I'm planning to build a split face granite stone wall around my garage. Can anyone give me the ratio (shovels of sand, cement and/or mortar) to add for the mix. It's been years since I laid up a stone wall and don't remember it for sure.
Also, any tips on cracking a stone, such as how to read the grain would be appreciated.

Thanks, Howard

Ingredients
You can buy ready to mix mortar in a bag or mix the constituents on your own. I prefer to mix my own. When you mix your own, you can control the ratio of them. Pictured above left are the 3 main components. From L to R, Portland cement, Masonry cement and Sand. I prefer a mixing ratio of 1:0.5:3. Type S cements are stronger than type N and should be chosen. Soft sand is also desired over gritty sand when doing stone work

Masonry cement provides a strong bond as well as being able to deal with freezing and thawing. Portland cement supplies flexural strength and adhesion

Sorry didn't see the link above..

If you plan to use sand and portland cement... the standard above-ground ratio is: 5 parts sand to 1 part portland cement. If you plan to add lime to inhibit mortar shrinkage as it dries... add the lime at the same ratio as the cement: 5:1:1.

I would use pre-mixed mortar mix, though... it usually has a "plastic" ingredient that helps to prevent shrinkage and cracking.

Thanks to all on the reply for the mixture ratio. I'll be starting it in the next couple weeks and appreciate the help.
