Nope, I put a coat on the plywood and the carpet both. Let them dry for about 45sec-1min and stuck them together. Rolled them with a rolling pin and put some weight on it. Came back out the next morning after about 10hrs of drying and it just peeled right back up.
With the spray, I sprayed both sides. Let them dry for about 30sec and then stuck them together. Rolled them with the pin, and about 15mins later I could not pull it apart.
