I have new 4 inch oak floors with a M***** Dark Walnut finish. I have several issues that I an concerned about. For one, there are a number of areas that have tiny sand mark circles. Lots and lots of them. The flooring company said there is just no way around that with a dark walnut stain. Also, there are many areas that have a variance in the color, for instance, boards that are much lighter in color or much darker. Finally, there are areas where there are stripes, like tiger stripes. Is this true that this is the absolute best that can be done? I want to be fair to my contractor and not have unreasonable expectations, yet I also want to be a good consumer and be treated honestly and fairly. Any insight would be helpful.
