How is non hydraulic lime mortar/plaster/render made?

Our non-hydraulic Coarse Stuff lime mortar is made on site using our CHALK LIME PUTTY and a blend of grit sand and WAREHAM WASHED SAND. It is supplied as a ready mix, meaning it is easy to use straight from the bag.

  • The limestone and flint grit makes it ideal for flint work or pointing rubble stone as the combination maintains the white mortar colour with flecks of dark particles.
  • Available in 25kg bags. Or for larger orders, choose a half tonne bag, a tonne bag or a full pallet of 25kg bags.
  • Also ideal for backing coats of internal plasters or exterior render.

What is non hydraulic lime?

Non hydraulic lime is lime in its purest form. It sets in contact with air through a process of carbonation.  The slow setting process means non hydraulic lime remains softer and more breathable. It is good for internal plasterwork and for use on soft backgrounds such as cob, soft stone or friable material. There is more information on the differences between hydraulic and non hydraulic limes in our User Guide WHICH LIME?

Applying non hydraulic lime

Lime putty mortar has a long shelf life if kept within the airtight containers. If left for a period of time, it will start to settle and simply require 'knocking up' before use.

It is important that there is no risk of frost when applying non hydraulic lime mortars. Ice crystals forming within the lime mortar will greatly increase the time it will take the carbonisation process to take place. Using HESSIAN as an insulation barrier will protect from frost action and is vital during the winter months.

Teasing animal hair into the lime putty plaster just before use will increase the tensile strength of the plaster. The hair acts as a natural reinforcement and effective bonding key. We supply HORSE HAIR in 100g bundles. Or have a look at our user guide on ADDITIVES FOR LIME PLASTER.
