Repairing damaged stonework begins by identifying and understanding the reasons for decay. The usual reasons are excessive moisture, poor repairs, mechanical damage and natural decay. A major reason for damage is inappropriate repairs. Hard pointing or cement-based repair materials are very damaging to soft stone. Lithomex, a lime-based material, is flexible, porous, and lets the building breathe. Hard cement-based materials trap in moisture and salts. Patching stone can be very effective, affordable and can be reversible. The patching material must match the color and texture of the existing stone. It must adhere well, be breathable and have similar thermal expansion and weathering characteristics. Lithomex fulfills these requirements in most cases and, when applied by skilled craftsmen, will lend itself to a perfect match.
