naper i got fat before i got a machine lol, spunky you'd be doing more then 5m2 a day extra mate , 60m2 would be sprayed on and flattened in ready for trowling in about 25-30 mins, now i know that there is no way that i could lay it on that quick, and the plus side is that it is spraying freshly mixed material all the time rather then stuff that has been sitting around for 15mins
