Hi, Byron. I hope you ask him how he does it and then come back and tell us. The polyurethane glues that I have used had to be clamped and the foam from the glue would come out every little opening in the joint even with the clamp. If you do not have the piece firmly clamped, the foam will push them apart. What will this do to your floor? If he has another kind of poly glue or a better way, I would certainly like to hear about it.
