Can You Sand Grind Wood With Varnish

Mar 05, 2020 Use at least 200-grit paper. Before you can wet-sand your wood, you’ll need to apply a varnish or lacquer and leave it to cure overnight. Soak your sandpaper of choice in water overnight while your wood is curing. Then, dry-sand your wood with regular sandpaper, starting with 80-grit and working your way up to 180 or until the surface is smooth.
