Durock 1/4 in. x 3 x 5 ft. Interior Cement Board

CGC Durock Brand Cement Board Underlayment is an ideal substrate for floor and countertop ceramic tile installations. The 6.4 mm (1/4″) thickness helps eliminate transition trim when abutting carpet or wood flooring and minimize level variations with other finish materials. It can be applied directly over old substrate on countertops to save time. It features formed smooth edges and square-cut ends.
