Refinishing the floors in the loft were super easy compared to the floors in the loft bedroom. For prep, we just swept the floors with the wet/dry vacuum and mopped the floor. Once it was dry, we put on 2 coats of polyurethane, letting the floor dry in between coats. The polyurethane was just the cheap stuff but it did a fantastic job and went on super heavy.
Here's how the loft floor looked before:
and here's what it looked like after one coat of polyurethane:
Also, we put up a new railing, which I'll cover on another post. That weird spot in the middle of the floor is where we forgot to put polyurethane on the first time! We fixed that in the second coat! #professionals
Here is the new floor and old floor together. This is before we put polyurethane on the new floor. It's not a total match, but fairly close for being done 25+ years apart!
