ScratchBond 8200 is a Portland-cement-based scratchcoat mortar for use with metal lath on plywood subfloors and countertops prior to setting ceramic tile and stone. Use it with metal lath fastened to exterior-grade plywood to create a “semi-floating” underlayment system, reducing the potential for in-plane cracking of installed ceramic or stone.
