Should I trowel the wall and backbutter the tiles

[bluevin123]

Hi,

Laying 600x300 Copper honed slate tommorow which is 12mm thick,as well as troweling the wall, should I backbutter the tiles as well?
Cheers,
Vin.

Short answer, Yes mate

Without a shadow of a doubt

You really need to get a good buttering on the back of the tile as well as using a 8 or 10mm serator

What background are you fixing to for weight purposes?

Im fixing them to 12mm Hardiebacker board which I put up last week, they can take up to 45kg with a good wall stud.
Cheers,
Vinnie.

Make sure your adhesive you are using is suitable for the bed depth..

Yeah I will Dave,

Gonna use powdered rapid set.

Keraflex would be my sticky of choice

If you end up bedding over 6mm depth regulary, then switch to a thick bed adhesive..but you should be ok if your prepped right..
