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.

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 men repointed the front of our bungalow, repaired a stone widow sill and replaced some rendering. Despite the current covid situation causing a delay to the start of the work, the work was carried out efficiently and smoothly. I cannot fault the quality of the finish and the workmen were friendly and hard working. Overall we’re very happy to have chosen Thomas for the work.

Repaired external stairs – work was completed with excellent masonry skills, on time and within budget. What else can you ask for. Highly recommend you use Tom Ferris Stonemasonry.

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.

Stone repairs, replacement of ridge tiles and pointing of chimneys and wall heads.
Excellent service. I have used TJ Ferris Stonemasonry on a number of occasions now and would not hesitate to recommend this company both for the work done and value for money. Both Thomas and Blake are excellent workmen.

I have experience of T J Ferris Stonemasonry’s work both in repair and new stone build. The quality of their workmanship is excellent. They have built a new stone wall for me personally and we are very pleased with it. They have also repaired our Georgian garden wall. TJ Ferris Stonemasonry have undertaken repair work, at a competitive cost, on the Category A listed ancient monument of Coldingham Priory – treating 13th century stonework to reduce porosity and repairing Victorian weathered sandstone.

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.

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.
