Thank you for sharing your experience using our Varathane Water-Based Floor Finish Polyurethane. You may wish to consider switching over to a coat of satin finish polyurethane, since this will not show surface imperfections as readily. Gloss finishes are the hardest, most scratch-resistant polyurethane finishes, however, they will show smudges and scratches due to the amount of light reflected. While tiny scratches in the finish are likely superficial, the thickness of the polyurethane will provide its scratch-resistance, so building up the thickness of the poly may be necessary if the floor is scratching to easily in your opinion. If you can give us a call at 800-901-0411, we will be happy to look into the amount of polyurethane used for the six coats applied, and help find a solution for your floor. - Rust-Oleum Product Support 2
