GREENchoice Titebond Acoustical Sound Sealant is a non-flammable, latex-based product designed specifically for the reduction of sound transmission in wall partition systems. Its primary function is 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. Its unique formulation is non-drying, non-hardening, non-staining and non-migrating. The GREENchoice Titebond Acoustical Sound Sealant is used for unexposed applications at perimeter joints, floor and ceiling runners (either wood or metal), 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.
Above 40°F (4°C)
Service Temperature Range
-20°F to 150°F (-29°C to 66°C)
Method of Application
Approximately 20 minutes for a 1/4″ bead
Surfaces to be sealed should be clean, dry and free from oil, grease and any other material that may deter adhesion.
Clean with water while caulk is wet. Scrape off dried excess caulk with a putty knife.
If using 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.
3-7 days. Cure will be affected by joint size, configuration, and environmental conditions.
