Considering this, 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.
Also, can I use water based primer on MDF? 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.
One may also ask, can you use primer on MDF?
The cut edges of MDF are especially porous, so you need to pay particular attention to sealing these areas. You should always apply two to three coats of primer before you attempt to paint MDF. In between coats of primer, it is a good idea to lightly sand the surface.
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.
