The expression 'you get what you pay for' can be applied to nearly every profession. Of course you need to hire the painter that suits your budget however, the cheapest painting estimate may not include everything and you may end up paying more in the end. Painters usually bid their projects based on an hourly rate and they need to account for prep time, supplies, type of paint, ceiling height, difficult access points, and number of people working. When receiving a price estimate, ask the painter to break down the cost as specifically as possible so you understand where your money is going and ask about any required deposits or schedule of payments. Ask the painter to talk through potential unexpected costs that may throw off your budget. It's best to clarify all projected costs in the beginning before the work begins.
If you paint over dirty, oily surfaces, the paint will easily chip or peel off. So before painting, clean grimy areas with a deglosser or heavy-duty cleaner intended for prepaint cleaning. They work well to clean painted, varnished or enameled surfaces to improve the adhesion of the new paint. They’re ideal for cleaning greasy or oily areas like kitchen and bathroom walls and removing hand marks around light switches and doorknobs.
Concrete walls must always be prepared before painting, but in some cases previous finishes will also have to be removed so that paint doesn't peel or chip off. Additionally, special sealants, primers and paints may be applied to ensure concrete's endurance in face of the specific elements. Depending on the wall's condition and exposure to the sun, painting professionals will usually estimate between $500 (~250 sq. ft.) and $2,000 (~1,000 sq. ft.), depending on wall area to cover.
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.
