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.

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.

I’ve known of Tom Ferris and his work for some time. I have used him for private work on my property – which this review covers – but as a Trustee of a Grade A heritage property in the Borders, I have recommended and used him for work on that elevated level of craftsmanship. I have also seen his work on at least three other Grade A properties. I regularly recommend him to Boards of Trustees and private individuals who own heritage properties. He worked for me on a private project, creating a curved wall as part of a new remodelling of an area of my property. He produced a result that is frequently praised by those who see it for the first time.

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.

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.

I have commissioned both small and large stonework projects from the firm and I have always been impressed by the quality of the work. I would not hesitate to use their services again.
