What to Know About Granite Crack Repair May 02 2016, 0 Comments

Some things are meant to be cracked, like an egg, a joke or a smile. But granite? Not so much. Considering its rich history, unique composition, and reputation for durability, it would seem to be a Herculean task to fracture this stone, perhaps a scenario involving a sledgehammer or an elephant, The truth is, there are much simpler ways in which you can damage your granite surfaces, some requiring granite crack repair as a solution.

As a competent DIY'er, you may want to add granite repair to your repertoire - just be sure you know what you're getting yourself in to before you begin, and you're armed with the right materials, products and advice.

How to Crack Your Granite
While most vulnerable to cracking during transportation or installation, it's entirely possible to damage your granite once it's in your home; here's how:

  • Stand on it. Use a chair or ladder vs. standing on your granite countertops.
  • Hire the wrong company to install it. Human error is the number one reason for granite crack repair. Hire a knowledgeable, experienced stone specialist for your granite installation; should the unthinkable happen due to an error during installation, a reputable contractor will stand behind their work and shoulder any necessary repairs. 
  • Chalk it up to bad luck. Natural fissures within the granite can weaken your stone, and crack with the right amount of pressure, or extreme heat; the natural acts of expanding, contracting and settling can also contribute to cracks.

Decide and Conquer
Once the damage is done, you have two choices:

  1. An out of the way, or insignificant hairline crack may be left alone, unlikely to get any worse. 
  2. Perform granite crack repair, either yourself, or by calling in a professional. 

Materials needed for a DIY repair:
A hole repair kit is all you need for the first phase of the repair. Your kit should contain:

  • Filler - only transparent filler is recommended for granite.
  • Hardener
  • Coloring tint
  • Stirring sticks, long and short
  • Flat toothpicks
  • Mixing cups
  • Straight-edge razors
  • Steel wool
  • Rubber gloves

7 Steps to Granite Crack Repair

  1. Gather your materials and clean the area with a multi-surface cleaner, formulated for use on granite.
  2. Open your can of filler carefully, making sure to not damage the edge of the container.
  3. Use a large stirring stick to transfer a small amount of filler in to a mixing cup, before replacing the lid on the can. 
  4. If you need to create a particular color, dip a flat toothpick in to the tint, adding tiny amounts until the desired color is achieved. 
  5. Open the hardener, stir and blend thoroughly. Place a small amount on the tip of your stir stick, and add to the filler. Mix the solution well for 1 minute to activate the hardener. 
  6. Take a long stir stick, and place some of the mixture in to the crack, Use a straight-edge razor to smooth and remove the excess from the hole. Allow to harden for 30 minutes before proceeding. 
  7. Use a small piece of steel wool to lightly remove residue from around the repair, but avoid rubbing directly on the filled patch.

After your granite crack repair is complete, the stone may need to be ground, polished and resealed, requiring the specialized equipment, knowledge and experience of a professional.
