This outlines one experienced painter’s method for spraying self-storage roll-up doors. There are many ways to do the job, but this is a solid approach—especially for skilled painters who haven’t worked extensively on corrugated roll-up doors with silicone-modified polyester (SMP) or Kynar coil-coated surfaces, which are notoriously difficult to paint. The technique helps avoid many common problems and is efficient. It’s worth reviewing whether you’re just getting started or already seasoned; even experienced painters may pick up a tip or two. This method works well with three or four doors at a time. Start by applying a tack coat, working up the door and focusing on the bottom of each rib. By the time you reach the third or fourth door—whichever point allows the first door to tack up (tacky to the touch but no paint smears on your fingers)—you return to the first door and begin a top-down pass, focusing on the top of each rib. When executed properly, this approach ensures the top, bottom, and face of each rib are fully painted. It’s a fast, efficient method that reduces the risk of under- or over-painted areas, drips and sags, and excessive passes or angle changes just to cover the face.
