Using the right backer material is key—thin plywood or fiberboard works well for most DIY projects. Make sure it’s slightly larger than the area you’re covering so you can cut it to fit and overlap edges neatly. Once you’ve applied the backer, sand it smooth and prime it before attaching the crown molding. It’s a straightforward way to ensure your final project looks polished and professional.
