Consider a few things before using an electric paint sprayer to paint a ceiling. One is the ceiling height, and another is the type of paint you're using. Latex paints are easier to use with an electric sprayer than oil-based paints. You must also decide whether or not to use a primer. An electric paint sprayer will suffice if you paint a ceiling less than 8 feet high. If your ceiling is higher, you must use a ladder or scaffolding to reach the top. Make sure the surface is clean and free of dust and dirt before applying the paint. When using latex paint, no primer is required. Simply shake the can strongly before spraying.
