It really depends on the job you are doing. Airless paint sprayers are excellent at producing good quality uniform paint. They can also help you achieve textures and popcorn effects. Finally, if you are painting a large area, they are much, much, quicker than using a roller or a brush. Compared to other forms of paint sprayers, they have less overspray and a more uniform finish. The downside really is the setup time, cleaning, and maintenance. If you’re only doing a small job, it’s probably not worth the setup required to run an airless paint sprayer. And after you’re done with the job, they require extensive cleaning.
