- Rusted steel (ferrous) surfaces
Dy-Mark Zinc Guard RUST CONVERTER is a tannic acid based rust converter specially formulated for the treatment of rusted surfaces. In one easy step, Zinc Guard Rust Converter chemically reacts with the rust to form a black inert organic compound that binds to the surface and provides a barrier by sealing out moisture for effective rust protection. Suitable for use under most paint systems. For superior protection it is recommended to overcoat with Dy-Mark Zinc Guard Primer and then either with Dy-Mark Zinc Guard Quick Dry or Dy-Mark Zinc Guard Epoxy range of topcoat colours within 3 months of surface preparation with Zinc Guard Rust Converter. Zinc Guard Rust Converter is ideal for use on gutters, roofs, garden furniture, fencing, gates, trailers, machinery and equipment. Does not contain Phosphoric acid.
Preparation: Surface should be clean, dry and free from contaminants such as oil, grease, dirt, dust and salt. Remove all loose and heavy rust scale and flaking paint with a wire brush, scraper or mechanical sander. Rinse with water or solvent to remove loose particles. Allow to dry. 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 the can occasionally during use. Hold the can upright approximately 20-25cm from the surface. Spray with a smooth sweeping motion. To prevent paint from sagging, apply multiple coats to saturate the rust, allowing 4-5 minutes between coats. Adjust red insert on nozzle to achieve desired spray pattern. Use horizontal setting to spray up and down and the vertical setting to spray left to right. The rusted areas of the surface will turn predominantly black.
