I have recently put down a red oak floor over the concrete slab of my garage/workshop.  Because I live in Houston and we are experiencing our version of the monsoon season, I will need to finish the floor in two stages keeping my eqipment/tools in the other side not being worked on.  Therefore, I want to put down a finish that will be quick to use and dry.  So one option wopuld be a water based poly, but I was wondering about using shellac instead.  It would be fast, and could be easily “repaired” as needed.  What do you think.  Thanks.
