For tiles of that size you need to be using powder adhesive. Tubbed adhesive dries by evaporation and with such large tiles it will take a long long time (if ever) to set.

Simple answer to your question - No it is not!

cheers for ure response

over 300 x 300 use powder gear every time.

Agreed

As the others have said, use a cement based (powder) adhesive for tiles over 300x300mm.
If you are going on to plasterboard then,
2 coats of neat BAL APD primer the fix with,
Single Part Flexible (white, if you are using a light coloured grout)
that will give you a 5hr pot life, so plenty of working time with it.

Nik, I've never heard of BAL Brown Bag

We do not recommend the use of PVA with tilling, which i think Unibond is.
I'm not sure what you can do about that now though. Maybe Gaz or Danny will have an idea on that?

As for your render, as long as it is sound, just prime it with BAL APD.
If it needs patching, use BAL Quickset Render. That can be tiled on after 2hrs if need be.

Possibly, or maybe the Natural Stone adhesive, which is bagged for Topps.

If it is Goldstar, you'll need to ad AD1 for the plasterboard area.
