Lithomex is a type of pre-mix mortar used in stone repairs. Based on natural hydraulic lime, lithomex comes in custom colours.
Stonemasons buy lithomex in 25kg bags or 4kg tubs. A stone mason will use this type of mortar as an alternative to concrete mortar.
So unlike concrete, lithomex is not damaging to soft stone and is flexible and porous. It therefore allows the building work to breathe.
Being a flexible and versatile medium, the mortar mix comes in a variety of natural colours. This is great for seamless stone repairs.
Manufacturers will use natural mineral pigments to create the right colour for your stonework. If you have not seen the colour in nature, the chances are that you will not find manufacturers can make the colour for their lithomex mix.
Hence you will not be seeing bright pink or any other unnatural colour within walls in Scotland anytime soon.
Protecting Lithomex Mortar
Right before any work commences, we check the entirety of your outdoor structure. We ensure all repairs will be successful and protected.
Whilst the mortar is being applied and cured, we use protection measures. This ensures your new mortar will dry evenly and safely.
- Ground drainage
- Roof Membranes
The idea is to allow the moisture to pass through the mortar so the wall dries quicker and safer. However, we avoid rapid drying by ensuring the new mortar is not in direct sun or heating, wind, in freezing temperatures, or exposed to rainfall.
For Professional masons only
Manufacturers make this pre-mix mortar from lime. It therefore carries a hazardous material warning.
Before lithomex sets, it can be highly dangerous to health.
The main issues with this unset mortar mix are:
- Can cause skin burns and eye damage when humid or wet
- May cause cancer
- Causes damage to lungs through repeated exposure (inhalation)
Therefore, it is vitally important that only professional stonemasons are able to use lithomex for stone repairs. Like Morningside Masonry’s staff, who have been highly trained over many years.
