Abstract: The liner for concrete forms is a plastic matrix for simulating the mortar grooves conventionally formed in masonry construction. The liner is placed within a concrete form, and the concrete is poured thereover. The form is removed after the concrete sets, thereby exposing the surface with the liner still remaining therein. The surface of the concrete panel may then be treated as desired to produce a surface finish resembling brick or other masonry construction, e.g., sandblasted or coated with stucco or other material, with the liner remaining in place to protect the simulated mortar grooves. Once the surface of the concrete panel has been treated as desired, the liner is removed to expose the natural concrete surface within the grooves, with this natural concrete surface closely resembling the mortar joints in a masonry wall.
