1. Chips

• Identifying the issue: Chips are small pieces missing from the edge or surface of your countertop. They might occur from dropping a heavy object or bumping the counter’s edge.
• Materials you’ll need:
  • Color-matched granite epoxy kit
  • Sandpaper (several grits, from coarse to fine)
  • Razorblade
  • Acetone
  • Masking tape
• Repair steps:

• 1. Clean the area: Thoroughly clean the chipped area and surrounding surface with acetone to remove any dirt or debris.
  2. Mix the epoxy: Follow the instructions on your epoxy kit to mix the resin and hardener. Tint the epoxy to match your countertop’s color as closely as possible.
  3. Fill the chip: Overfill the chip slightly with the tinted epoxy, as it tends to shrink a bit as it dries.
  4. Let it cure: Allow the epoxy to cure completely according to the manufacturer’s instructions. This usually takes at least 24 hours.
  5. Sand and polish: Once cured, use sandpaper (starting with coarse and working down to fine grit) to sand the epoxy flush with the countertop. A wet sanding technique will help reduce dust.
  6. Clean up: Remove any excess epoxy with a razor blade and clean with acetone. You can enhance the shine with a granite-specific polish.

2. Cracks:

• Identifying the issue: Cracks in granite can be either hairline fissures or more obvious splits. Hairline fissures are often superficial and pose little structural risk, while larger cracks may require professional reinforcement.
• Materials needed
  • Color-matched granite epoxy kit
  • Sandpaper (several grits, from coarse to fine)
  • Razorblade
  • Acetone
  • Masking tape (optional, for large cracks)
• Repair steps:

• 1. Clean and prepare: Clean the crack thoroughly with acetone. For larger cracks, use masking tape around the crack to contain the epoxy.
  2. Mix and fill: Prepare the epoxy kit according to instructions, color-matching it to your granite. Carefully fill the crack with epoxy.
  3. Cure: Allow the epoxy to cure completely.
  4. Sanding and polishing: Sand the repaired area, ensuring it’s level with the countertop and remove excess epoxy with a razor blade. Clean and optionally polish.

3. Etches:

• Identifying the issue: Etches appear as dull spots or rings on your granite countertops. They occur from exposure to acidic substances like lemon juice or vinegar. Etches aren’t physical damage, but a change in the polish.
• Materials you’ll need:
  • Granite poultice powder
  • Granite polish
  • Soft cloths
• Repair steps:

• 1. Apply poultice: Mix the poultice powder with water to create a paste-like consistency. Apply generously to the etch and cover with plastic wrap. Let it sit for 24-48 hours as directed on the product.
  2. Remove and polish: Remove the dried poultice and clean the area. Apply granite polish and buff with a soft cloth for restored shine.

Tips for a Successful Repair

• Color matching: Do your best to match the epoxy with your counter’s color. Consider buying a kit with multiple pigments for better customization.

• Be patient: Epoxy takes time to cure fully. Don’t rush the process.
• Prevention is key Use cutting boards, coasters, and trivets to protect your counter from scratches, acidic spills, and heat damage.

When to Call a Professional
