You can’t cover large areas like ceilings, extra-tall walls or stairwells in single, continuous strokes, so the best way to minimize lap marks on these areas is to feather out the paint along the edges that you can’t keep wet. The thinner, feathered coat of paint will avoid the buildup that causes the lap mark. Pro tip: alway use and extension pole. I own about 30 of them.
