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.

Workability

Lithomex can be carved immediately or weeks after the installation.

The Lithomex Range

Lithomex comes in 24 stock colors and unlimited custom blends.

Used it to clean a former President and First Lady gravestones. Danby White marble. North sides were entirely green. Now, more white than they have been in decades.

I would caution that white marble will turn an orange color when used. As if someone poured rusty water over it. Don't panic, if you scrub, it'll go away quickly. If you spray and walk away, it might take a day or two. Great results though!

I do restoration and preservation work at an historic cemetery in southern Oregon. When we repair stone markers there are often pieces missing, large cracks above and below a breakage line, and damage or missing inscriptions. After some research I found out about Lithomex and gave it a try. I've been using it now for two years and it fits our needs perfectly.

The product meets the requirements in restoration for being the right type of mortar (i.e. lime-based without Portland cement), is easy to work and tool, and can be sanded or tooled for a number of days after installation. It comes in a number of common pre-mixed colors and can also be mixed on site to achieve a good color match.

That said, there is a learning curve. One has to learn how much water to add to get the best consistency for a given project, how long to wait until removing any forms, and how long after installation to wait until attempting to sand or do any tooling. Getting a good color match if mixing is required is also an art that just takes some experimentation and a careful methodology. It took me most of a work year (we don't work in the dead of winter) to begin to really feel comfortable but this year's projects look a lot better and went quicker.

It's not cheap but it's ideal for our needs and we try very hard to always use the best practices and materials. If you have a similar need you won't be disappointed; just give yourself some time to learn the ropes.

I’ve used D2 Biological Solution on 50+ monuments in my old cemetery while I was their sexton, & all I can say is, WOW what a difference. I would highly recommend this product if you were cleaning your families headstones or taking up the business of doing the same. It’s an amazing product.
