Hi Colin
I think APM is saying that 4 days is just not enough in this game and he would be right. If you are coming into this game cold you need to do a 4 week course minimum, if you already know a thing or 2 i would still recomend a 4 weeker but if you know a fair bit already then you might get away with a 2 weeker.
The one weekers are designed for the DIY game, the centres won't tell you this mate but please take my advice ONE WEEK IS NOT ENOUGH!!! you have to remember this is a skilled trade and many of the tilers on here done aprentiships and years of college to learn this game.... i think it's almost an insult to them that these centres claim to turn you into a pro in a week!!!
I done the 4 weeker at PTS and i still have miles to go before i'm anywhere near as good as some of the pro's. But please don't let what i say put you off, it's a great game and there is plenty of job satistfaction and money to be and it can offer a great career change, but if you want a proper head start into it you must do the 4 weeker or at least 2 weeks with the intention to go back and do a further 2 weeks.
If you are in the midlands type area i hear that Chase tiling acadamy are supposed to be good (if i'm right i think that is where APM started) he'll probably fill you in on that. If your up north there is a new centre opened up in yorkshire which is supposed to be really good (can't think of the name but will try to find it for you) if your down south you would do ok with PTS.
I hope some of this helps mate, keep us posted
