How to care for your limestone

Limestone is a beautiful building material that requires special care to keep in top condition. Limestone is a sedimentary rock containing all three main sedimentary structures: grain, clast, and matrix. It’s made up of calcium carbonate (CaCO3) mineral crystals, usually microscopic in size. The stone is split into two categories: calcined limestone and dolomite lime.

This stone has been in existence since antiquity. Limestone was used in the pyramids, the Great Wall of China, and temples in Tibet. Although stronger materials exist, this beautiful stone is still used in public spaces and homes worldwide. Here are some tips for caring for your limestone. 

Caring for indoor limestone

Despite feeling solid compared to other materials, Limestone is a porous stone. This means that it absorbs water like a sponge.

It’s best to avoid spills and moisture by placing mats under furniture with limestone surfaces. If you have a spill, blot up any liquid immediately with a clean cloth or paper towel.

Use a commercial cleaning product or mild soap and water to clean your indoor limestone surfaces. Do not use harsh chemicals or sharp objects to try and lift stains.

If you have limestone floors or counters, it’s essential to seal them with a deep penetrating sealer to protect against damaging elements.

Caring for outdoor limestone

Outdoor limestone is likely more abused due to the sun, rain, and other environmental factors. Despite this, it can stand the test of time if maintained well.

To clean limestone, first clear off loose dirt and debris. Then you can use a power washer on a low setting. Abrasive tools, like power washing machines on too high of a setting, will damage the stone. If there is still staining, use soap and water.

To keep your outdoor limestone looking its best, you should seal it with a penetrating sealer every two years. This will help protect against acid rain and other damaging elements. If you have a limestone facade, you will likely have to hire professionals to clean or restore it.
