- A. Install units true, plumb, and level, in accordance with
- manufacturer's installation instructions and shop
- drawings.
-
- B. Install units using experienced and qualified stone
- masons or tile setters.
-
- C. Prepare substrates to receive units as indicated in
- manufacturer's instructions.
- 1. Clean substrates of oil, paint, dust, and debris.
- 2. Make surface smooth, level, sound, and capable of
- permanent adhesion.
-
- D. Units to be set into adjacent finish (rather than mounted
- on surface): If units are not available at the time the
- finish is to be installed, install a plug (a piece of
- foamboard or wood 1/2 inch (13 mm) larger than the unit
- to be installed) in the unit's location. After finish is
- complete, remove plug and complete unit installation.
-
- E. On Concrete, Masonry, and Portland Cement Stucco: Set
- units with mortar:
- 1. Drench units not already thoroughly wet with clear
- potable water and remove excess water prior to
- setting.
- 2. Place anchor pins firmly in place and fill holes with
- mortar.
- 3. Set each piece in full bed of mortar (100 percent
- coverage) with vertical joints and holes in substrate
- completely filled.
-
- F. On Exterior Insulation and Finish System: Use EIFS
- manufacturer's adhesive to attach units to insulation
- board.
- 1. Use anchor pins long enough to penetrate through
- insulation board into substrate.
- 2. Place anchors firmly in place and fill anchor holes
- with adhesive.
-
- G. On Interior Gypsum Board and Plaster: Attach units with
- adhesive, 100 percent coverage; set anchor pins into
- holes in substrate.
-
- H. Maintain maximum 1/4 inch (6 mm) joint between units.
-
- I. If units will not rest on permanent mechanically-anchored
- supports, provide temporary vertical support prior to
- setting.
-
- J. After setting, brace each unit with a diagonal support
- pressing unit into substrate.
-
- K. Do not remove temporary supports until after full cure of
- setting material.
- NOTE ** Delete any of the following joint treatment
- paragraphs that are not applicable. Coordinate
- with the materials specified in PART 2.
-
- L. Seal joints between units and between units and adjacent
- materials.
-
- M. Point joints between units and seal junction between
- units and adjacent materials.
-
- 3.3 CLEANING AND REPAIR
-
- A. Immediately after setting, clean face of each unit to
- remove splashed mortar and mortar smears.
-
- B. Protect units from splashing mortar and damage due to
- other work. Immediately remove foreign matter splashed
- or rubbed on units.
-
- C. Repair chipped and damaged units, using skilled mechanics
- and manufacturer-provided patching materials and

- imperfections show other than normal, minimal color
- variations when viewed with the unaided eye under good
- typical lighting.
-
- D. Clean units only when necessary, by scrubbing with a
- bristle fiber brush and specified cleaner. Do not use
- acid or prepared cleaners unless approved by
- manufacturer. Rinse thoroughly with clean running water.
