Being a construction manager, I know that there’s an order that you should do things. Finishing the floor before the walls is not the correct order.
But … I did it in my own house. It just worked out that way with the timing of the availability of the guys to help me strip the floor and the guy I wanted to do the drywall work. I figured we could put down paper and drop cloths to protect the floor to during the drywall work.
That didn’t happen (because I decided to do it that way) and it worked out for the best.
After two coats of polyurethane … satin … on the floors, they turned out too smooth & slippery for my liking. I also need to fix a few spots where the poly dried a bit hazy.
I didn’t protect the floors for the drywall work since they needed to get sanded again anyway. They got a few more dings in them & heavy traffic with shoe soles full of drywall mud wore of the finish quite nicely. They are looking a lot more like that handscraped flooring that I originally wanted to go with. Once all of the drywall finishing & priming & painting are done, I’ll have them lightly sanded just to put on a thinned down coat of poly.
