The problem with painting along the edge of textured ceilings is that it's almost impossible to get a straight line along the top of the wall without getting paint on the ceiling bumps. Pros have a simple solution. They run a screwdriver along the perimeter of the ceiling to scrape off the texture. “This lets you cut in without getting paint on the ceiling texture,” one of our pros says. “The screwdriver creates a tiny ridge in the ceiling, so the tips of your paint bristles naturally go into it. And you'll never even notice the missing texture.”
