Description
Cement Australia Gap Sand is a blend of graded fine sands and additives designed to lock all types of brick and block paving into place. It is swept into the joints after the pavers are laid.
It suits joints up to 3mm wide. It is not designed to function as a grout and is not cement based, so it does not stay permanently firm like mortar.
Use Gap Sand for joints only, and bed the pavers on a bedding sand or stone dust first. Cement Australia does not recommend it where pavers are continually exposed to moisture, such as around a pool.
