Frequently Asked Flagstone Questions
Flagstone is most often used for patios, walkways, landscaping, walls, and on fireplaces. It is a unique stone that is not terribly expensive. This stone provides a very rustic, earthy appearance.
1. Can flagstone be used for countertops?
Flagstone can be used for countertops, though it used nearly as often as other stones such as granite, quartz, marble and soapstone. While the stone has a unique look, it is also very porous, and difficult to seal. That means the stone can stain and discolor easily.
2. Does Flagstone have to be sealed?
No. Many people don't seal flagstone. However, a sealer is suggested as it can greatly reduce staining. This is true for flagstone used indoors, or out. Preventing moisture damage can improve the overall look of the material, and reduce flaking.
3. What is spalling?
Sometimes called "flaking", spalling is when water permeates the stone, causing it to flake or peel off in layers and chips. Some spalling will stop naturally, other times the stone will continue to disintegrate slowly. Applying a sealer to the stone is the best way to prevent spalling. Ideally the sealer is applied at installation to prevent any damage. Avoid getting salt and other chemical on flagstone, this can also cause spalling.
