What sort of finish is on the pre-finished flooring?
We use a 7 coat, UV cured, solvent based polyurethane with Aluminum Oxide added to coats 4&5. It is “clear” or “natural” and no stain is used or available. This is a very durable “satin” finish that should perform well for at least 15 years before a slight scuff and recoat might help freshen it up a bit.
