Well, I'm going to try to find out. I've got about 8x8 on the floor I can cover easily, and that's about 1/2 of the 125 sq ft in the room. Have a couple pieces of ADX in the shed and might try that later...too busy with other stuff now, but I'll let you know if it was a waste of time when (if) I ever get it done.
Fun to watch you two. Not going to pick sides, just snicker a bit...
Wise man! What's ADX Ken?
