OF the different type of customers there are at least two: cheap charley's and people who want great results. I agree the need for wall repair is critical to the end results. Most critical is for the customer to be told ahead that the walls are going to need exactly what is needed. This means the contractor must look, touch, examine the walls for defects and needed work. I've been a building manager for 40 years and seen a few paint jobs. Typically a contractor does a lot of talking about how expert he is, but the guys who walk through with note pads, iPads, examine, measure, point things out, explain and recommend are the ones I will deal with. It confirms if they know what the business. Nobody likes the workers to show up and when you talk about the job they're going to do they know nothing but they we were told to be here. Their boss who bid the job doesn't supervise - a big no no around here. Nobody likes surprises or worse, at the end of a job that's not right getting a bunch of little kid excuses. Contractors that do not like the customer to be around looking at the progress don't get the job.
Remember: You want to get the highest quality paint your budget will allow to ensure its lasting beauty. You'll also need painting supplies like primer, brushes, rollers and painter's tape. A professional will have these items on-hand. According to statistics, paint and other supplies account for about 15 percent of a professional painter's total cost; labor will factor into 85 percent of their charges.
Lap marks are those ugly stripes caused by uneven layers of paint buildup. They occur when you roll over paint that’s already partly dry. (In warm, dry conditions, latex paint can begin to stiffen in less than a minute!) The key to avoiding lap marks when doing DIY wall painting is to maintain a “wet edge,” so each stroke of your roller overlaps the previous stroke before the paint can begin to dry.
I used to work at Sherwin Williams. The best thing to do is specify that you will purchase your own paint. If the painter objects strenuously, he was plaanning on making money in the ways this article outlines. You might pay a few dollars more for paint, but you will have control of the quality of what goes on your walls. Never skimp on paint quality.
