Sand Cement Dry Pack
Dry pack mortar, which is also called deck mud or floor mud, is a mixture of sand, cement, and water. It is used to repair small spots, creating thick bed mortar for tile and brick placement, and bed shower installation. The proportion of the mixture is one part of cement to four part of sand, and adequate water to produce mortar that stick together when it is molded into a ball with hands as illustrated in Fig.1
