I'm not naive, I am simply making sure I know what I'm doing and specifically with the additives, the kitchen wall tiles are still up a year on and they look great, to be honest it was like adult lego, stick them and space them, I found it quite straight forward so maybe you could explain why a floor is so much different to walls?Granty, your incredibly naive about the job in hand! But i do hope it works out for you.
I had to underpin parts of the wall tiles but to me tiling a floor so long as you have advice from a DIY tiling forum or two would be hard to go wrong, like I said I appreciate many here are in the trade but i'm sure plenty of people out there are confident in their own ability and that includes not starting before you are sure you know what is what.
