Limestone is a beautiful and iconic stone that’s popular for buildings, walkways, stairs, patios, and pool and deck landings. It’s certainly a stone that can stand the test of time, but it also can stain, discolor, or be damaged due to dirt, grime, moisture, and deterioration.

Cleaning limestone

Limestone is a soft and porous stone, which makes it even more susceptible to stains and deterioration than other stone materials. Unsealed limestone can be easily damaged by using the wrong cleaning product or method, whether harsh chemicals or high-pressure washes. Sealed limestone can be cleaned more easily, but caution is still advised.

Avoid acid-based cleaners on limestone, as the acid can deteriorate the surface. In most cases, a mild detergent and water are sufficient to clean limestone, but any damaged areas of the limestone should be repaired prior to cleaning. It’s best to consult a professional for limestone cleaning projects to ensure proper care.

Inspecting limestone for damage

Limestone repair can be costly, but preventative maintenance can help identify minor issues for repair before they become major issues. A limestone exterior should be inspected for any discoloration, flaking, cracks, chipping, or erosion. Standing water near limestone walls should also be resolved quickly to prevent saturation and staining.

Sealing limestone

Using an appropriate coating can help seal limestone and make it less porous and less susceptible to staining and damage. While coatings on some stones result in a shiny finish, sealers applied to limestone penetrate the stone so the surface retains the look of a natural stone while still being protected.

With proper cleaning, regular inspections and maintenance, and the right protective coating, your limestone exterior can withstand the elements and keep its natural beauty for years to come.
