Just like any other metal, brass sheet metal can be painted for decorating purposes. Paint can be applied to sheet metal used for cabinets, frames, wall art, backsplashes, and message boards among other structures. However, painting brass sheet metal requires particular techniques.
Paint will only adhere to the metal if the surface is rough. So, before painting, analyze the metal's surface first. If smooth, roughen it up by using steel wool or high-grit sandpaper. Make sure that the texture is light and even, void of deep grooves.
Because dust and dirt may prevent paint from sticking to sheet metal, you need to also clean the sheet. Spray white vinegar to the surface and use a clean rag to wipe it down. The vinegar's acidity will render an abrasiveness to the metal sheet. After cleaning it, spray the metal with compressed air to remove remaining dust and dirt.
Also known as an undercoat, a primer is a substance that helps the paint better adhere to a surface. You can use either an oil-based or a rust-resistant latex primer to protect the coating from corrosion and prevent the paint from peeling.
Choose a paint that is exclusively made for metal, one that resists rust and lasts longer than normal wall paints. Apply two coats of paint. However, wait for the first layer to dry completely before applying the second one.
Following these steps will result in a proper paint job that leaves an attractive finish on the metal.
