Description
Cornish Lime have been manufacturing Lime Putty since 1994 and we take great pride in the quality having earned a reputation within the industry as one of the leading manufacturers in the UK. Our Lime Putty is made using high calcium quicklime from Buxton, Derbyshire in the traditional method of storing in pits after slaking (adding to water). Our putty is matured for a guaranteed minimum period of four months and will have an approximate bulk density (RBD) of 1350kg/m3. It is important when ordering lime based materials to know the density of the lime putty; putty with a lower density will have a higher water content with less available lime. Therefore, additional lime could need to be added into the mortar.
Lime Putty in mortar, render and plaster: traditionally, the main use for Lime putty would have been in renders and plasters having been allowed to mature for a period of several months, or sufficient time to allow all the quicklime in the form of calcium oxide to fully convert to calcium hydroxide. Whereas traditional building mortars were made from quicklime and sand mixed together in a process we today call Hot Mixed Lime this was a simpler process which yielded a lime rich mix ideal for most aspects of masonry, and we believe that if the mason’s or bricklayers were to have taken the putty it would have highly likely resulted in distress of some form at the site.
However, Lime Putty today is used for all aspects of construction, although some are clearly not appropriate for this material as its virtue can sometimes be its downfall, although there is no doubt that it produces the most vapour permeable of lime mortars. Cornish Lime as one of the largest producers of Lime Putty in the UK recognise these issues and remain at our customers’ disposal to assist in the selection of the most appropriate materials for your project.

Used In Conjunction With
Putty when mixed with Sand, usually at a mix ratio of 1:3 or 2:5 will make a lime mortar. Hair, Fibres or Pozzolans can be added to the mix to modify certain characteristics of the mortar.

Application
The most important thing to consider when working with a Putty based mortar, is how the mortar will cure. Unlike NHL's, Putty mortars need to be well protected from extreme heat, cold or moisture while they carbonate. Read out guide to Curing Mortars before working with Putty Mortars unless you know what your doing.
