Red oxide primer is an anti-corrosion undercoat designed to stop rust formation. It can be applied directly over a rusty surface after sanding and cleaning the surface and is most ideal for exterior and interior use. Red oxide primer can be covered with most conventional topcoats once it fully dries. The application usually happens with a brush. But in order to reach out to the small non- brushable areas, conventionally Indian Applicators use an old cloth dipped in the primer paint to ensure 100% coverage and also to reduce base paint consumption. It is popularly believed that brush coats allow dripping thus leading to acute wastage. Red oxide primer is a specially formulated coating used as a base coat for ferrous metals. Red-oxide primer serves a similar purpose to interior wall primers in that it prepares your metal for a topcoat, but it also gives iron and steel surface a layer of protection. Working with red oxide primer is not difficult, but it helps to be aware of some safety precautions and application tips.
Uses
Red oxide primer is intended for use on interior and exterior ferrous metal and is not usually suitable for galvanized or nonferrous metals like aluminium, copper or brass. Ferrous refers to metals that contain iron. If you’re uncertain whether your metal is ferrous or nonferrous, use a magnet to test it. Ferrous metals are magnetic, and nonferrous metals are not. It is also not suitable for use on asphalt or bituminous surfaces.

Surface Preparation
Before painting with red oxide primer, make sure all substrates are clean and free from dust smog grease old residual paint flakes or oil. Use a degreasing solution to remove these materials and allow the surface to dry. A clean surface ensures that the paint applied after the primer adheres properly. After cleaning, remove all loose and flaking material by scraping with a paint scraper, wire brush or by sanding. For some metals, flame cleaning or grit blasting may be necessary.
Application and Drying Time
When applying red oxide primer, use a brush or a short pile roller. As mentioned earlier, soft cloth is also a good idea. Thinning is not normally required if applying with a brush or roller. If you use an airless sprayer to apply red oxide primer, thin the primer 10 to 15 per cent by volume with acetone, xylene or synthetic reducer. In Indian conditions, Applicators use mineral Turpentine oil. Begin thinning with as little solvent as possible and add more as needed until you achieve the right consistency. Use at least two coats of red oxide primer to provide the right and ready surface an adequate base coat to your metal. Each coat will be dry to the touch in about 2 hours, but not fully cured for about 6 hours. Now, these are approximations. The actual drying time may vary due to atmospheric humidity conditions. Red oxide primer will not be ready for an overcoat until it dries for between 16 and 24 hours. Always check the manufacturer’s label for specific instructions on drying times.

Precautions
Red oxide primer, like other paints and coatings, should be used with standards and safe working practices in mind to avoid injury or hazards while handling. Red oxide primer is flammable, so keep it away from sources of ignition such as open flames and cigarettes. Before you begin working, ensure you have adequate ventilation. Either work outdoors or open all windows in your workspace and make use of exhaust fans. Wear a respirator or a painter’s mask to avoid breathing in vapours and spray. Safety goggles, gloves and protective clothing should also be worn. When you’re through painting, do not discard unused paint down drains or other watercourses. Dispose of in ascertained garbage bins only.
