Looks like we may use an epoxy paint with
colored flakes in it for floor. There isn't many products that can withstand the changing temperatures and lay on a less than flat floor. Vinyl would have been an option except the school desks cast iron feet would tear it up.
So after the ceiling, I will probably be crawling under the school house to check supports for floor. I am sure more will need to be added. I am hoping we get some warmer weather soon as much of my next work will be outside.
The last picture is just a cool icicle on our back porch roof. It is about three foot long. I had to knock it down so it didn't kill, Speck the Chihuahua on one of his trips outside. Lee Anne would never forgive me if I killed her dog while she was gone.
