What is pebble dash render / pebbledashing?

Castle Heights Building & Maintenance answered the question "What is pebble dash render / pebbledashing?"

Pebbledashing or as it’s known in Scotland - rough casting, is the process of applying a sand and cement rendered coating to a wall and before it drys taking small stones or aggregate chippings and throwing (dashing or casting) them at the wet render to slightly embed the stone in the surface so that it sticks to it. It is done to achieve a hard wearing weather shielding and the use of a coloured aggregate can achieve a more desirable aesthetic than flat painted render alone. Hope this helps
