Masonry Mortar

 Masonry mortar is composed of one or more cementitious materials, clean well-graded masonry sand,

 and sufficient water to produce a plastic, workable mixture. 

 Mortar for masonry joins units into an integral structure with predictable performance properties. In

 addition, it:

• Creates a tight seal between units against the entry of air
  and moisture.
• Bonds with joint reinforcement, metal ties, and anchor bolts,
  if any, so that they perform integrally with the masonry.
• Provides an architectural quality to exposed masonry structures through color contrasts or shadow lines from various joint-tooling procedures.
• Compensates for size variations in the units by providing
  a bed to accommodate dimensional tolerances of units.
