Repainting MDF Cabinets: When It's Worth It and When It Isn't

"Should we repaint the old MDF cabinets or replace them entirely?" is a question most clients ask once they hear the price of new cabinets. The answer depends on two things: the condition of the MDF core under the paint, and what you actually expect from the end result.

When repainting is genuinely worth it

If the MDF core of the doors is sound — not swollen, not softened by sink moisture — and only the paint on top has faded or scratched, repainting is usually the best option. The cost is a fraction of new cabinets, and if done properly (full sanding, the right primer, quality polyurethane or oven-baked paint), the result can last for years.

• Framed solid-wood doors get the best results from repainting, since their surface holds paint well.
• Membrane or PVC-foil doors usually take paint poorly; paint doesn't bond to PVC foil the way it does to raw wood, a difference we covered in membrane vs high-gloss cabinets.
• If you only want a color change with no damage to fix, stickers or refacing covers are also a faster option — see the comparison in cabinet refacing vs sticker covers.

When repainting is just throwing money away

If the MDF core under the paint is swollen, softened, or delaminating — usually near the sink and under the faucet — fresh paint only hides the damage for a few months, not longer. Paint over an uneven surface also cracks quickly, and the final result won't look professional. In that case, replacing just the damaged door (not the whole cabinet) is usually more sensible than repainting.

Paint improves a good surface; on a damaged one, it only delays the problem by a few months.

The right steps for repainting

Repainting without proper prep always peels early. The correct order is: fully sand the surface to remove the old paint and its sheen, apply a primer made for MDF so the new paint sits on an even surface, and finally apply polyurethane or oven-baked paint in two thin coats instead of one thick one — a single thick coat cracks sooner.

• Full sanding of the surface, not just wiping off dust.
• A primer made for MDF, not a generic wall primer.
• Two thin coats of paint instead of one thick coat.

What to check before deciding

Before choosing between paint and replacement, look closely at the edges and undersides of the doors, not just the front surface. If only one batch of doors has a problem while the rest are sound, you can repaint just those and keep costs down — the whole cabinet doesn't need to be replaced at once.
