Even though i use a plazzi myself, I have seen some shocking applications with spats, plazzis etc. We did a block of flats last year and another gang were doing a floor below us. I popped down for a little nose and watched them lay on. one lad was chucking it on so rough you wouldnt believe, and another following flattening with a spat. Gloating at their coverage (probably no more than a dozen metres more than us a day, both 2 and 1 teams) read someone on here say "first coat flat, second coat flatter" thats the way IMO
