There is no need to sand if the surface of the desk is already dull.
If your desk is made of unfinished, weathered, varnished wood or wood that bleeds tannins, such as cedar, you should opt for an oil-based primer. [10] X Research source Use a latex-based primer if you are painting pine, brick, or concrete. [11] X Research source Try a pigmented shellac primer for dealing with water, tannin, or smoke stains.

Unless the wood is unfinished or damaged, you should only need one coat of primer. If the wood has stains or has never been primed you should opt for two coats. [14] X Research source
Be sure you wipe the desk down following the second sand. Use tack cloth for the best results. [15] X Research source
The foam roller will save you time and prevent brush strokes from being visible. [17] X Research source
You should be between 10–12 inches (25–30 cm) from your target. The closer you move to the desk, the thicker the paint will be and the harder to keep even. [20] X Research source Keep the nozzle of the paint sprayer perpendicular to the surface you are painting. If you arc the gun, then it will cause the paint to layer unevenly. [21] X Research source Remember to paint in thin coats. The thicker the coat, the more prone to a rough finish. 2-3 coats of paint will be appropriate for most desks. If you are trying to achieve an antique look, then rub the painted edges with a bit of sandpaper. [22] X Research source
If you choose to cure, be sure the desk remains completely contact-free for the 30-day dry period, otherwise the process will not work. [23] X Research source
