What to look for in a lime patching material for historic restoration.

A patching material must match the color and texture of the existing brick and stone. The lime product 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.


Lithomex can be carved immediately or weeks after the installation.

The Lithomex Range

Lithomex comes in 24 stock colors and unlimited custom blends.
