Never had a mix set in less than an hour myself .. Would presume most plasterer can get a bag on ,laid in and finished off within that time tbh, as long as they haven't taken on to big an area than they can cope with.. On domestics especially most don't mix up more than a bag or two for putting gauge on.That's the beauty of pva though, you always know how a wall/ceiling will behave by the drying time of it.
He kopped out simple as that.
