Typically, materials account for 15% of the cost charged by painters. Buying the painting supplies yourself may help you save a lot of money down the road. Be prepared to buy 2-3 gallons for painting the interior walls of an average-sized room. In addition to paints and primers 3, you will need paint brushes, rollers, face masks, rubber gloves, painter’s tape, drop cloths, sandpaper etc. While you can pick up disposable painting brushes for under a dollar from home improvement stores, reusable higher-end brushes can cost as much as $20. A standard roll of 0.98 inches painter’s tape (180 feet) will cost around $5. Equipments such as ladders or scaffolding 4 can be rented for a small cost. An interior scaffold with adjustable platform heights from 2’ to 12’ in 2” increments can be rented for around $8 per hour.
To paint a large section without leaving lap marks, roll the nearly dry roller in different directions along the dry edge, feathering out the paint as you go. After completing the entire length of the wall or ceiling, move to the next section and paint over the feathered edges. For the second coat, apply the paint in the opposite direction. This crisscrossing paint application sharply reduces (if not eliminates) lap marks.
