Fine sanding, between coats of epoxy, coats of varnish or final sanding, before buffing is time consuming and often tedious but necessary to achieve a flawless finish. In this case, I'm sanding the final coat of epoxy before applying the 1st coat of varnish.
A question that I'm often asked is how fine do I sand the final coat of epoxy. Generally I sand to 220 grit. According to several varnish manufacturers, that is fine enough so that sanding marks will not show and coarse enough to ensure maximum bond between the epoxy and the varnish. When sanding the final coat of varnish, before buffing, I work my way up to 1200 grit with wet paper.
