Wet masonry mix is extremely caustic, so protect your hands with rubber gloves. Plan to use about 1 gallon of ready-mix for each 12-inch stone. For many stones, it's often cheaper to use this recipe: 3 parts masonry sand, 1 part Portland cement type 1, and approximately 1 part water. Blend dry ingredients thoroughly until mixture is one color. Make a well in the center of dry mixture. Pour water in well; mix until it is the consistency of custard. Use immediately.
