it was at alltec brendan, and run by the 2 guys that own tilemaster, alex rimmer and martin shelley, but it wasnt a tile master course it was a stone cleaning and mild restoration/repair course. very well structured, took loads from it even though i know a lot from previous courses,
some great marketing tips, crack repair, acid etching removal from a good finish and a premium finish, that was an eye opener.
definitely worth the investment.
would highly recommend to newbies and intermediates like my self.
