This chimney was recently harled in Roundtower Lime Mortars. Harling is a Scottish name for what is often called wet dash or rough cast. This is probably the most traditional finish that is still common today.

Bashing a freshly lime pointed rubble stone wall in preparation for lime plastering. This is carried out at the end of the day as the pointing is picking up, the action compacts the mortar and exposes the aggregate.

We installed in Cor Castle Unipipe underfloor heating pipes in limecrete under a natural stone floor powered with geo thermal heat pumps 20 years ago resulting in a lovely warm stone floor ever since!

gypsum plasterboard and other non porous backgrounds.

Lime has been the primary binder used in mortars and plasters for thousands of years and the vast majority of all buildings constructed before 1900 made use of lime. Despite this, in many cases today lime is ignored, so why Lime?
