When refinishing a bathtub, it’s essential to use the best sander for the job. A random orbital sander is the ideal choice, as it can quickly and evenly remove old paint or varnish without damaging the surface of the tub. When choosing a random orbital sander, look for one with a variable speed setting, as this will allow you to adjust the speed of the sander to match the hardness of the surface you’re working on.
It is also important to use the correct sandpaper grit. For removing old paint or varnish, start with a coarse grit sandpaper, such as 60-grit or 80-grit. Once you’ve removed the old finish, you can switch to a finer grit sandpaper, such as 120-grit or 150-grit, to smooth the surface of the tub.
