Our Repair Process
Cover and Protect Surroundings: Appliances, cabinets, and flooring were carefully covered to prevent dust or accidental damage.
Deep Cleaning of Granite Surface: We used our pH-neutral StoneShine cleaner to remove dirt, grease, and residue for proper repair adhesion.
Epoxy Crack Repair Application: A custom color-matched epoxy was applied to fill and seal the crack, restoring the surface structure and durability.
Diamond Sanding for Smooth Finish: The repaired area was sanded with diamond abrasives to even out the surface and blend with the surrounding stone.
Granite Countertop Polishing: We polished the entire surface to restore its natural luster, highlighting the stone’s original patterns.
Penetrating Sealer Application: A high-quality penetrating sealer was applied to protect the granite against future staining and moisture intrusion.
Final Buffing for Clarity: Excess sealer was buffed away, leaving the countertop with a clean, smooth, and durable finish.
