How to get EPS foam smooth without spackle? Screen or sandpaper?
We screen EPS with 100 / 150 / 220 / then 320 grit for a super smooth, spackle-free surface. Each screen grit cuts the beads until all the small voids between beads are gone. We use a foam sanding pad with the screen to even out contours. It's more work than spackling but leaves a very nice and clean foam surface.
