Pebble dash is a hard-wearing finish for outside walls. A sand and cement scratch coat goes on first, then a top coat, and while that coat is still wet, small stones are thrown at it so they bed into the surface. Spar dash and Canterbury dash use different stones, for a different colour and texture.
Thank you for reading this post, don't forget to subscribe!Old pebble dash can come away in patches when the render behind it fails. Small areas can be patched, but new stone rarely matches old dash exactly, so a whole wall is sometimes redone to keep it even. Tyrolean is a different textured finish, flicked onto the wall by a hand-turned machine.
