Before we purchased our home, it had a water leak that bowed the hardwood floor near the fridge. The previous owner fixed the leak and a contractor half-assed fixed the floor. The color is pretty good but it is very dull. Do hardwoods typically need some sort of poly or clear finish? Can I just apply this to the section I need in hopes of blending it? I don't want to refinish an entire floor (it's a lot of sq footage) and we have dogs and a child, it'll only get beat up at some point. We just want it to be better. Any suggestions? I'll see if I can't get a picture but it may be hard to get it to show up. Thanks.
