Painters spend two to four days painting a medium-sized room. That's how long it takes to prepare, prime and paint properly. It's more work, but if you stay behind to admire the results, you'll agree that it's time well spent. One advantage of professional painters is that they tend to work faster than you.
They have a team, while you may only have a partner or a positive attitude to ask for help. Even so, a professional painting team spends two to four days (between 8 and 16 hours) in a 10-foot x 10-foot room because preparing, priming and painting is a time-consuming process. Before hiring a professional painter, they should be able to estimate how long the job will last. House painters cost a reasonable amount because quality paint protects your home and can even increase the value of the property.
