The secret is to be careful not to have any air pockets in the bed and
use a bonding agent in the mortar. Use type S.
We did a lot of this and doing the whole thing at once is the easiest
in the long run. Bed the stone and grout up flush all at the same
time. Don't worry about getting mortar on the rocks, it is easy to get
off while it is still green. (first 24 hours or so depending on heat
and humidity). Start out doing a little patch to get a feel for it.
Lay out a bed of mud about an inch think and press the stones into it.
It helps if the stones are clean and a little wet, Then you rake the
excess mud off into the next spot you are working. Once the mud has
set up hard enough where things are stable, use a grout sponge to
remove the excess mud. I like the kind they have a Home Depot with the
scrubbie pad on one side. Don't go nuts cleaning them right now. The
next morning you can get mad at the spots you missed. Little flecks of
concrete in the stone can be blown out with a pressure cleaner months
later. The stone will look hazy for a while but that goes away after
you pressure clean them.
It just gets better after that.
