Walls

Abstract

External walls may be of stone, flints, cob walling, brickwork, half-timber, weather-boarding, vertical tile hanging or shingles. Solid brickwork can be rendered externally with a lime and sand mix, or, more recently, with a cement, lime and sand mix. If trowelled smooth, whether marked in courses to simulate stone walling or left plain, the finish is usually called stucco. In smaller domestic work, pebbles are frequently incorporated in the second coat of rendering. The pebbles may be mixed in the second coat before it is applied, when the finish is called rough cast or wet dash finish. Alternatively, the pebbles may be pressed into the second coat after it has been applied and before it has set, this is pebble dash rendering.
