How to Repair and Reinstall Tombstones and Monuments Using Epoxy

Broken Tombstone in Need Of Epoxy Repair

Preserving Memories with the Right Materials

Tombstones and cemetery monuments are more than stone markers — they are lasting tributes to loved ones, meant to endure for generations. Unfortunately, time, weather, and accidental damage can leave even the most carefully placed monuments cracked, broken, or leaning dangerously.

With the right materials and a careful repair process, you can restore these memorials with strength, beauty, and dignity.

Epoxy.com Product #2005 — a semi-flexible, high-strength epoxy — is specially designed to bond stone while allowing for the natural movement caused by weather and temperature changes.

This guide will walk you through the complete installation and repair process, from preparation to final placement.

Why Tombstones and Monuments Break

Understanding why these repairs are needed is the first step to a successful restoration. Common causes of tombstone and monument damage include:

Freeze/thaw cycles causing cracks and movement Settling soil that shifts the base and foundation Vandalism or accidental impacts Previous repairs done with the wrong materials (brittle adhesives or rigid epoxies that fail over time)

Because natural stone expands and contracts with temperature changes, using a semi-flexible epoxy — Epoxy.com Product #2005 — is critical to long-term success.

Why Choose Epoxy.com Product #2005

Superior Flexibility: Moves with the stone as temperatures change Outstanding Bond Strength: Holds even under outdoor exposure and weight Excellent Weather Resistance: Resists freeze/thaw, rain, and UV degradation Easy to Work With: Mixes and applies easily for professionals and skilled DIYers alike

Choosing the wrong adhesive can lead to rapid failure. Product #2005 was designed specifically for the realities of monument and tombstone restoration.

Materials Needed

Epoxy.com Product #2005 (Flexible Epoxy Adhesive) Mixing containers and mixing sticks Stone dust or finely crushed stone of similar color (for seam blending) Clamps, straps, or bracing (depending on stone size) Rags or paper towels Acetone (for cleaning excess epoxy before it cures) Stiff brush Level Gloves and eye protection

Step-by-Step Repair and Installation Guide

1. Inspect and Prepare the Broken Stone

Examine the broken faces of the stone carefully. Remove dirt, loose particles, surface contamination, and old adhesives with the gentlest possible method to ensure a clean bond. Refer to our Surface Preparation Guide for more details on effective cleaning techniques. Dry fit the pieces together to ensure a good match before applying any epoxy. If surfaces are wet or damp, allow them to dry fully before proceeding.

2. Mix Epoxy.com Product #2005

Follow product instructions carefully for the correct mix ratio. Mix thoroughly in a clean container until fully blended. Only mix what you can apply within the product’s working time.

3. Apply the Epoxy

Apply a thin, even layer of mixed epoxy to both faces being bonded. If the stone is highly porous, a slightly heavier application may be needed.

4. Assemble and Align

Carefully press the two faces together. Wiggle slightly if needed to help the epoxy fill voids and create full contact. Wipe away any excess epoxy immediately with a rag dampened with acetone.

5. Secure the Repair

Brace epoxy repaired stone until cured

Use clamps, straps, or temporary braces to hold the pieces firmly in place. Be careful not to overtighten — you want good contact without forcing the stone to shift or fracture. Ensure the repaired monument is level and properly aligned.

6. Finishing Touch (Optional)

To make the repair nearly invisible, blend stone dust or finely crushed stone of a similar color into the uncured epoxy at the seam. This step can dramatically improve aesthetics, especially on visible front-facing repairs.

7. Allow Proper Curing Time

Allow the repair to cure fully per Product #2005 instructions before moving or stressing the monument. Protect from rain or freezing temperatures during cure, if possible.

Common Mistakes to Avoid

Using rigid, brittle adhesives not suited for stone expansion/contraction Poor surface preparation (dust, dirt, or moisture can weaken the bond) Not aligning pieces properly before the epoxy begins to cure Skipping curing time — full strength requires patience

For best practices, be sure to review our Do’s with Epoxies and Don’ts with Epoxies.

Taking care at each step protects the monument and honors the memory it represents.

Monument Repairs with Epoxy

March 9, 2016

A technician who uses a non-Epoxy.com product to repair tombstones wrote me recently looking for help with problems that he was having. He goes on to say that the epoxy that he uses never fails, but rather the stone fails. When a secondary break occurs, the stone always re-breaks about 2 mm (about ¾ inch) above or below the epoxy joint. The epoxy attached to about 2 mm of the stone and holds well.

He asked me if the epoxy shrinks so much that it will ‘ pull away ‘ from the stone it’s attached to, and in his case, it pulls about 2mm of stone with it.

No I doubt it is epoxy shrinkage causing the problem. High quality epoxy has little or no shrinkage. It would have to be a very poor quality epoxy to be shrinking enough to do that.

The reason his epoxy is not working is that it is too rigid. His existing rigid material has a “high modulus of elasticity”. A material with “high modulus of elasticity” is a material that is stiff and/or rigid. A “low modulus of elasticity” material is semi-flexible, and is not rigid or brittle.

T pieces of the stone structure (in this case a tombstone) and pieces not in touch with the ground tend to get hotter and cooler faster than the larger pieces and pieces with ground contact. This is called “differential timing of the event”. For example the top of a tombstone can be heated and cooled on 5 sides, the top and the 4 sides. The base of the tombstone which is buried in the ground has earth or stone on all of its surfaces. This earth and stone tends to keep the temperature of the base more stable by insulating it and slowing the change in temperature. This works much like the insulation in your house slows temperature changes inside your house.

When an object like a piece of stone is heated it expands (gets bigger). When an object cools it contracts (gets smaller). For example 100 feet of concrete will be 1 inch longer once it is heated 100 degrees F. That is why expansion joints are cut into concrete.

In the case of tombstones all the pieces of the same type of stone have very similar if not identical “coefficient of expansion”. Since the pieces are positioned with potentially different timing of heating and cooling there is a “differential timing of the event” (see above). The result is stress areas you are seeing in the closest weakened plane in the stone near the bond line.

Product #2005 was specifically designed for tombstone (monuments) and/or stone bonding, or repair. Epoxy.com Product #2005 is very strong yet it is has a “low modulus of elasticity” (semi-flexible). The low-modulus of elasticity helps to absorb differential movement (two sections of stone heating and cooling at different times), making it much less likely to cause a stress area in adjacent weakened planes.

Camouflage the bond line rubbing stone dust(ground off the original stone or a similar colored stone) into any exposed epoxy material while the epoxy is still “wet”. That way the dust will stick in the wet epoxy making the epoxy difficult to impossible to see.
