The grit of sandpaper used to sand down painted wood depends on the condition of the paint and the desired finish. For removing old paint and smoothing out rough surfaces, start with a coarse grit such as 80 or 100. Then, move on to a finer grit such as 150 or 180 to smooth out the surface and prepare it for refinishing. If the paint is in good condition and only needs a light sanding for adhesion, a medium grit such as 120 may be sufficient. Always start with a coarser grit and work your way to a finer grit for the best results. **

Regular maintenance, such as inspecting for any signs of wear or damage and reapplying sealant as needed, can also help prolong the life of painted objects. **
