Paint sprayers are not difficult to use, but they do require some practice. The overall usage, cleaning, and maintaining can be learned very quickly (within a few uses), however, it does take time to really hone in on the skill to be able to spray as quickly as professionals. Most of the skill required comes down to perfecting your hand movements, being able to move at a steady pace and squeeze the trigger just at the right time is where the magic happens. Again, it’s not difficult but you will certainly notice you get a lot better at it after a few walls.
