Cleaning and Protecting Limestone


Cleaning and Protecting Limestone

There are many methods to clean cut limestone. We will discuss the most common methods below.

Fiber brush and soap powder: Among the most common of methods are washing the limestone with a fiber brush and soap powder, followed by a thorough rinsing with clear water.

Pressure washing is another popular option, and often the required water pressure can be delivered from ordinary hose taps. Greater water pressure can be used in some situations if delivered by a wide-angle nozzle from a distance no closer than one foot to the stone surfaces.

However, a lower pressure and greater distance will be equally effective. Suppliers or trade associations representing the specified limestone should be contacted for pressure recommendations for their particular product.

Avoid Acids and other Harsh Treatments:

Special consideration and protection should be provided when brickwork is cleaned above the limestone. Strong acid compounds used for cleaning brick will burn and discolor the limestone.

In general, sand-blasting, wire brushes or acids should never be used on limestone. When circumstances arise that cause one or more of these methods to be considered, suppliers or trade associations representing the specified limestone should be contacted for recommendations.

Protect your Stone During Renovation:


During construction, tops of walls should be carefully covered at night and especially during any precipitation or other inclement weather. At all times, walls are to be adequately protected from droppings. Wooden covering can also be placed to protect the stonework. Nonstaining building paper or membrane should be used under the wood. Maintain all covering until removed to permit the final cleaning of the stonework.

Take care to ensure protection of your limestone throughout the renovation process.
