Bonstone Match Epoxy Structural Stone Adhesive

Description

Bonstone Match Epoxy is a two-part structural stone adhesive for limestone, granite, Dutchman repairs, miters, and anchoring work. Bonstone lists a 2:1 mix ratio by volume, a 2 to 4 hour set time at 75°F, and a stone-safe formula that will not stain or wet out stone. The flowing paste consistency gives installers time to adjust parts before the bond sets.

Bonstone Match Epoxy Applications

• Bonding porous granite and limestone in shop or field repair work.
• Stone miter bonding where color and open time both matter.
• Anchoring limestone, granite, and related masonry details.
• Dutchman repairs and exterior stone restoration work.
• Laminating stone to steel, aluminum, or other construction materials after surface testing.

Use and Ordering Notes

Prepare stone surfaces so they are clean, dry, and free of dust or loose material before mixing. Keep the A and B components proportioned correctly, mix until uniform, and avoid stressing the repair until the epoxy has reached working strength. The source sheet notes full cure within 24 hours at 75°F, with slower set in cooler conditions and shorter pot life in hot conditions.

Use the kit size that matches the repair pace. Smaller jobs benefit from mixing only the amount that can be placed during the working window, while larger shop repairs need clear staging so the stone, clamps, tint materials, and cleaning supplies are ready before the A and B sides are combined. For visible work, always confirm color against the actual stone in job lighting before final placement.
