Hi Folks, hope all's well out there.

I've just bought a new house and inherited a pallet of tiles which I intend to lay over the grey brick drive at the end of my garden. pic attached

Can anyone suggest a good adhesive (sand/cement) mix for this task?

The tiles are terracotta and I'll be putting in about a half inch of grout. It's about 50 square metres so want to have minimum hassle.

Any pointers towards quantities for this job would also be appreciated
