Exterior RenderLath and Plaster – Pointing and Mortar Repairs – Lime Wash – Courtyards and Garden Rooms

All lime mortar, whether it is used for pointing, render or plaster, acts 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 produces a vacuum which improves adhesion, and its rough surface gives walls the optimum capacity to breathe. It can be left as it is, finished with a softly coloured lime wash and even decorated with a little stamp work.

Flat work gives a tighter surface which can be finished with a lime wash or used as a ground for decorative work.
