Spray painting wood is a simple way to customize a piece of furniture or art. Wood is naturally porous, so it is necessary to apply a coat of primer before spray painting to prevent the wood from absorbing all the paint. The primer will also make the color bolder. Sanding the wood beforehand ensures an even application of the spray paint, and gives the primer a better hold on the wood surface.
Fill a bowl with warm water and add 2 tbsp. of liquid dishwashing detergent. Dip a clean rag in the soapy water and wipe down the surface of the wood to remove any dust or grime. Rinse the cloth and wipe the wood again to remove the soap residue. Let the wood air dry for 24 hours.
Sand the surface of the wood with a fine grain sandpaper. Follow the grain of the wood while sanding. This will remove any existing varnishes or potential splinters. Stop sanding when the surface feels smooth.
Wipe the wood with tack cloth to remove dust from sanding.
Shake a can of spray-on primer for two minutes. Hold the can 12 inches from the surface of the wood and begin spraying on the primer in a back-and-forth motion. Overlap each pass by one-third. Continue until you cover then entire surface of the wood. Let the primer dry according to the package directions.
