GREENchoice Titebond Acoustical Sound Sealant is a non-flammable, latex-based acoustic sealant product designed specifically for the reduction of noise transmission in wall partition systems. The primary function of acoustic sealants are to achieve and maintain the specific STC (Sound Transmission Class) value of the system designed. GREENchoice Titebond Acoustical Sound Sealant remains permanently flexible and adheres firmly to wood or metal studs, concrete, gypsum board, and most other types of building substrates. The unique formulation of this acoustical sealant is non-drying, non-hardening, non-staining and non-migrating. The GREENchoice Titebond Acoustical Sound Sealant is used for preventing noise transmission in unexposed applications at perimeter joints, floor and ceiling runners (either wood or metal runners), cutouts in gypsum board, veneer plaster systems, and other areas where a sound rated assembly is required.

Acoustical Performance – STC Rating
Edge Detail STC Value Comment
Uncaulked 29 This open-edge track gave the STC value of 29 through direct leakage.
Single bead at the perimeter of one base layer 49 The bead closed void but did not seal leakage around the joint between wallboard and track.
Two beads, one under each base layer of gypsum board 53 The beads closed void and sealed leakage around track.

Note: Taken from ASTM C919. The test partitions of metal studs 610 mm (24 in.) on center, with double layers of 13 mm (0.5 in.) wallboard screw-attached to each side. Sound attenuation blanket, 38 mm (1.5 in.), was placed in the void. The partition panels were erected, shimmed out 3 mm (0.125 in.) at the periphery: top, bottom, and edges.

GREENchoice™ Application Guidelines

Application Temperature

Above 40°F (4°C)

Service Temperature Range

-20°F to 150°F (-29°C to 66°C)

Method of Application

Cartridge/caulking gun

Working Time

Approximately 20 minutes for a 1/4″ bead

Working Surfaces

Surfaces to be sealed should be clean, dry and free from oil, grease and any other material that may deter adhesion.

Cleanup

Clean with water while caulk is wet. Scrape off dried excess caulk with a putty knife.

Limitations

If using wall soundproofing outside, do not apply if rain is expected within 12 hours. Not recommended for continuous submersion or use below the waterline. For best results, store above 40°F. This product is freeze/thaw stable.

Tack-free Time

30-60 minutes.

Full Cure

3-7 days. Cure will be affected by joint size, configuration, and environmental conditions.
