The amount of wood removed during sanding depends on the grit size and the type of sanding equipment used. For example, using a three-head sander with a grit sequence like 100–150–180 typically removes about 1/32 of an inch in a single pass. Coarser grits will remove more material, while finer grits are used for smoothing. It's important to choose the right sequence to balance material removal with surface quality, especially when working on floors with limited wear layers.
