I've seen lots of threads on pebble dashing but no one so far has
actually said how its done.
What is the technique for applying the stones evenly, or is there a
device that will distribute them quickly and evenly.
+ how thick should the render be.

I'm doing an area at the front of my house that measures about 15 by
10 feet ( its not even that big because most of the area is window )
which at present has some nasty cladding on it that I want to get rid
of, left by the previous occupants... it's vile!!

Could anyone recommend any good websites if they can't explain ?
