I’m adding “veneer” stone to the house I am building, and would like any advice on what mixture of portland, type “s”or whatever type of martar to use for both the scratch and stone setting layers..
>the stone will be 3/4″-1″ thick, and will have an expanded metal lath under the scratch coat.It will be going over concrete as well as building papered OSB. Thanks for your help…

Most veneer stone has their own mixture, depending on the manufacturer, so please contact them for details to avoid warranty problems.
Assuming you have no directions, I would use plain old stucco brown coat for the base over diamond lathe, and a 5-1-1 mix with the final set.
Good Luck!

ok..i admit my ignorance...5-1-1?
please elucidate.THANKS!!!!
(and if you would....what are the components of brown stucco?)

Have you read up on mortar/masonry at all? The reason I ask is because of your Q regarding 5-1-1. I would recommend you head on down to the library and read a basic book (time-life series, etc) on mortar. There are techniques involved in batch mixing, strength considerations regarding the amount of water to add, and "1000 word" pictures that will clarify things to you. It should help immensely.
Contact the distributor regarding installation. There are usually VERY SPECIFIC instructions on installation considerations. While most use type S, your product may specify something different.
Technique-wise, depending on the surface you are veneering, you may want to work top-to-bottom. Many pro's install it that way to minimize drips on the completed face below. Also, lay out your veneer on the ground in a pleasing arrangement so that when your ready to apply, you're not searching for that "perfect" piece.
Good luck.

Is there any special consideration for concrete that is "aged". I want to apply a veneer to hide the poor form work on a retaining wall as well as the exposed basement wall. The foundation is 16 years old and in great shape. I just dont care for the look of concrete.
Is there a preferred method for attaching lathe?

Typically, no. As long as it has never been sealed, sealing is the big no-no. If the surface is clean, no mineral buildup, no crumbling, it should be okay.
If you have a large area to lathe, you may want to shoot the nails to attach, you could rent for a half-day. It would be an awful lot of concrete nails to drive by hand. If you do, make sure you use a soft hammer.
