This is the “old school” method, the standard for the industry that all other methods are compared to. In order to make a Type S masonry mortar one would proportion the materials into the mixer in this manner;

1 bag Portland Cement
½ bag Hydrated Lime
28 “Shovels” Masonry Sand
27-30 litres Clean Water

Or 5 parts sand one part cement, and plasticizer (eg bycol, or liquid detergent) (walls lower than 1,5 mts)
