Product Details
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.
Environmental Requirements:
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.

Benefits:
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.
- Durable.
- 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.

Excellent product. I do preservation work on historic sandstone grave markers in Southern Illinois that have a distinctive tan color. The Berea Sandstone Lithomex has excellent texture and workability but tends toward the grey rather than tan color. I compensate by adding 1 t. of yellow color tint and 1/8 t. of red or brown per cup of mix. I wish there was a version of this in a tan color.
This stuff is fantastic. A concrete brick wall was severely damaged by water trapped under thick layers of paint. After I removed the paint I had no idea what to do with them. I did not want to make hundreds of replacement bricks. When asking about another issue Daniel suggested Lithomex for surface repair of the bricks. It worked great. I was even able to restore some details on the corner bricks with the Lithomex. Here are some pictures of the project. One shows the work in progress o the brick resurfacing. The next shows the column with replacement bricks (dark) and the Lthomex repair (white). The last two show the final wall with Lime paint.
It was easy enough to use but not trivial. This was our first time using it and we were very careful. We have some training (a CCUS class) but not in this product. We learned by reading how others used a similar product.
Shipping was fast. Product performed as expected! Thanks
Great product for repairing gravestones. Easy to work with, does a great job joining broken pieces of stone.
