What to look for in a historic restoration patching material.

A patching material must match the color and texture of the existing brick and stone. It must adhere well, be breathable, and have similar thermal expansion and weathering characteristics to the host material. Lithomex fulfills these requirements and in most cases, when applied by skilled craftsmen, will lend itself to a long lasting and perfect match.
