Spraying exterior wall surfaces on most homes and businesses is the preferred method for paint application.  However, a lot of the trim surfaces will have to be brushed.

Spraying textured surfaces is also the preferred method as it delivered a more consistent, even look.  Popcorn textured ceiling is an example for interior painting.  Exterior stucco surfaces is another example where we typically would spray and back roll with a roller to deliver the most consistent results.
