
