Scratch Coat over stone foundation

Greetings All,
I looking for a little help. Recently we have been having a problem with ants. My DW pointed out that the infestation ocurred shortly after my 4 year old son (he loves demolition) pulled off the existing concrete scratch coat covering the above grade (about 2 feet) portion of the stone foundation. The house was built in 1912 with a stucco finish. We are located in Southern Westchester County in New York State.
We hope that if we eliminate the ants entry through the stone foundation, we will have won a major battle and hastened their doom.
What type of concrete should I use?
Any prep work required?
What kind of trowel?
Thanks,
JW

Greetings whale,
This post, in response to your question, will bump the thread through the 'recent discussion' listing again.
Perhaps it will catch someone's attention that can help you with advice.
Cheers
"The old Quaker Meeting house is almost 300 years old and as my sawzall made its way into the pegged ancient wood, a smell emerged that told me about dried, cracked things. The ancient Quakers sitting in the well worn pocket of their silence on the darkened pine benches were whispering something to me across the years. Something about why I was here, why we're here. Lord but it was hot. I reached in to clear anything out of what was the sill, nothing but the hardened mud, lime and sand mortar, dust and shadows." -- Jer
Whale, this is what I would do, have done, got paid,customer
satisfied! bottom line.I would use type "S"
mortar mix to make a parge coat finish,that would be
good for about a 3/4" thick or less coating on your rock
wall , if not thick enough, build it up in 1/2" coats with
the first being the scratch coat. I use a plastisizer in my mix
to help with workablity and to give the mortar some weatherproofing.
I use a universal mix of 11 squarepoint shovelfuls of sand to a half
bag of mortar, I get the plastisizer from -Quickpoint mortar gun co.-
they sell it as their pump aid.I also use just a plastering trowell
or a pool trowel a 4X10 size fits my hand nicely ,others may get
real technical but this is what works for me.
also dampen the wall before applying the mud, and remove any
loose dust, mortar chuncks , ant carcuses what have ya from the area. D.W.
