Description

Non-hydraulic superfine lime putty slaked from fine grade quicklime. The putty is matured for a minimum of 12 months. Two superfine grade putty types are available – a pure white Buxton putty and a cream coloured Singleton Birch putty. Singleton Birch mortar grade ‘Chalk Lime Putty’ also available (RJ 1.08). 

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. Do not use in temperatures below 5°C or above 25°C. Protect from frost.

Environmental Considerations

Lime Putty is an environmentally sustainable product made from natural ingredients. It contains no VOCs and no petrochemical products.

Usage/Purpose

Used in fine finish top-coat lime plasters when it is mixed with a fine sand normally at 1:1 or 3:2, and for lime/gypsum blend finish plasters. Superfine grade putty is used in the manufacture of Sheltercoats (RJ 3.07) and can be diluted with water and used as an internal limewash. Superfine lime putty is used in Conservation mortars (RJ 2.07) and ‘fine conservation’ generally.

Shelf Life

Matures and improves with age when kept in sealed containers protect from frost.

Colour

Mortar colour is determined by the sand or aggregate mixed with the putty.

Application

Tradesmen familiar with the use of lime putty, and with experience of its successful use should be employed. Accurate volumetric site mixing is essential. Non-hydraulic limes do not perform as gypsum plaster or modern hydraulic lime. Non-hydraulic lime sets only by reaction with atmospheric carbon dioxide in the presence of moisture. This ‘carbonation’ is a slow process and control of the drying and setting process by ‘tending’ and protecting is crucial to success and long term performance. Protections are essential. Do not use in temperatures below 5°C or above 25°C. Protect from frost.
