When it comes to painting a room, a spray gun will most definitely get the job done quicker. However, using a spray gun to paint walls is not as simple as it may seem. You may be saving time by skipping the tediousness of a paint roller or brush, but you're opening the door to a whole new painting method...and inevitably, a few new painting mistakes you'll want to avoid.
Spray guns tend to apply paint in a thinner, more airbrushed layer, meaning this technique won't hide imperfections on the wall as easily. Plus, if you have some experience with similar paint applications, like spray paint, you'll know that if you spray too closely, your surface area can end up with a blotchy finish.
