Indian sandstone - "stick" to concrete block bed?"

[Chazman88]

Hi,

I've got a plan for a DIY project involving a patio enclosed by a raised flower bed. Current plan is to build the raised bed out of 100mm concrete block but I would like the raised bed to be finished in the same sandstone as the patio surface.

Long story short, Ive ended up with a joblot of "Premiastone" 25mm sandstone in 900x600 slabs which I want to use.

What is the correct way to stick/bond/clad these sandstone slabs to my concrete block raised plant bed?

Ive bought Tony's book and its answered a load oy my questions but I still have a million more, im sure this is the first of many for these forums!

Thanks

Cool, thanks.

So a quick bit of research online looks like Ardex S 27 could be a suitable product to use.

Any others that you could recommend me looking at?

The Ardex is fine, but also look at what BAL have - they tend to be a bit more competitive on price.
