- 1). Start by thoroughly cleaning the floor area all around the stain with denatured alcohol.
- 2). Using 150-grit sandpaper and your orbital sander, sand away the top layer of the stained wood. (The water will actually have gone right into the wood so you need to get rid of all the gray color.)
- 3). Move the sander gently around on the floor and let the sandpaper do the work. You don't want to press too hard or you could create sanding marks on the wood.
- 4). Soak a lint-free cloth with mineral spirits and use it to wipe up all the dust on the floor.
- 5). Using your natural bristle paint brush apply the polyurethane finish. Start at one side of the sanded patch and spread the poly in one direction only.
- 6). Allow this first coat of poly to dry thoroughly (overnight is best) and lightly touch up the finish by hand with the 220-grit sandpaper.
- 7). Wipe up any dust and apply a second coat of poly, then allow it to dry thoroughly before walking on the floor.
