Description
Bonstone Silk epoxy is a two-part, translucent white structural adhesive for laminating light-colored marble, granite, quartz, and engineered stone. The pale cured appearance helps the bond line remain discreet in miters, built-up edges, and laminations where a dark adhesive could show through or create a visible shadow. It can also join stone to compatible construction materials in interior and exterior assemblies.
Stone Fabrication and Lamination Uses
This formula fits countertop fabrication, mitered edges, stone build-ups, architectural panels, and repairs where clarity and color control matter. It is designed for vertical and horizontal applications and can be tinted with Touchstone liquid tints when the project requires a closer color match. Improved color stability supports light stone work, while the cured bond is suited to humid environments and freeze-thaw exposure when the joint is correctly designed and prepared.

Dry-fit the pieces before mixing and confirm that the joint closes evenly. Remove dust, oil, moisture, polishing compound, and weak material from the bond area. Measure both components at the stated 2:1 ratio and mix until color and consistency are uniform, scraping the sides and bottom of the container. Apply enough material to wet both surfaces without trapping large voids, assemble the joint, and support it until the epoxy has set. Cooler conditions can extend cure time, so verify the assembly before machining or moving it.
Always test tint, bond-line appearance, and adhesion on an offcut from the project stone. Porous or translucent materials can reveal color differently after cure. Explore related epoxy adhesives for alternate viscosities and working times. Additional company and product-family information is available from Bonstone stone repair and fabrication materials.
