Magnalac^® Primer/Undercoater is a fast dry, easy sanding performance nitrocellulose lacquer primer/undercoater. It is specially formulated for use as the first coat under Magnalac^® Pre-Catalyzed Pigmented Lacquer but will also work as an excellent primer/undercoater for other products. It exhibits very good adhesion on wood, particle board and hard boards. Also, has good holdout over porous surfaces such as soft wood and untempered hard board. Sands very well to produce an excellent base coat with outstanding holdout of topcoats.
