Plywood edges dusty and “washed out” after sanding
Hello. I am making a floating box-style wall shelf out of 3/4″ baltic birch plywood with exposed edges and have run into a sanding question. After sanding the first piece, I realized that the edge becomes noticeably dustier, lighter tone and looks kind of “washed out”. The problem seems to be that the end grain plies really absorb the dust. I vacuumed the edges and cleaned with a damp cloth which helped somewhat but not enough and it also made the surface rougher again. For me the appeal of plywood is the crisp contrast between the light and dark plies rather than a monolithic cloudy look so I’m curious how others deal with finishing exposed plywood edges. Any tips much appreciated.
