Vinyl wrap on mdf

RandyT:


You do not want a coarse surface for PSA backed material.  Think of a surface as a microscopic mountainscape.  The coarser the surface, the greater the difference between peaks and valleys.  The greater this difference, the less adhesion you will have, as the adhesive will only be sticking to the peaks or whatever portion in can conform to.  The smooth, unsanded surface of the MDF would actually be better than a coarse sanding.

Seal it, fine sand until smooth, wipe down well with a tack cloth and apply the vinyl.

Thanks for the advice 👍
I'm going to prime it, sand it, and then decide. Either way, i'll post pics when it's done.

Randy's analogy is solid, I hadn't thought of it that way. A smooth surface would reduce the number of possible bubbles as well it seems. Sorry to give bad advice...although my main advice is vinyl wrapping an entire cabinet kinda sucks!
