Guys, i posted a while ago about pebble dashing my block outbuilding...i failed miserably.....so now i am looking for some kind of exterior artex type material to cover the block work, i scarped off the pebbles and just rendered it smooth, well, smoothish....what can i put on it, and can i get it from a local builders merchant..i could try textured paint, but i dont think that will be thick enough....please help
