I am considering to lay indian sandstone on a ballast and cement base. Reading the main site it mentions the different bedding layers to use. I wonder if someone can kindly confirm if the bedding layer should be:
Sharp sand/cement 10:1 or 6:1
I understand that this should be mixed dry and the natural dampness from the sharp sand will fuse with the cement and cure over time. Or should a little water be added ?
Looking around the internet, I see some manufactures like Bradstone are suggesting building sand/cement 4:1.
Very confused and would appreciate some assistance from the wealth of experience on this magnificent site.
Thanks

I'm sure others will detail extensively, but, if I understand you right, you need to compact about 100/150mm substrate, if its a patio then one can argue as to thickness etc, but to be sure do the above, then lay the sandstone on wet pug, supported 100%, at about 30mm - 50mm thick. grout with Romex preferrably, or offdry pug, which is then struck with a trowel. Now that I've started on this, you also need to butter each paver before laying etc, SO - I'm sure Tony covers this extensively, if not on this website then buy the book, you won't regret it.

a ratio of 4:1 will do, pretty tacky (not a dry mix!)
no need to butter the stone up realy as wen u give then a tap down the morter will find its way up the joints anyway
also i would point it up with "geo-fix", u just brush it in dry an it sets like iron.
it also brings the colours out in the stone.

uh oh
think of your heart conditions lads
its hairdryer time
joe if you had read any of the site you would know that geofix has been totally and unquestionably condemned by all professional builders,i used it 6 times and it failed 6 times within a year
to paraphrase
its not worth a carrot
