Fill any scratches on the face of the MDF with drywall compound as well, as any mars or scratches will be painfully obvious once painted. Sand the entire piece with 220-grit sandpaper, then wipe it all down with tack cloth to remove fine dust and any remaining dirt or debris. Priming and Painting MDF doors should not be primed with a water-based product. Paint MDF cabinet doors with at least two coats of quality paint, whether you choose to use water-, lacquer- or oil-based products. Allow all of the doors to fully dry before you reattach the doors and hardware. Seal MDF Edges Which Are the Most Absorbent The edges of MDF boards absorb paint heavily. Make sure to seal these, especially if they have routed details. You can use an acrylic paint sealer or drywall sealer, or you can use glue or oil based primers which will help prevent the edges from swelling. You should always apply two to three coats of primer before you attempt to paint MDF. For the best results, you can lightly sand the MDF between coats of primer. Allow at least an hour before you start painting, otherwise, the primer may not be totally dry. It's a good idea to prime both sides of a piece of MDF. You can make cabinet doors out of MDF even if the cabinets are made of plywood, wood or some other material. MDF always has to be painted, but you can choose a color that blends with the cabinet material, even if it is stained or unstained wood. The simplest design consists of flat panels.

You can use a variety of paints or stains; the trick is to seal the MDF first, then build up layers of paint or stain. Both paint and stain can be finished with a gloss coat to make the MDF look like high-end wood.

Cabinets made from MDF are often coated with a thermofoil coating. Thermofoil resembles paint, but is more resistant to stains. Refinishing MDF cabinets cannot be done in the traditional sense because you cannot sand away the original finish and apply a coat of stain. However, you can paint MDF with good results.

Painting MDF – Key Points Seal the edges of the board with extra layers of primer or optionally with putty. Paint the back of the board to prevent moisture ingress. Acrylic paints are the best primers and undercoats; Blackfriars is a great option.

Painting MDF or Medium Density Fibreboard is not an easy job. The paint dries so quickly that it can dry in a very uneven and blotchy way. Special primers, such as the one below, are available for MDF and once applied the timber can then be painted with any ordinary paint.

Is MDF really that bad for you? Let me start off by saying yes, you should avoid breathing MDF dust. Formaldehyde is suspected of being a carcinogen, and MDF has some of the highest concentration of urea-formaldehyde adhesives out of all the engineered wood products that use it.

You can also create waterproof MDF by adding a high quality wood sealant, varnish or stain or moisture-resistant paint so that your project can withstand threats of moisture and humidity. Do not use waterborne polyurethane, as it may not bind readily to the MDF's surface.

MDF easily absorbs water, and water-based paints and primers make the wood fibers swell. You can sand the fibers down, but sanding may not fully repair the damage. This is not an issue with non-water-based primers. Two coats of primer are best, particularly for the cut edges of the wood.
