Stone supplier has recommended fitting their 20mm (900x600) stone outside on a 50mm sand/cement bed over hardcore. Sbr slurry on the back to reduce staining.
Anyone believe this is a correct method of installation or what are your alternatives.
Your thoughts please.
I did one last year in the summer, same size. Is it Mandarin stone? Did it like @JulianSidney said in stretches. What have they recommended for grout?

It'll be a dry mix wetted!
It was Mandarin Stone I laid, hammered finish limestone, 5mm joints laid into 24:1 sharp sand and cement, semi dry with SBR slurry done in stretches. The grout was hand made soft washed sand, snowcrete and yellow colouring. I sprinkled water into the joints then soft brushed the dry mix into joints, then compacted with trowel. The mix pulls the water up then after a time pointed and brushed away excess.

Forgot to say regards the hardcore, I got the contractors to roll it tight, then put in a 1 inch bed of sharp sand raked and rolled tight then dampened and used building paper!

I would do a much stronger mix for the sand and cement 10 or 8 : 1

Served half my time with pile of sharp sand, bags of cement, mixing board, barrel of water and a shovel for Toffolo Jackson. Don't know how many tons per day me and another apprentice mixed and carried. But tradesmen were scary guys back in that days and if they said 24 shovels to 1 bag cement guess what we mixed? Stuck with me all my life and never mess with it and never let me down :)

Do you know why it was spec'd that way John?
Because I wasn't happy with the way the contractor expected the job to be done so he asked the stone supplier how they recommended it be done!
That's what he came back with so now I'am thinking do they want it fixed by a landscape gardener or a tiler - so I may have to get my wellies on and get a rake or instead go and do a few nice little victorian jobs.

Just an update - this is how it turned out - as per suppliers specification.

That's when bags of cement weighed 1 cwt/ 50kilos. So l recon that's a mix ratio of about 1 to 6. Once worked on a site, where Toffolo Jackson, where fixing terrazzo wall and floor tiles, aye the apprentices, had to graft. Probability back in about 1970 ish.
Was working for a builder. On burnt field road in those days, where Toffolo Jackson also operated from. ( oh, the old days).
