Sanding a wood floor is a messy but rewarding job that brings out the natural beauty of the grain. You start with a coarse grit to remove old finish and scratches, then work your way down to finer paper for a smooth, even surface. It takes patience and a good respirator, but when you finally wipe away the dust and apply the first coat of oil or polyurethane, the warm glow makes it all worthwhile.
