Water Borne Millwork Primer is a very fast drying interior/exterior water borne pre-primed millwork primer with very good adhesion, holdout and sands easily between coats. Water Borne Millwork Primer is designed to be a production transport primer, which is only intended to seal the substrate from incidental exposure to the elements prior to applying the final finish coating system. M.L. Campbell^® can not evaluate local available paint systems. Consult a paint professional or paint manufacturer for the coatings best suited for project. Failure to finish the substrate as instructed may result in performance problems.
