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.

I learned about D/2 from an article about a man who spends weekends cleaning old headstones, and that led me to LimeWorks. I ordered a quart to try it on our 1917 brick and stucco house and was immediately convinced that it is the answer to renewing any surfaces discolored by algae, moss, lichens, mold, mildew, etc. D/2 works like a charm! After my success, I ordered a quart for my brother-in-law in Illinois to clean family headstones, and I have now ordered a gallon to clean stucco in preparation for painting. I have used it so far on stucco, marble, ceramic tile, painted wood, concrete, and painted metal. My neighbor used some to see if it would work on mildewed asphalt shingles, and it did. I ordered an extendable 6'-24' soft car wash brush from Amazon for cleaning the stucco wall to avoid using a ladder. LimeWorks has absolutely excellent customer service; the gallon I ordered by phone yesterday will arrive today, and they have offered helpful advice and answered all my questions. (A local retailer sells D/2 but at double the price.) I've spread the word to our realtor, our handyman, a building inspector and a contractor. I could not be more impressed and satisfied!

Always the BEST folks to deal with when purchasing D/2, quick shipment and much better pricing than Amazon plus it is a friendly, brick and mortar company I would much rather support!

Our group purchases this product in large bag size but I wanted a small “official” container for at home/off site projects. Lots of work to do on this repair…
