Installation + Cleaning

CMU Installation

Jandris Architectural masonry units should be installed consistent with the best masonry practices. Always handle units with care using extra caution not to chip corners and edges. Install units in the wall true, plumb and level, taking care not to smear mortar on faces.  Clean as you go.

Leave extruded wet mortar joints set until semi-dry to the touch, then tool joints as specified. Let set, brush dry being careful not to smear mortar. Be sure to cover the top of all walls every night as to prevent moisture from getting inside the wall.
