Dy-Mark Zinc Guard™ Black Zinc is a fast drying epoxy based black zinc coating which provides excellent adhesion, corrosion resistance and long lasting durability to metal surfaces. It can be used as an anti-corrosive primer and top coat in a one-step application. It can also be used as a touch up coating for welded areas on galvanised products, however for longer term protection and highly corrosive conditions Dy-Mark Zinc Guard™ Cold Galvanising Coating primer is recommended before the application of Dy-Mark Zinc Guard™ Black Zinc as a finish coat.
Preparation: Surface should be clean, dry and free from contaminants such as rust, oil, grease, dirt and salt. Welds should be ground back to clean white metal. Thoroughly sand new metal and lightly sand previously painted surfaces to ensure maximum adhesion. Remove loose rust and flaking paint with a wire brush, scraper or mechanical sander. For best results, always remove rust back to bare metal. For superior protection and adhesion on mild steel surfaces and welds it is recommended to prime with Dy-Mark Zinc Guard™ Cold Galvanising Coating and allowing it to dry for 4-6 hours before applying 2 coats of Dy-Mark Zinc Guard™ Black Zinc. For non-ferrous metals such as aluminium, alloys, ZINCALUME® and stainless steel use Dy-Mark Zinc Guard™ Etch Primer.
Application: Before spraying, cover surrounding areas to protect from overspray. Shake can for at least 45 seconds AFTER the mixing ball begins to rattle. Shake can occasionally during use. Hold can upright approximately 20-25cm from the surface. Spray with a smooth sweeping motion. To prevent paint from sagging, apply several light mist coats rather than one heavy coat. Adjust nozzle to achieve desired spray pattern. Use horizontal setting to spray up and down and the vertical setting to spray across.
