I do quite a few of these, make sure the muck is well dry and use no chemicals unless you really have to, Get a bloke to sort out the boards and caddy the hoses and you'll whizz through it. I did one that had a swimming pool, bar, cinema, wine cellar, gym, sauna, hot tub and utility room in the basement and it was all face brickwork - It took a whole day but the outside only took 3/4 of a day
