First spotted besmirching properties in the 1920s, the art of the pebbledash is where a conbination of Portland cement and small washed stones are rendered all over the external walls of a house. Apparently an attempt to mimic the textured roughcast look pioneered by William Morris' Arts and Crafts Movement. Pebbledashing nigh on impossible to remove, so is still seen everywhere (including the house I rent at the moment).

Pebbledash people is one of the terms used to describe a person who fits into a certain social stereotype in the UK
