You just stagger the joints. For a footprint of 8' x 5', the top layer could be (2) 4'x5' pieces. While on the bottom you could have (3) 32" x 5' pieces or (2) 8' x 30" pieces.By 2 layers do you mean staggering the bonds? e.g. , the bonded side in front on the bottom layer, and the second layer having the bond in the back? And where can I buy MAX BOND THIXOTROPIC?
They sell MAX BOND, along with MAX ACR on Ebay.
