Patching & Repairing Indiana Limestone
Indiana Limestone is a forgiving material. It will take surprisingly hard knocks and rough treatment without damage. However, breakage occurs from time to time and usually it can be repaired easily with a little know how and the right tools.
The best treatment is prevention. Careful handling in all stages – loading, transporting, unloading, stacking, handling and installation – will avoid most damage and will produce the quality installation associated with Indiana Limestone.
Save the chips!!!!
Damage in the form of chipped edges is the most common type and is the easiest to repair. If the chips are minor and occur on stones not in prominent sight in the building, it may be best to leave them untouched.
Often such small chips may be sanded away by rounding the edge of the stone. This procedure may require the architects approval.
When chips can be saved in one or two pieces, they can be glued into place successfully using a high strength waterproof adhesive. While epoxy or other two part adhesives are usually employed for this purpose, small chips can be held in place by common waterproof white glue. Whatever material is used, take care that the joint line is as tight as possible and that no adhesive smeared on the adjoining faces. After glue dries, touch up with light sanding to complete the repair.
For even more information and detail on how to repair damage to Indiana Limestone, see this fine publication from the Indiana Limestone Institute.

Ernie’s Two Cents
Recently, we’ve had some issues with the chipping of stones when they arrive at the job site. In our facility we strive to send out a quality product free of chipping and any other issues. Once we load it onto the trailer, it belongs to the customer. It is the responsibility of the customer to inspect and check for any damage of the product once it arrives. Any such issues should be noted on the Bill of Lading. Any stones that are deemed to be too damaged for installation SHOULD NOT BE INSTALLED. If they look that bad on the pallet, think of how they will look in the wall. Repairing after the fact and taking the chance of having the stone rejected is much more costly than having it replaced and/or repaired PRIOR to installation.
We have several miscellaneous overstock cut stone pieces in our bone yard. Some of these are left over from a job, some are cut & then the dimensions change, whatever the reason….we have several items that might be of interest to some of you.
Our feature project this month is a beautiful hand carved memorial stone. Duplicated from a 3’ tall resin mold, this memorial stands over 8’ tall and is the largest in the Central Indiana cemetery in which it rests.
