Best sealer to use on MDF cabinets. I'm reprinting due to paint chipping. I've cleaned, and sanded cabinets smooth and need to know which sealer to use. Know enough to know not to use anything water based so MDF won't swell. I want the best so I don't have to do again in a few years. Sealer, prime, then paint. Please help me with this information. 

Thank you, Dee

Hello Dee,

Thanks for joining us here on the community.

It sounds like you've done the research and the hard part already with cleaning and sanding your MDF cabinets.

The good news is that at a primer ALSO acts as a sealer; that is one that will be effective for your cabinets.

For your situation, I would recommend an oil-based primer, since as you stated yourself, it won't seep into the MDF and cause it to warp and buckle.

One of the very best we sell is shown below and linked here.

You would apply the primer with a quality brush and/or roller. Just double check the cabinets to ensure they are clean and free of dust from the sanding before applying the primer.

Allow it to dry 1 hour minimum before using a high quality glossy paint. 

Even though this primer is oil-based, you can still top coat it with a latex-based paint.

Let us know if you have any further questions,
