Styrofoam Sealing Before Painting

Enzo729

Hello all, I have some acoustic panels (just for the looks) which I would like to paint. The foam however is extremely porous and I need a good way to seal it so paint can be applied. What can I do to accomplish this?

idye poly or Rit dye works for most plastics. Never seen it used on an open cell foam before, but can't imagine why it wouldn't work.

You can mix them for more specific colors too.

You'll probably want to soak it in like you would water in a sponge, then squeeze it out. Test on a small piece first. Also it's a pretty messy process that involves heating up a bit pot of the stuff, so you'll probably want to do it outside if you have a portable burner.
