PART 2 - PRODUCTS


A. Provide acoustical joint-sealant products that effectively reduce airborne sound transmission through perimeter joints and openings in building construction, as demonstrated by testing representative assemblies according to ASTM E 90. Acoustical Sealant shall maintain required or indicated STC ratings at sound rated partitions.

2.2 ACOUSTICAL JOINT SEALANTS

A. Acoustical Sealant for Exposed and Concealed Joints: Manufacturer's standard nonsag, paintable, nonstaining latex acoustical sealant complying with ASTM C834 and C919. 1. Manufacturers: Subject to compliance with requirements, provide products by one of the following:

a. GE Construction Sealants; Momentive Performance Materials Inc. b. Hilti, Inc. c. Pecora Corporation. d. Tremco Incorporated. e. United States Gypsum Company.

2. Colors of Exposed Acoustical Joint Sealants: As selected by Architect from manufacturer's full range of colors.

3. Acoustical sealants in fire rated or smoke rated assemblies: a. Manufacturers: Any of above meeting criteria below. b. Flame-spread and smoke-developed ratings: Less than 25 per ASTM E84. c. Available product: Hilti CP 502.


A. Primer: Material recommended by acoustical-joint-sealant manufacturer where required for adhesion of sealant to joint substrates.


ACOUSTICAL JOINT SEALANTS 07 92 19 - 2 OF 2

B. Cleaners for Nonporous Surfaces: Chemical cleaners acceptable to manufacturers of sealants and sealant backing materials, free of oily residues or other substances capable of staining or harming joint substrates and adjacent nonporous surfaces in any way, and formulated to promote optimum adhesion of sealants to joint substrates.

C. Masking Tape: Nonstaining, nonabsorbent material compatible with joint sealants and surfaces adjacent to joints.

PART 3 - EXECUTION

3.1 EXAMINATION / PREPARATION / GENERAL

A. Comply with the following: 1. Joint-sealant manufacturer's written instructions, recommendations, restrictions and limitations, unless more

stringent requirements apply. 2. Examine joints indicated for compliance with requirements for configuration, tolerances, and conditions

affecting performance. 3. Proceed with installation only after unsatisfactory conditions have been corrected. 4. Surface Cleaning: Clean out joints immediately before installation. Make surfaces dust free. 5. Joint Priming: Prime joint substrates where recommended.. Apply primer properly, and Confine to areas of

joint-sealant bond; do not allow spillage or migration onto adjoining surfaces. 6. Masking Tape:

a. Use where required to prevent contact of sealant or primer with adjoining surfaces or permanent staining or damage, or by clean as required to remove sealant smears.

b. Remove tape immediately after tooling without disturbing joint seal.

3.2 INSTALLATION OF ACOUSTICAL JOINT SEALANTS

A. STC-Rated Assemblies: Seal construction at perimeters, behind control joints, and at openings and penetrations with a continuous bead of acoustical joint sealant. Install acoustical joint sealants at both faces of partitions, at perimeters, and through penetrations. Comply with ASTM C 919, ASTM C 1193, and manufacturer's written recommendations for closing off sound-flanking paths around or through assemblies, including sealing partitions to underside of floor slabs above acoustical ceilings.

B. Acoustical sealants at penetration in fire rated assemblies: Seal openings and penetrations under provisions of 07 84 00 Fire / Smoke Stopping. Do not use acoustical sealants of this section.

3.3 CLEANING

A. Clean off excess sealant or sealant smears adjacent to joints as the Work progresses by methods and with cleaning materials approved in writing by manufacturers of acoustical joint sealants and of products in which joints occur.

3.4 PROTECTION

A. Comply with Division 01.

B. repair damaged or deteriorated acoustical joint sealants immediately so installations with repaired areas are indistinguishable from original work.
