USES
Used in normal residential and non-residential applications such as veneer, curtain and partial walls, chimneys and back up walls.
Exterior and interior masonry work:
Each 66lb (30kg) of Masonry Cement mixed with 3cuft of sand will produce 3cuft mortar.
Avoid working in extreme weather conditions. Have materials required on hand: clean water, sand (2 ¼ -3cuft loose damp Masonry Sand), watertight mechanical mixer, measuring pots, trowel, mortar board, etc.
Mix ½ water and ½ sand required to 1 bag Masonry Cement Type N followed by the remaining amount of sand and enough water to bring mix to desired consistency. Mortar should be mixed for at least 5 minutes once all ingredients are in the mixer. Each batch should be the same consistency.
When mixed with sand that meets the requirements of specifications ASTM C-144, Type N Masonry Cement produces mortar that exceeds ASTM C-270 specification for mortar which requires a minimum average 28-day compressive strength of 750psi and 75% minimum water retention.
