While a rust converter is ideal for preventing rust from recurring and making a rusted surface easier to paint, a galvanized primer is appropriate for metals (e.g. Professionals recommend two types of metal primers: the rust converters mentioned above and galvanized metal primers. ![]() To begin with, water-based (latex) primers shouldn’t be used on metal surfaces, as moisture can seep through and cause paint to fail within weeks or months. To select the right primer, the type of metal to be coated along with the desired appearance, performance requirements, and environmental conditions should be considered. Priming is a very important step in preparing metal for paint, especially if the surface will be exposed to moisture. Then, cover the mesh with epoxy, working your way from the edge toward the center of the hole. For larger holes, apply epoxy filler to the edge of the hole, cut a piece of fiberglass mesh approximately one inch larger than the hole, and press it into the filler. For small holes and dents, inject an appropriate epoxy-based composite directly into the hole and/or dent. To repair holes and dents, sand the area until you reach bare metal and wipe with a degreaser mixed with mineral spirits. Also known as rust converters, rust-inhibitive primers can be used to cover rusted spots and turn them into non-rusting, paintable surfaces. To restore lightly rusted metal surfaces to their original state, use a brush to clean off loose rust, sand the area, and apply a high-quality rust-inhibitive primer (e.g. When preparing metal for paint, checking for rust is important to make sure that the paint will adhere properly to the surface. ![]() However, one drawback of using power tools is that they can polish metal surfaces, potentially causing paint-adhesion problems. Since these methods are labor intensive and usually fail to deliver the results expected, many professionals opt for power tool cleaning, which can help remove paint quickly and easily. If the old paint is in poor condition, you can remove it by hand wire brushing, sanding, or scraping. To remove persistent dirt, wash surfaces with a mild detergent solution or with a commercial product recommended for cleaning painted surfaces. For painted surfaces that are in sound condition, remove dust with a clean, dry cloth, de-gloss the surface with light sanding, and wipe with mineral spirits to ensure good adhesion. ![]() To properly prepare new metal surfaces, use mineral spirits to remove grease and apply a rust-inhibitive primer before painting. To turn your first metal paint job into a successful experience, we invite you to check the next five steps to preparing metal for paint. Without proper preparation, even the most advanced metal coating technologies will fail. Adequate surface preparation is a vital prerequisite for ensuring the quality and longevity of metal coatings.
