Besides being faster, are there any other benefits from spray painting a wall rather than using a roller?

which one is better or are they the same? Besides being faster, are there any other benefits from spray painting a wall rather than using a roller?
A friend of mine (top professional) sprays interior walls. He says it is not quicker because you have to mask everything up. Also, it takes awhile to learn how to get the pressure just right on the equipment.





The benefit is the finish, but not speed.Besides being faster, are there any other benefits from spray painting a wall rather than using a roller?
When pros spray-paint a wall, they generally 'backroll' it afterwards. The texture from rolling is much better.
I never spray paint interior walls, ever. It gets paint all over the ceiling, you have to seal the floor and furniture in dropcloths, and you have to wear breathing protection and eye protection and cover yourself completely from head to toe (while it's warm enough to paint - boiling hot is how it feels). Then you have to use specific paints to suit the sprayer which may not have the qualities you want in a paint. It's often cheaper to roll on a top-grade paint that looks rich and lasts ten to fifteen years than to spray on a cheap paint with chalky colour that looks old and dingy in three years.





And yes, it's marginally quicker to paint with a sprayer, but I find that 75% of the job is in prep - cleaning and repairing the walls, taping the trim, and cutting in: the actual painting takes less than an hour of actual work per room. Why worry about making that tiny part of the job faster, especially given there are so many disadvantages to spraying?





Exterior walls have some of the same concerns. Where I live, cheap paint doesn't last more than one year, and most sprayers are only guaranteed to work if you use the company's regular brand (usually cheapish at least). And although you don't have to worry as much about obsessively protecting every inch of the floor from spray, you do have to protect things like flowerbeds and stone foundations.





Where sprayers really save money is with respect to things like garages and fences, where you don't really have much prep, and especially barns and outbuildings.
