This info-graphic titled ‘5 steps to restore Limestone floors from chips and cracks’ provides us an overview of restoration of limestone buildings.

One hundred million to five hundred million years old, limestone is traced from fossil deposits of marine animals. It generally has a unvarying consistency and texture and is usually buff or off-white in color, but it can also be gray or very light in tone of color.

While durable, limestone can be damaged by age, neglect or extremely heavy use. Alkali stains can cause discoloration when alkali-charged wetness permeates the limestone from its back or bottom bed. Efflorescence can happen when moisture picks up traces of sodium, calcium, magnesium or iron sulphate from within the wall. This can cause the fabrication of a whitish bloom or powder on the stone’s surface, flaking and exfoliation.

In some cases, artists take tracing of remaining pieces of the actual stonework and transpose the designs to fit into missing sections of limestone. While in order to repair pits or tiny chips, special mortars and layers of sealants are applied and then sanded, and, perhaps, painted to blend with the surrounding stonework once the repair has set.
