I had new hardwood floors installed and decided on a water based poly because the is no color and I wanted a more natural looking floor. I have several spots on the floor already and I have had five people ask me if my floors were LAMINATE!! Ugghhh-really. Can you go over the water based poly with an oil base poly with sanding the entire floors? My installer was the one that recommended the satin finish-does water based poly come in a higher gloss? My floors look laminate because they basically have no shine-HELP!!
