How to Repair Cracks, Fissures, and Scratches in Natural Stone

What causes cracks and fissures in a slab?
Cracks and fissures occur naturally in slabs during mother nature’s process of cooling the slab. At Aria, we inspect every slab in the reflection of the light to check for the cracks and fissures and only choose the stones with a very small percentage of natural imperfections, so this is not a typical issue you will run into with an Aria slab. However, it is important to know how the process of filling in cracks and fissures works so you will know how to spot them on a slab. 

How do you fix cracks or fissures?
Cracks and fissures are very repairable using a special epoxy that is meant specifically to fix cracks and fissures. Since the epoxy is very runny, the fabricator will carefully lay the slab on top of plastic and pour the epoxy over the cracks and fissures and let it set over night. During this time, the epoxy will go deep down into the crack and solidify. The next day, the fabricator will go in and either scrape off the residue with a razor blade or resurface the area completely, depending on the stone type and surface finish.

How do you fix surface scratches?
On softer materials, such as marble, onyx, and soapstone, even the best sealers are not stain and scratch proof. Before you call your fabricator, know that you have two main options: resurfacing the stone or using a stone color enhancer and sealer. With resurfacing being the more costly of the two ways to repair scratches on your natural stone, it may be a good idea to try to use the stone color enhancer and sealer first. Speak to your fabricator about what type of brand they recommend for your natural stone as far as stone color enhancer and sealer materials.

How does a color enhancer and sealer work?
Apply the color enhancing sealer to a dry rag and wipe in on top of the scratch and you will almost immediately begin to see the scratch disappear. The color enhancing sealer fills in and camouflages the scratch to make it much less noticeable.

How do I use a stone color enhancer and sealer material? And can I do this myself?
Of course we recommend that you first speak to your fabricator about this process in regards to your natural stone and advise you to read the instructions on the chemicals that you use. Also, as when introducing any new chemical or cleaning agent to your natural stone, it a good idea to test the how the stone will react to the chemical in a small, discreet place on your stone.

Many of the chemicals are easy and quick to apply and can be done at home. Start by putting the color enhancing sealer onto a dry, clean rag. Wipe the rag over the scratch and the scratch will disappear. Typically, you should let the chemicals sit for about five minutes, but this may vary dependent on stone, the size of the scratch, and the chemicals that you use. After the color enhancing sealer has set for about 5 minutes, come back and wipe with a clean paper towel until all of the excess product is gone. You can repeat this every three to four months.
