Hi Glen, and:welcome: I must echo Sir Ramics views, to be a real tiler takes years of experience. A course will give you a good start to understanding the basics of tiling. But tiling (real tiling) is a highly skilled trade. I would suggest you do your course, and then try and find a pro tiler in your area, who would let you tag along it may have to be unpaid, but you will then get an insight into the problems a real tiler has to deal with on a daily basis.
I do hope you don't take my post as being negative, but I do get a bit miffed when people think tiling is easy, I served a five year apprenticeship and have over forty years in the trade ( it is a TRADE) minimum now is three years, for NVQ . I know it is not easy to get qualified in this day and age, but I have seen the skill levels being diluted over the years.
I think it is time we had a reality check, tiling is, was, and always will be a skilled trade (sometimes bordering on art) when done properly and professionally, If you do decide That tiling is for you then I wish you the best of luck. But please don't expect to be a pro after a five day/five week course or even six months. It is not going to happen. There are some awsome tilers on this forum, some of them are finding things tough atm. So you may find yourself competing against them for work. I do wish you well, but as you may have gathered I am very passionate about my trade.
I hope I have not upset anyone by my opinion. It is just my opinion, and not the opinion of the forum.
