Has anyone ever painted mdf sheets prior to cutting and assembling? I am charged with doing builtins in our closet. From experience, painting after assembly is a pain. But I wasn’t sure about sliding painted sheets across my tablesaw and other tools.

Cut everything to fit and get it ready for assemble then do the painting. You don’t want to be moving them around more than necessary once the finish is applied.

If you want pre-painted materials and are willing to work with mdf, ever consider melamine or pre-finished plywood as an option?

I do it with mdf moulding. Don’t see why it wouldn’t work.

Fridge does bring up a good point. Are these pieces only visible on one side or two? It’s the backside that gets scratched up when feeding sheets through a table saw. The top face stays nice and clean.

The method I used on some MDF panels for the sides of a cabinet was to cut the panels to final dimensions, then prime and paint them, and then assemble.

+1 Matt at the least prime before assembly.

I assume you are painting by brush. The problem with painting prior to cutting/assembling, is you have to wait for the paint to dry before doing anything further. Maybe priming is ok, but there will still be some drying time required.

A track saw or track jig for a standard circular saw is an option too.

If spraying is an option I would cut, assemble, and then spray.

Thanks for the replies. I decided to cut, dry fit, paint, then assemble. Been painting for 12 hours now – 17 sheets of mdf takes a while. I’ll post pics when i finish our closet.

Have your say...
