Backerboard for ceramic tiles and the like

摘要

A rigid backerboard for replacement or substitution for a cementuous backerboard. The board is formed of a compression molded plastic material, preferably nylon which is relatively thin, yet rigid. The board is embossed on both of its principal (upper and lower) surfaces to maximize surface area for contact with adhesive materials. The embossment on at least one of the sides is rectilinear, facilitating the cutting of standard sized rectangular panels into smaller rectangles. The embossment on the opposite side is designed to maximize adhesive contact area, a diamond pattern being preferable.
