Non-hydraulic lime putty ready-mixed mortars produced from 6 month mature mortar grade Chalk lime putty mixed with sands and stone-dusts normally at a ratio of 1:2.5 or 1:3 by volume. Standard + Special + Matching mixes available.
Lime putty mortars are supplied ready-mixed and in a ‘ready-for-use’ consistency but stiffen during transit or storage. Workability can be restored by re-mixing in mortar mixer or by whisking.
See our Technical Advices here and The Use of Lime Putty Bedding & Pointing Mortars.
Lime Putty mortar is an environmentally sustainable product.
For bedding and pointing stone and brick where a traditional soft, porous, permeable mortar is appropriate. Do not use below a temperature of 5°C or above 25°C. Do not use if there is risk of frost.
Bedding: c.800 – 1000 bricks/ tonne (225mm brickwork), 4m2/ tonne (450mm rubble stonework) Pointing: 100m2/ tonne (brickwork), 40m2/ tonne (random rubble stonework)
Unlimited. Matures with age. Lime putty mortars stiffen during storage, but can be plasticised without the addition of water by thorough re-mixing.
Cream coloured mortar. Colour can be matched and adjusted with the addition of stone dust.
This ‘carbonation’ is a slow process and control of the drying and curing process by ‘tending’ and protecting is crucial to success and long-term performance. Protections are essential.
Tradesmen familiar with the use of lime putty mortar, and with experience of its successful use should be employed. Non-hydraulic lime mortars do not perform as modern hydraulic lime and cement, and set only by reaction with atmospheric carbon dioxide in the presence of moisture. This ‘carbonation’ is a slow process and control of the drying and curing process by ‘tending’ and protecting is crucial to success and long-term performance. Protections are essential. Do not use below a temperature of 5°C or above 25°C. Do not use if there is risk of frost.
