The right paint stroke to use in interior painting is highly debatable. It's not a talent as much as a skill that is learned through practice. Many experts paint in a “W” pattern when using foam rollers, but others simply roll up and down then sideways with either brushes or rollers. The motion isn’t as important as making sure that the application is even and drip-free across the entire area. However, technique is important when you're covering over wall repairs.
A fellow (actually lives in the same neighborhood) by the name of Wayne Hickey (843-655-0366) painted the ceilings and most of the walls of our house in February 2017. He got paint all over my light fixtures, all over my trim around the doors, and had visible lap marks everywhere on the walls. He came back and rectified some of the problems, but not all, as I have noticed as I have had time to look more carefully at the work he and his assistant did. His assistant had no idea (not a clue) how to roll paint on a wall or ceiling. Some places were not covered. He said he would pull nails for pictures and then re-insert the nails exactly where they were. This he did not do as he promised. He painted over the nails. His assistant had no idea how to use a paint roller. I have painted all my life, and would have done this work myself, but I just had a full knee replacement and the other knee is in bad shape. I just could not do the work. Wayne is a pleasant and congenial individual, but he can not cut in a ceiling or wall to my satisfaction - not even close. He should have a putty knife and wet cloth with him all the time to correct any paint that might get applied where it shouldn't. That is something I always did as a painter. I would not recommend Wayne to paint anybody's home.
Purchase surety bonds. Surety bonds essentially act as a kind of agreement between the contractor and the person hiring them that the job will be performed to standard. You can obtain these through your current insurer as a separate form of financial protection. As a contractor, many states require you to be bonded before you can begin working legally.
The perfect roller would hold a roomful of paint, leave the right amount of texture, wouldn't spray or fuzz, and would be easy to clean. Until somebody invents the ideal one, follow these tips to choose the right roller. "The longer the nap, the more paint the roller will hold, but it will also create more texture." says Dixon. "A 1/2-inch nap lamb's-wool roller holds plenty of paint without too much texture," says Dixon. "Less expensive rollers can work," says Span. "Just wash them first in dishwashing liquid to remove any stray fibers." Most of the pros we spoke with prefer 9-inch rollers over 18-inch models -- they are lighter, cheaper, and easier to use. Despite these shortcomings, Maceyunas swears by the wider roller. "The roller can do a whole wall in a few up and down strokes instead of in several dozen W and M strokes," he says.
