Jointing and Pointing for Stone Paving

Use a dry-ish building sand, plastering sand or, if so desired, a Kiln Dried Jointing sand. Some installers like to use a coarser or sharp sand, but this can result in a rough-looking finish when used for dry grouting. A 3:1 ratio of sand and cement are mixed without the addition of ANY water. None. At all.
