Sanding, cleaning, priming and painting are the four basic steps to spray-painting furniture. Depending on the furniture material, you may need to use a specific type of primer or grade of sandpaper. An additional weatherproofing step is necessary for wood-based furniture, including reclaimed timber storage chests and chairs.Continue Reading
Use a sander or traditional sandpaper to work off surface-level paint, debris and rough edges from your furniture. Keep in mind that metal furniture requires a coarse sandpaper in order to remove rust, paint buildup and rough edges. If you are working with a wood material, then a finer sandpaper is acceptable.
After sanding, clean the furniture with warm, soapy water, using a rag and a mild detergent such as a castile soap or mild dish soap. Allow the furniture to dry, and check for any areas you may have missed.
After you are sure the furniture is clean of any debris, prime it with a suitable primer, then allow the furniture to dry. If you are painting wood furniture, use primer that offers a waterproof seal or other form of weatherproofing agent. If you are painting metal furniture, be sure the primer has some form of rust protection.
Applying the spray paint according to the manufacturer's directions, paint the furniture with your chosen color. Give the paint sufficient time to dry before using the furniture.
