What is a good primer for MDF?

Prime the MDF with a solvent-based primer, such as Zinsser (buy online) or KILZ (buy online). Avoid water-based primer, as it may cause the wood fibers to swell, resulting in a surface that appears to have a raised grain (no matter how much effort you put into sanding).

Similarly, you may ask, what primer should you use on MDF?

Using a Paint Primer For MDF: Primers used for MDF should be solvent rather than water-based. (lacquer or enamel, rather than acrylic). Stain covering primers (Zisser makes one in a spray can) have a heavier body and can be used for the edges as well as flat and detailed surfaces.

Similarly, what paint can I use on MDF board? Painting MDF – Key Points

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

Similarly, can I paint MDF without primer?

You can manage without (of course), but you'll use more paint without priming it, and to get a decent finish you'll use a _lot_ more paint. As always with MDF, avoid anything water-based until there's a good seal on the surface - otherwise you raise fibres like crazy.

Do I need to prime MDF before painting?

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.
