And here it is below sanded. I wish there were a way they could have kept the paint while getting rid of the yellowish finish. Bummer. In fact, I sort of wish they had just left it alone.
But still, it ends up looking pretty nice after sanding too - just not as much character.
One thing that seems clear is that we don't need to plane it before installing it. Sanding will be just fine - although our flooring is a bazillion times more wrecked than this stuff. Our flooring lived under the watchful eye of a very different sign than the gym flooring enjoyed (ours and theirs, respectively):
What else did I find for recycled maple flooring?
Well, here's a good example of what I expect ours will look like installed - I found this at Longleaf Lumber:
The Longleaf Lumber website warns: "Expect character: nail holes, cart marks, and color variation."
These guys want $5.25@sq. ft. for reclaimed maple factory flooring!! and the stuff in the picture is very like what we got, though not as grimy. (suddenly I feel pretty smart)
And here is a site (BrownDogBuildingSupply) that sells "reclaimed foundry maple" floors:
"it shows the kind of honorable scars and marks you might expect from a life of service in a cotton mill, aircraft factory or pressing plant".
