Large floor tiles - what trowel

[acaciaguy]

Hello everyone. I’m fitting some large floor tiles next week. 1000 x 1000 mm over electric underfloor heating. These are the largest tiles I have fitted before. My plan is to use a 20 x 10 mm round notched solid bed trowel along with back buttering. I believe this is a good approach but any advice greatly appreciated.

I'd go for a 12x12 and trowel the backs with a 6mm notch.
Are you using a uncoupling membrane? And clips?

Many thanks. Using clips. Not using a membrane. Concrete floor, insulation board , ufh then porc tiles

Hope you have help
I take it they are not thin (6mm) tiles

 

[acaciaguy]

No they are 12 mm thick. I do have help

You will need it, it's a two-man lift for one of them😱

I probably the weediest bloke on this forum and I did some 1000 x1000 on my own ( mainly because nobody likes me ) and it wasn't to bad apart from two awkward lifts . I just drop in one side then lower towards myself
