Womersleys Mature Lime Putty

Description:

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.
