As an option to stone replacement where a stone is found to be eroded is the use of Lithomex Stone Repairs. Lithomex is a specially formulated lime based stone repair mortar, which when dry very much looks like and acts like stone. When set, lithomex takes on all the attributes of natural stone such as similar looks, texture, water permeability and probably most importantly, expands and contracts the same as stone at a given temperature etc. This ensures it stays stuck to the host masonry. Lithomex is the best product of its type for carrying out stone restoration and repair, and we only use Lithomex here at Stonemason Fife.
