Part 3 Execution

3.0 Preparation

    .1 Open Stud: Install paperbacked metal lath to studs using galvanized nails or staples which penetrate a minimum of 1" and 4" on center.  Apply  3/8" to ½" scratch coat and allow to dry for 48 hours.  Wrap weather resistant barrier and metal lath a minimum of 16" around all outside and inside corners.

    .2 Sheathed Surfaces: Install one layer of weather resistant barrier with lap joints 4 inch shingle fashion.  Apply code approved metal lath, attach with galvanized nails or staples which penetrate a minimum of 1".  Apply 6 inches on center vertically and 6 inches on centers horizontally.  Wrap weather resistant barrier and metal lath a minimum of 16" around all outside and inside corners.

    .3 Concrete and Masonry Surfaces, New, Clean and Untreated.  Examine newly poured concrete closely to ensure that its finished surface contains no releasing agents.  If it does contain form oil or release agents, etch surface with a muriatic acid, rinse and or score with a wire brush, or use high pressure water or sandblasting to remove.

    .4 Existing Concrete and Masonry Surfaces: If required remove paint, coatings, sealers, dirt.

 

3.1 Mortar Mixing

    .1 Thoroughly mix  mortar ingredients in quantities needed for immediate use in accordance with ASTM C 270, Type N.

    .2 do not use anti-freeze compounds to lower the freezing point of mortar.

 

3.2 Application.

    .1 Apply 3/8" to ½" of mortar to (lath) (dampened masonry, stucco, or concrete surface), covering roughly 10 square feet at one time.  Butter the back of each stone unit completely with mortar, then press the units firmly into position in soft mortar bed.  Wiggle and apply slight pressure to unit to ensure firm bonding causing mortar to extrude slightly around the edges of the units.  Place units with uniform mortar joints.  Stone joints should not be over 1/2'" inch in width.  Remove excess mortar, do not allow mortar to set up on face of units.  Rake and tool joint before mortar has set.  Clean and finish joints.
