Lithomex Brick and Stone Repair Material:
Lithomex is a specially formulated brick, stone, and terra cotta surface repair/ simulation material based on Pure Natural Hydraulic Lime and aggregates. Due to the presence of Natural Hydraulic Lime, Lithomex is porous allowing the composite repair to breathe. Furthermore, Lithomex comes in a neutral white or custom colored mortar supplied in 55 lbs (25kg) bags, which you can add mixing water too. Additionally, it is also available in units of 3 lbs or 15 lbs containers for smaller orders.
Users must follow the Manufacturer’s instructions when storing and handling materials to protect them from damage and moisture. In this regard, it is recommended to take necessary precautionary measures to assure excessive temperature changes do not occur. For instance, do not apply a patching mortar below the minimum ambient temperature of 45 degrees F and above the maximum of 85 degrees F. Furthermore, it is required that these temperatures are maintained for a minimum of 48 hours prior to the application and continue until Lithomex cures (for curing information please see the tech documents under “Data Sheets”). Likewise, during hot weather protect the repair from uneven and excessive evaporation during dry and hot weather. Finally, it is suggested to provide tarping over the outside of all scaffolding.
Available in natural and 24 Stock Colors.
Lithomex’s unique qualities allow you to tool, shape and carve it even weeks after the final set takes place. As a result, this affords sufficient time to achieve the very highest standard of work with the best quality reproduction. For successful surface repairs, the materials employed need to have certain characteristics.
Above all, these materials should have the following qualities:
- Have characteristics sympathetic to the host masonry.
- Attain an adequate bond strength.
- Have a good modulus of elasticity.
- Vapor permeable.
- Capable of dressing with similar tools to the original masonry.
- Remain workable long enough to allow details to be fashioned.
- Match in color and texture.
- Repairs are always reversible.
Patching stone is very effective, affordable and can be reversible. The brick and stone repair/patching material must match the color and texture of the existing stone. As a result, the material must adhere well, process moisture, and have similar thermal expansion and weathering characteristics to the hose masonry. Lithomex will lend itself to a perfect match when a skilled craftsman is applying it. Lithomex fulfills these requirements in most cases.

It is suggested that you purchase the St. Astier Lime Paint Swatch to see the actual color. By purchasing the Paint Fan Deck you may view each swatch in the deck individually or hold one or more of these swatch cards to the surface of the wall to ascertain which stock color may be most appropriate for your application.
