Every time that I have hired someone to paint the exterior of my house in the past, they've done it the slow, hard way: with brushes. They have all been professional painters with legitimate painting businesses, and they've done very nice jobs.
This year, because I have been feeling poor, I decided to buy a fairly nice $300 paint sprayer and try painting the house myself, instead of paying the professionals $10k to do it. When I used the sprayer for the first time the other day, I was amazed at how fast it went. I did about a fifth of the house in four hours (and it's a large, 4000-square foot, double-family house).
That left me wondering why professionals would ever not use sprayers. I know that sprayers waste a fair bit of paint, and that it can be harder to get an even finish when you're spraying. But the wasted paint seems worth it if you can do ten jobs in the time it would take to do one by brushing. And I assume that professionals would learn how to spray paint evenly.
I know some professionals use sprayers. But the guys I have hired don't, and again, they were very good, professional painters.
So can anyone enlighten me as to why you would not use a sprayer if it was your job to paint houses, and the amount of money you could make with a sprayer is much higher?
