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.

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.

Thomas and his team replaced some stones on the exterior wall of my listed house and removed some crumbling mortar before fixing the gaps. The end result is great – it blends in with the rest of the building perfectly and they were professional throughout the process. They worked quickly and efficiently, sticking to their promised time frame and budget!

Thomas and his team repaired, repointed and replaced the landing of our colony external stairs. As the render was removed from the step walls it became clear the steps were in greater disrepair than we thought. Thomas was quick to make the steps safe and clearly explained the additional works needed.

He also repaired some weathered stone work and removed old cement repairs repointing with the correct mortar.

Thomas and his team were polite and friendly and tidy.

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.

Thomas completely replaced the platform at the top of my Colony steps, repaired some of the steps, repaired the walls on either side and repointed the walls along the pavement. Everything was colour matched to fit with the original steps and I’m delighted with the final result.
Thomas and his workers were really great, friendly and polite and worked so hard to do everything just right. Thomas kept me informed every step of the way, was very thorough when finishing off and made sure everything was tidied up. A very positive experience!

Prompt, friendly and business like, Thomas checked out, assessed and estimated for repair of a dangerous broken step at the bottom of our common stairwell. Ahead of schedule and, at short notice, he resolved our problem to everyone’s satisfaction. TJF Stonemasonry is local to the Canongate and we would be more than happy to avail ourselves of their splendid services again. Highly recommended.

Thomas and his team removed cement mortar from a couple of elevations on a cottage. They then repointed using lime mortar. A brilliant job with minimal disruption. We have dry houses now! I would happily use Thomas Ferris again.

Extensive renovation work carried out to walled garden, including replacement coping, re-point and replacement bricks where necessary to match existing.
Very pleased with the work carried out by TJ Ferris. From the beginning, Thomas was very helpful, which made the decision process easy and the end result is excellent.
Costs were slightly above the original estimate but I believe they were honest in their approach and would not hesitate to use again.
