My parents have a laminate countertop in their kitchen. It is rough underneath the lip that hangs over; it appears to be presswood. Apparently, it has become more rough over the years for whatever reason. My mom says if she leans against it while washing dishes, it may snag her clothing. I thought about applying a piece of laminate underneath, but it is rough and I assume it wouldn't stick well, and I don't think sanding would be real good in that position. Would a couple coats of latex paint over this make it smooth and solve the problem?
