Answers:    After you are done with the sand, put on a sanding sealer. Let dry and delicately sand again. Then use "VAR ETHANE" water groundwork polyurethane on the floor. This stuff does not yellow next to age. Put on at least two coats next to a pad. When the floors look bleak you can put on another coat with no problem.
