You cannot apply stain, sealers, primer, paint, glue, epoxy, polyurethane, or varnish over Seal-Once. They will bead up and roll off. Also, you cannot apply Seal-Once products over stain, sealers, primer, paint, glue, epoxy, polyurethane, or varnish. Seal-Once will not penetrate leaving un-even shiny/sticky spots.
