For information on how to use both Hydraulic and Ordinary Lime Mortars, please download the Mortars Best Practise Guide PDF at the bottom of this page.
Pre-Mixed Lime Mortar is usually made by mixing lime putty with sand; it is suitable for both building and pointing. The mortar is supplied ready-to-use but will require 'knocking-up' prior to use - ideally using a mortar mill. A range of standard mortars can be made using Singleton Birch limes, but should you wish to match an existing mortar, we could advise on an appropriate mix by analysing a sample of the original mortar.
Hot Lime Mortar (only suitable for building) is produced by adding Quicklime (Lump Lime) to damp sand. It has small lumps of lime in it, which can often be seen in old mortars. It is good for general building but should not be used for plastering/rendering or pointing.
