Whether it is a home repaint or a commercial refresh, planning the steps makes the project smoother.(Image: http://www.imageafter.com/image.php?image=b6architecture_interiors035.jpg&dl=1) Interior painters often spend significant time on prep, patch, and prime because walls and trim show imperfections under light. It also helps coordinate walls, trim and doors for a balanced look. Pressure washing before painting removes buildup and helps coatings bond more evenly. Projects for offices, retail spaces and tenant improvements can benefit from clear staging, protection for floors and furniture, and a plan for touch-ups. A simple plan and careful execution can make a space feel updated without unnecessary rework.
