I would suggest you stick a two component mortar (kerabond T/keraply over the counter or Granirapid or keraflex super but this are special order)
I also would suggest you verify that the wall is capable of supporting the weight. Many of these products can be heavy.

Thanks Jason.

This is not going on the counter. This is for the wall. The wall is 16ga steel studs with durock cement board screwed on. The stone is 3/4in thick ledger stone panels. I am trying to find Keraflex Super, but I cannot even find a way to order it from any Mapei supplier.

So Kerabond T with Keraply would be suitable in a freezing climate? Do I simply mix Keraply instead of water? How much per 50lb bag of Kerabond T?

Mike,
Yes the latex additive is used instead of water...its 1.8 gallons per 50lbs...
MIXING
Before product use, take appropriate safety precautions.
Refer to the Safety Data Sheet for details.
1. Into a clean mixing container, pour about 1.8 U.S. gals.
(6.81 L) of Keraply for the desired consistency.
2. While slowly mixing, gradually add 50 lbs. (22.7 kg)
of a dry-set mortar
3. Use a low-speed mixing drill (at about 300 rpm), with an
angled cross-blade mixer or auger mixer. Mix thoroughly
until mixture becomes a smooth, homogenous, lump-free
paste. Avoid prolonged mixing.
4. Let the mixture stand (“slake”) for 5 minutes.
5. Remix.

Our data sheet is here.

Thanks Jason.

I keep changing my mind on what kind of veneer to use. Right now I am leaning towards cultured ledger stone, thinking slate might delaminate from constant freeze/thawing (see below for the cultured stone I am thinking of using). I have seen it on slate pavers. Not so much on outdoor siding, but that stuff is usually 1-1.5in thick. I can only fit a max of .75. Most of that stuff says indoor/outdoor but you only really see it indoors. Other natural stones (not slates) are crazy expensive for this project (15 to 25 bucks sq ft).

Can someone comment on the difference between using the Mapei products as described by Jason above, and using a type N or S mortar mix such as :https://www.lowes.com/pd/QUIKRETE-Ve...ar-Mix/3055465 ?

I never really understood this. I do not need any grout joints and This is on CBU, I will not use any lath. Also, outdoor use in Wisconsin.

The instructions on the stone call for a type N or S, but I am pretty sure the Mapei mortar with additive is superior. I suspect it is not called for because it is too expensive when applying the stone to an entire home, and is not meant for such a thick application on lath along with scratch coat, bond coat which is done when applying to a home with plywood sheathing.

This is just what I suspect but do not have any data or specific knowledge to back that up.

Thanks yet again.

also, while you guys are figuring out the above question, what notched trowel would you recommend? I have .25x.25x.25 and .25x.375x.25 and .5x.5x.5.

The trowel type depends on the product used, and whatever is necessary to get as close to 100% coverage as possible...
