Should I use clear epoxy or color-match it to the granite?

For small chips on speckled granite, clear epoxy acts as a optical window that reveals the natural stone color below. For large chips on solid black or white quartz, blending in a drop of dedicated stone epoxy pigment gives a better visual match.

Will a razor blade scratch my polished granite countertop?

Hardened granite (Mohs hardness 6 to 7) is harder than a standard steel razor blade (hardness 5.5). As long as you hold the blade at a low angle and keep it flat without digging the corners into the stone, it will shave the epoxy flush without scratching the stone.

Is cured epoxy food-safe on a kitchen countertop?

Fully cured 2-part epoxy is chemically inert and safe for incidental food contact. However, avoid chopping directly on the repaired spot with knives or placing 400°F pots directly on top of the cured resin.

What if I still have the chipped-off piece of granite?

If the broken stone fragment is intact, glue it directly back into place with thin clear epoxy or cyanoacrylate gel, hold it flush for 2 minutes, and wipe off squeeze-out with acetone.
