Changing a stain color is a standard part of a full-sand refinishing job. After the existing finish and old stain are removed by sanding down to bare wood, the floor must be prepared for the new application. Be aware that the final color is determined by the species of wood, its natural undertones, and the condition of the wood fibers. A wood conditioner may be necessary for softer woods to ensure even absorption. Always perform a patch test on a sample board to verify the final color before staining the entire room.
