Lithomex-what it is, and why we use it

We use only the latest natural, breathable, lime based materials, such as Lithomex and Façade 400, for stone repairs. They can be specifically colour matched to the clients stone in several shades, so as to blend in with the existing surface.
We remove any loose surface material and dress the stone back to a sound base. The stone is then dampened and wet Lithomex is applied. 
We then shape and sculpt the Lithomex as it slowly cures, to give an extremely authentic restoration. ​

​Lithomex stone repair mortar is the  product we use to repair damaged stone. It is completely lime based.
The common practice of using cement based renders for repairing delaminated and eroded weathered stone, creates an inflexible and non-breathable finish, trapping water and salts within the stone, and eventually leading to cracking and separation from the wall, and thus causes great damage to the underlying stonework. Lithomex contains no cement.​

Why nobody notices our repairs

We believe that stone repair should be as near invisible as possible, and we make sure the repairs match the existing colour and texture of the weathered stone and not as the stone would have looked if new.
We can, if required, add weathering, veining, clay-pockets, saw-marks, and small imperfections to our repairs, to give a more authentic look. We can repair any stonework, be it ashlar, rubble,  sandstone, granite, and replicate any finish, be it mouldings, French drag, or smooth. We can do whatever the client requires.
​ Lithomex is a wonderful product but requires many years of experience and training to produce a high quality finish. It is a specialist material. In the wrong hands a repair can look worse than the original damaged stone.
Please take a look at the hundreds of examples on our website, including our Lithomex gallery.

‘I approached Mountain Stoneworks for a quote, beside two non-specialist builders, for replacement of the unsightly and damaging cement repair mortar on my sandstone-built house with lime mortar pointing. I expected their quote to be the highest and was amazed when it beat the others, but quality was not to be sacrificed.'
