The spray texture works well, as mentioned above, there is over spray, and if this is a concern, take some card board, cut a hole larger then the area to be sprayed, and hold the cardboard a couple of inches away from the wall, then spray though the hole to the wall. This should limit the over spray.
I bought mine at ACE Hardware, Wildwood.
Hope this helps.
