I have a breeze block wall which is rendered and want to fix some sandstone slabs to it. Not sure on best way to fix them was thinking of using grip fix or is there a product for this.
The sandstone slabs I am laying on the patio are smooth cut and come in 3 colours I wish to continue the slabs in another colour up a wall 1mtr x 5mtr which then also becomes a garden seat and also face the side of the steps
could use epoxy mortar, but depends on what you want as a finish, what are your walls sealed with, and are there any dpc problems steps could be fa\ced using any appropriate mortar jointing

If I understand correctly, you plan to use the paving as a cladding for the wall. If so, then you need a very strong adhesive, either epoxy or SBR/Ronafix, to be able to carry the weight of the individual flagstones, and I'd be tempted to use a back-up fixing, summat like masonry nails/anchor bolts set into the joints to halp carry the flags and transfer the load directly to the wall.
