More formally known as a Class II mortar, this is a good all-round mortar for buttering and pointing flags, laying brickwork and rigid block pavements, and everyday patching/repair jobs. Properties of masonry mortar related to its durability include: Since Masonry Cement color is laboratory controlled and Masonry Cement offers the simplicity of the one bag system of batching, it is easier to achieve consistent color cement for a prefect appearance in the finished job. In practice, Class II mortars are used for most applications. Type M is used for below grade load-bearing masonry work and for chimneys and brick manholes. Table 1 is a general guide for selection of mortar type. The compressive strength of prescribed mortars will vary according to a number of factors, particularly the type of sand that is used, but historically there has been an empirical relationaship which has been used in arriving at Table 1. Type N mortar mix has a medium compressive strength and it is composed of 1 part Portland cement, 1 part lime, and 6 parts sand. Do not use lime with masonry cement.
