GENERAL INFORMATION

Zinc Coat Barnacle Barrier 1792 provides easy to use aerosol spray protection for bare metals including steel, stainless steel, cast iron, copper, bronze, galvanized steel, and lead. It forms an excellent bond to underwater metals and running gear, and inhibits corrosion on these surfaces. The smooth, hard surface of the Zinc Coat Barnacle Barrier will self-clean in service, and can be used above or below the waterline. The dried film of Zinc Coat contains 93% pure zinc. Not for use on aluminum surfaces.

APPLICATION INFORMATION

Shake can vigorously for two minutes after mixing balls begin to rattle. Shake often during use. Hold can upright 12 to 16 inches from the surface and spray in a steady back-and-forth motion, slightly overlapping each stroke. Keep the can the same distance from the surface and in motion while spraying. Applying in thin coats. Allow no more than 5 minutes between two or three thin coats, otherwise allow to dry one hour before applying additional coats.

When finished spraying, clear spray valve by turning can upside down and spraying until no more paint comes out. If valve clogs, twist and pull off spray tip and rinse it in a solvent such as mineral spirits. Do not stick a pin or other object in the stem.

SURFACE PREPARATION

Remove all paint from underwater metals and running gear by sanding, scraping, sandblasting or by using a paint and varnish remover. Once back to bare, clean metal wipe the surface with Pettit 120 Brushing Thinner and let dry. For application to metals above the waterline remove all paint and rust with a wire brush or sandpaper. Lightly sand glossy surfaces. Clean surface with Pettit 120 Brushing Thinner and let dry.
