<br />PROJECT NO. 21-1011
<br />BUILDING DEPARTMENT RELOCATION TO ANNEX
<br />
<br />Project No. 21-1011 November 2024 092423-20
<br />
<br />a. Surface plane tolerance not to exceed 1/4 inch in 10 feet (6 mm in 3.0 m).
<br />b. Remove form ties, trim projecting concrete and fill honeycombs or other
<br />surface defects with appropriate patch or levelling material.
<br />c. Concrete: Provide for removal of form oil, curing compounds, efflorescence,
<br />coatings, salts, or other surface contamination, laitance or other surface
<br />conditions that could interfere with adhesion. Provide an absorbent surface,
<br />slightly scarified or with surface roughness, or both as specified.
<br />d. Concrete Masonry: Provide open texture concrete masonry units with flush
<br />joints, free of efflorescence, coatings, salts, or other surface contamination,
<br />weak surfaces or other surface conditions that could interfere with adhesion as
<br />specified.
<br />e. Do not install air barrier, stucco, primers or finishes over efflorescence, laitance
<br />or weak surface conditions, painted, coated, salt-contaminated, non-absorbent,
<br />smooth, or any concrete or CMU substrate where adhesion is in question, or
<br />when total stucco thickness (including finish coat) will exceed 5/8 inch (16
<br />mm). Use appropriate metal plaster base in these cases.
<br />5. Mechanical Ventilation: Maintain pressurization and indoor humidity levels in
<br />accordance with recommendations of ASHRAE. See 2013 ASHRAE Handbook -
<br />Fundamentals.
<br />D. Accessory Materials:
<br />1. Rough Opening Protection:
<br />a. Sto RapidGuard: One component STPE rapid drying gun-applied treatment for
<br />sheathing joints, rough openings, seams, cracks, penetrations and other static
<br />transitions in above grade wall construction such as: shingle laps over flashing,
<br />wall to balcony floor slab or ceiling, and through wall penetrations; pipes,
<br />electrical boxes, and scupper penetrations.
<br />2. Transition Detail Component
<br />a. StoGuard Transition Membrane: Flexible air barrier membrane for continuity at
<br />transitions; sheathing to foundation, dissimilar materials (CMU to frame wall),
<br />wall to balcony floor slab or ceiling, shingle lap transitions to flashing, floor line
<br />deflection joints, masonry control joints, and through wall joints in masonry or
<br />frame construction.
<br />b. Sto RapidGuard: One component STPE rapid drying gun-applied treatment for
<br />sheathing joints, rough openings, seams, cracks, penetrations and other static
<br />transitions in above grade wall construction such as: shingle laps over flashing,
<br />wall to balcony floor slab or ceiling, and through wall penetrations; pipes,
<br />electrical boxes, and scupper penetrations.
<br />E. Auxiliary Materials
<br />1. Wet sealant: Dow Corning 790, 791, and 795 sealants.
<br />2. Pre-cured sealant tape: Dow 123.
<br />3. Spray Foam:
<br />a. Sto TurboStick or TurboStick Mini Adhesive.
<br />b. Dow Great Stuff for Gaps and Cracks.
<br />F. Patching and Leveling Material for Prepared Concrete and Masonry: Sto ExtraSeal: polymer
<br />modified cement-based patch and leveling material for applications up to 3/8 inch in (10
<br />mm) in depth.
<br />G. Stucco Brown Coat:
<br />1. StoPowerwall Stucco Pre-Blended No. 102: Fiber reinforced one coat Portland cement
<br />stucco pre-blended with graded sand, and in compliance with ICC AC 11. See ICC ESR
