Granite countertops are one of the most durable surfaces available for your kitchen. But sometimes, even the toughest stone can develop small cracks or chips. Don’t worry, fixing them is easier than it sounds.
To repair cracks in granite countertops, simply clean the area, fill it with a clear epoxy or resin, let it dry completely, then gently sand, polish, and seal the surface. This restores smoothness and prevents further damage
Why Do Cracks Appear in Granite Countertops?
Granite is strong but not unbreakable. Over time, everyday activities can cause stress on the stone. Here are the most common reasons cracks appear:
| Cause | Description |
| Heavy Impact | Dropping a pot, pan, or appliance on the surface |
| Heat Shock | Placing hot cookware directly on cold granite |
| Improper Installation | Uneven cabinet support under the slab |
| Natural Weak Points | Veins and patterns that form during stone cutting |
| Age & Wear | Small stress cracks are developing over the years |
Even a small crack can allow moisture to seep in, which may lead to stains or further damage. That’s why early repair is key.
Tools & Materials You’ll Need
You don’t need fancy equipment. Most of these items are available at local hardware stores.
- Mild dish soap and warm water
- Soft cloth or microfiber towel
- Granite repair kit (with epoxy or resin)
- Razor blade or putty knife
- Painter’s tape
- Fine-grit sandpaper (400–600 grit)
- Polishing compound
- Granite sealer
Tip: Always choose a clear epoxy or resin that matches the color and pattern of your granite.
Step-by-Step Guide: How to Repair Cracks in Granite?
Let’s fix it! Follow these easy steps carefully for the best results.
Step 1: Clean the Surface
Wipe the cracked area with mild soap and warm water. Remove grease, dust, or food particles. Dry it completely with a soft cloth. A clean surface helps the repair material stick properly.
Step 2: Tape Around the Crack
Use painter’s tape to protect the surrounding area. This keeps the epoxy from spreading onto clean parts of your countertop.
Step 3: Mix the Epoxy or Resin
Follow the instructions on your granite repair kit. Usually, you’ll mix resin with a hardener. Stir slowly until it’s smooth and consistent.
Step 4: Fill the Crack
Using a putty knife or toothpick, apply the epoxy directly into the crack. Fill it and make sure no air bubbles are trapped. For deeper cracks, you can apply in layers.
Step 5: Let It Dry
Allow the epoxy to harden for at least 24 hours. Avoid placing anything heavy or wet on that area during this time.
Step 6: Smooth the Surface
Once the epoxy is dry, gently sand the repaired area with fine-grit sandpaper. Be patient and work lightly, you just want it level, not scratched.
Step 7: Polish and Shine
Use a granite polishing compound to restore shine. Apply with a soft cloth and buff until the repaired area blends with the rest of the countertop.
Cleaning and Restoring Granite Surface
After repair, proper cleaning keeps your granite fresh and bright. Avoid harsh chemicals like bleach or vinegar, as they can dull the surface.
Instead, use a granite-safe cleaner or make your own: mix mild dish soap with warm water. Wipe daily and dry with a microfiber cloth.
If your surface looks dull after some time, consider granite cleaning and restoration from professionals like Superior Granite. It removes buildup and restores the natural glow.
Sealing and Polishing After Repair
Granite sealant acts as a protective layer against stains and moisture. Once the repair area is fully dry and polished:
- Apply a thin layer of granite sealer using a clean cloth.
- Let it sit for 10–15 minutes.
- Wipe off any extra with a dry towel.
- Buff gently to bring back shine.
Therefore, granite sealing and polishing should be done every 12 to 18 months to maintain strength and shine, especially in kitchens with high activity.
Removing Granite Stains the Easy Way
Cracks often collect stains from coffee, wine, or oil. Here’s a simple home fix: Make a paste using baking soda and water for oil stains, or baking soda and hydrogen peroxide for water-based stains.
Spread the paste on the stain, cover it with plastic wrap, and leave it overnight. Wipe clean the next day. This trick works beautifully for removing granite stains without harming the stone.

FAQs
Q1: How long does it take to repair a granite crack?
Usually, 24 to 48 hours, depending on the epoxy drying time.
Q2: Can I use super glue instead of epoxy?
No, super glue is too brittle and won’t last. Always use a granite repair kit.
Q3: Will the repaired crack be visible?
If done carefully, small cracks blend very well. Professional repairs are nearly invisible.
Q4: How can I prevent cracks in the future?
Use trivets under hot pans, avoid dropping heavy objects, and reseal your granite yearly.
