For thousands of years, natural stone has been a top choice for designers and architects looking for durable, superior building materials. Limestone structures like the Pyramids of Giza or the Great Wall of China are all the proof you need.

Sometimes, however, natural stone does show signs of wear and tear. If this happens in your home, don't worry – most cracks, fissures and scratches can be easily repaired. Here's how.

What causes blemishes in natural stone? 

Fissures occur long before natural stone is extracted or sold. They form when repeated cycles of heating and cooling lead to gaps between mineral crystals. Fissures may look like small, hairline cracks on the surface of your stone, but they're quite different.

While fissures occur naturally, cracks typically form due to mishandling or an accident. If you drop something heavy on your natural stone and it separates, for example, that would be a crack – not a fissure.

Many natural stone varieties have fissures on their surface which are of no concern. In fact, some homeowners even prefer this added character. A physical separation caused by human damage, on the other hand, is less desirable, not only because it looks bad, but because it weakens the surface and could worsen over time. 

To avoid cracks and fissures, start with the right supplier. At BauMart Natural Stone, we inspect every product and only sell top-quality stone with minimal natural imperfections. This doesn't mean, however, that our products can't scratch or crack later on. All natural stone is prone to damages, particularly in high use areas or if an accident or natural disaster takes place.

How to repair blemishes in your natural stone

Cracks and chips

If your stone has a chip or crack, there are a few options for repairing it: 

  • Clear resin,
  • Epoxy, or
  • Acrylic adhesive. 

Most prefer a special natural stone epoxy as it's easiest and most effective.

Begin by protecting the surrounding area with plastic as the epoxy can be very runny. Next, clean and dry the stone before pouring the epoxy over the crack and letting it set over night. The epoxy will penetrate into the crack and solidify. Then, you can remove any residue with a razor blade or other scraper.

Scratches

If you notice surface scratches, you can either resurface the stone or opt for a colour enhancer. Resurfacing can be expensive, so reserve this option for larger scratches. 

For minor surface scratches, apply sealer to a rag and wipe it over the scratch. Then, apply colour enhancing sealer to fill in the marks and make the scratch less noticeable. 

Don't go it alone

While these DIY solutions may sound straightforward, you need to be careful. If you choose the wrong cleaning chemicals or sealing products, you could make the problem worse.

Begin by calling your natural stone supplier who will be able to answer your questions and provide next steps. Sometimes, they'll even be able to put you in contact with someone who can fix the problem should the damage require an expert.
