Discuss 20mm stone paviours outside. in the Specialist Tile -Stone, Porcelain, Glass area at TilersForums. The USA and UK Tiling Forum (Also now Aus, Canada, ROI, and more)
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 used to put the slurry mix on the 'semi dry' (just holds together when gripped in the hand) sand and cement.
lay sand and cement 20mm high and tap stone down to bed.
nobody brave enough to give an old timer advice, me I'm just being a rebel this week
If you could figure out what it says the old....

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!
Best part of this one - don't know !
Possibly a Dijon limestone.
I can talk to you about Dijon mustard if that's any help?

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.
Do you know why it was spec'd that way John?

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
