Specially formulated brick, stone and terracotta patching
material based on Natural Hydraulic Lime.
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.
