Spray foam and subfloor

James and I masked off the plumbing:

Then we got suited up, and set up the spray foam, after eating a delicious lunch (not shown):

We didn't take any pictures while doing the spraying, because it was really complicated, but here we are, halfway done, moving the tanks:

You see, we had to spray a layer of foam in, and then quick, while it was soft, set the rigid foam on top, and then weight it down with a board, and if necessary, stand on it. We also had two boards that we were moving before each spray, to protect the tops of the joists from overspray. And I couldn't stop spraying for more than 30 seconds, or the foam in the nozzle would harden. It seemed like it was going to be really hard, and we rehearsed it to figure out how to do it. And we prayed about it. And, Praise God! it worked really well! We could see God at work, making possible a task that seemed too hard for us.

When the foam was done, we started on the decking.

 James and I cut and screwed down much of the decking today. It was hard to get all the screws in, but it worked out. We used battery drills, and a corded drill. The corded drill worked well to drill the self-drilling screw into the steel joists, but the battery impact driver finished them off better, with its incredible torque:

We glued down the subfloor to the joists. At the edges, we put sill seal, with glue on both sides. Here I am, putting down glue before placing a sheet:

Beth filled some left over gaps in the insulation, using Great Stuff:

 Using a scraper to clean off the excess, and put it where it was needed:

Then she sealed the decking with caulk. Hopefully this will help keep out the rain until we put on a roof.

It was a full day of foam and decking. Thank you James, for your help!
