No, we did not apply thinset it is just screwed, lots and lots of screws.

Weyerhaeuser thinks we have TJI 250s from the late 80's, I too thought SP 15. It's the marking on the webbing throwing everyone off. Also LVL.

Even with worst-case scenario, I think we are over the 480 mark, but by how much. The general consensus is that we are fine, I would like a number and the math hurts .

I think we will pull up the backer board this weekend.

Getting to this point was hard, I'll reinforce the joists for this slate.

Also, I'm in Maryland, Eastern Shore area.
