Mix the Mortar
The mortar mix is two parts sand to one part mortar. Mix the sand and mortar first, then add the bonding agent, and finally add water. Follow the manufacturer's directions when mixing mortar, but add enough water to achieve the proper consistency so that the mix is neither too dry nor too soupy. Let the mix sit for five minutes before using it to ensure that it's properly coagulated. When mixing mortar, it's best to pull the bulk of the ingredients to one side in the wheelbarrow or mixing container. This will save you some strokes, make mixing easier and lighten your workload.
