Sanding doors with an orbital sander is an effective and efficient method for refinishing or preparing doors for painting. Orbital sanders, particularly random orbit sanders, are well-suited for this task due to their ability to produce a smooth, swirl-free finish. They can handle various door materials, including wood, and are capable of removing old finishes, smoothing surfaces, and preparing doors for new coats of paint or varnish.
