I just had the final coat of polyurethane put down on my new hardwood floors, and about five hours after my two year old rips back the plastic that was covering the door way and runs barefoot across the floor and back. Now there are little foot prints going across the floor. Is there anything I can do to get these out. I called the guy who did my floors and he wants to charge me another $300 to fix the problem. If there is anyone who knows of something that I can do I would really appreciate the help.
I would just to to any hardware or paint store that generally caters more to the furniture makers and cabinet builders in your area and buy some "Wiping Polyurethane". This is an alkyd based polyurethane that uses very small resins and has been thinned more than regular polyurethanes are so that it's not nearly as viscous as regular polyurethane "varnish". It's about the consistancy of cream maybe.
Then, just DAMPEN a small WHITE rag with the wiping polyurethane, and wipe down those foot prints with the poly. Keep the poly rag in a CLEAR plastic bag with as much air squeezed out of it as possible between coats so the poly doesn't harden up. It's shouldn't take more than 3 or 4 quick wipes to restore the surface to it's original gloss.
Always use a white rag and a plastic bag with no ink on it because the solvents in the poly might dissolve the dye or ink on the bag, giving you a coloured polyurethane, which you don't want. You can usually use acetone to remove ink from plastic bags. Or, use a freezer bag, maybe.
Most likely, it's simply the surface of the poly that was roughened by the footprints, and all you need to do is smooth that surface.
