Stone & Plastic Repair

A blend of Lime, fine aggregate filler and additives forming various brands and specifications of conservation approved stone repair mortar designed for use on natural stone and period brickwork. It can be matched for colour and finish to almost any masonry.

Restoration and Repair Mortars

Specially formulated mortars based on Natural Hydraulic Lime and aggregates for the repair or simulation of masonry, brick or stone. Neutral white or pre coloured mortar supplied in 1KG to 25KG bags to which mixing water is added. Mixing and use: Can be mixed manually or mechanically by whisk, adding up to 180ml water per kilogram of Lithomex used. Mix well for 3-5 minutes. The application surface must be clean, free from dust and oils. On porous surfaces, ensure that suction is controlled by pre-wetting and apply Lithomex before this is fully dry. Never apply to surfaces that are over saturated or have standing water.

Shaping and forming of details can be carried out for up to 1 week after placing by scraping to profile or level with metal tools, such as the edge of a trowel or steel float however most shaping and finishing work can be done within 24 hours. Sculpting, using appropriate tools, requires waiting up to a week or more depending on the weather conditions. Its unique qualities allow it to be tooled, shaped and sculpted even after the final set has taken place. This affords sufficient time to achieve the very highest standard of work with the best quality reproduction.

Where ashlar masonry or very finely jointed masonry has had considerable damage to the arises, flush finishing in Lithomex with a false struck joint is the ideal solution. If building details are damaged and require repair prior to the facade being lime washed or painted, plain Lithomex should be used as it will readily accept lime washes and paints.

On rendered areas Lithomex can be used to form decorative stone or brick features such as mouldings and cornices.

Fantastic work on a decayed exterior window ledge. Good communication, great value and excellent job. Highly recommended.

Tom and his team recently finished a number of stone and building repairs at my house and I cannot recommend them enough. The job was complex yet Tom and his team provided me with a comprehensive estimate and plan which was followed through keeping us in budget. The craftsmanship was first class and Tom’s team were professional, courteous and tidy throughout. I could not be more happy with the job.

Very happy with the work done by Thomas and his team. The work involved some plastic repairs (lithomex) to my tenement wall to fix an area of stone that had delaminated and crumbled away. It was quite an awkward spot to get to as the access scaffold had to be built on another flat roof and the repair itself was high level, just below the gutter line, but they done a great job and got it sorted despite some very windy weather. I would recommend to friends and call on them again if the need arises.

Stone walling altered and gate inserted in 6 ft high wall. Also dry stone walling repaired.

Thomas did the work brilliantly. His workmanship is precise and to be admired.

I would not use anyone else for any further work we will from time to time need doing on our cottage and walled gardens.

We have used Thomas and his team several times do undertake stonework and other external repairs at Abbeyhill Baptist Church in Edinburgh. The building is over 100 years old now and the stonework needed significant work. Thomas undertook this work to a high quality, and several neighbours commented on how quiet the work was despite stonework repairs taking place. We have subsequently used Thomas’ services for other repairs to the building and recommend his services highly.
