Limestone Surfaces – How to Choose and Care for Them

When choosing worktops or other surfaces in your home, you will notice that there are a number of types of stone available. Choosing the right stone for you is just as important as understanding how much care is involved. Here’s what you need to know about limestone.


Limestone is made up of coral, shell and various forms of natural debris. Many people use them as worktops, flooring, backsplashes and more. You can even use them around your fireplace or hot tub. The only concern is that your limestone should not be overly exposed to water. That said, there are a few types of limestone that will be suited for installation in bathrooms and similar areas with high levels of water and humidity.

The Effect of Iron

Iron can be found in limestone slabs and, when it comes in contact with water, it will oxidise. This can result in stains over time and these stains cannot be removed. There is also no way of ridding the stone of iron because its is one of the many minerals that form part of the stone itself.


As soon as you install limestone, it is important that you have it sealed. You will also need to re-seal on a regular basis. If not, water will penetrate the stone and come in contact with the salts in the stone and, when it dries, the salts re-crystallise. This can result in flaking, peeling or even breaking on the surface of the stone.

Water-soluble materials

Limestone is known to contain calcium carbonate and other water-soluble organic matter. These materials will dissolve in the water over time and you will notice your stone start to disintegrate.

If you already have limestone in your home and it has suffered water damage, not to worry because you don’t necessarily need to replace it. Contact a professional for restoration services. You will find that it’s a lot easier and cheaper than replacing the stone.
