All lime mortars, whether used for pointing, render or plaster act as a poultice, drawing moisture and harmful salts away from the fabric of the building and leaving it sound, dry and pleasant to live in.

Rough cast render, known in Scotland as harling, is made with a coarse sand and the top coat, as its name suggests, is thrown on fast and loose.

This casting process produces a vacuum which improves adhesion, and its rough surface gives walls the optimum capacity to breathe and withstand the Uk’s variable weather. It is usually finished with a softly coloured lime wash and even decorated with a little stamp work or pargetting.

Flat work gives a tighter surface which can also be finished with a lime wash or used as a ground for all manner of decorative work, ensuring the health and longevity of a building, and adding its unique aesthetic.

The breathability of lime mortars makes them essential to the proper repair and conservation of period buildings while bringing their unique softness and elegance to contemporary ones.
