Supress® Soundproofing Adhesive for Drywall (AS387) and Wood Structures (AS487)
Supress Soundproofing Adhesive is an easy, low-cost upgrade for existing structures, providing the highest STC and IIC performance available in standard assemblies.
Supress Soundproofing Adhesive for Wood (AS487) dramatically reduces impact noise, including footfall/walking on hard surfaces-making the product ideal for floors and connected shear wall assemblies.
Supress Soundproofing Adhesive for Wood (AS487) is a high-performance, professional grade, water-based damping compound specifically designed for laminating wood panels such as Plywood, Oriented Strand Board (OSB), Particle Board and Medium-Density Fiberboard (MDF) used in floors, walls and ceiling assemblies.
Each standard size tube fits existing equipment on the job site, and covers an average of 15-25 square feet with no hazardous chemicals of solvents--making it extremely environmentally friendly.

Planning/Design for Your Project
For the best results in your project, please consider the following:
Air and structure-borne sound are very aggressive in nature and tend to spread out through a building's structure. Open attic areas and plenums above acoustical ceilings allow sound to travel through "flanking" the walls below. For example, to suppress the unwanted sound you perceive as coming through a common wall, you may need to extend your coverage to the adjacent hard flooring surfaces, walls, and ceilings including soffits or other architectural elements.
Wall, floor and ceiling penetrations create paths for sound. Make sure that any openings for recessed lighting, audio speakers, electrical outlets, fire sprinklers, etc. are fully sealed, otherwise sound energy may pass through these areas, reducing overall acoustic performance. Doors and windows also create paths for unwanted sound. Remediate or specify the appropriate assembly for the performance desired.
Suppressing sound or noise traveling through walls made of concrete, concrete block, brick or similar materials may require a narrow stand-off such as furring strips or lightweight metal studs in the assembly for maximum acoustic performance. Please discuss the details of your specific application with a Supress representative.
How to Order Supress Soundproofing Adhesive
Supress Soundproofing Adhesive is available in 29 ounce tubes which fit standard quart-size caulking guns.
How to Use Supress Soundproofing Adhesive
Surface Preparation: Surfaces must be thoroughly clean and free from saw dust, dirt, grease, oils, wood chips, release agents, coatings and any other contaminants that may affect adhesion.
Application: Read installation instructions before use. Apply at between 50-100 degrees for best results. Cut tip and puncture cartridge inner seal using circular motion to enlarge opening in seal completely. Apply with conventional caulking gun and spread evenly over first panel surface. Place second panel over coated area within 15 minutes and press together evenly to insure complete and consistent adhesion. Allow assembly to cure for 24 hours, longer if temperature is less than 70 degrees F. Use nails, screws or other mechanical fasteners at 8" intervals on edges and at 12" intervals in center to install laminated panel into floor, wall, or ceiling assembly.
Cleanup: Immediately remove all excess sealant or smears as work progresses with soap and water.
Precautions: For all Supress products, and for other products used in conjunction with Supress products, users must follow individual product labels and Material Safety Data Sheet (MSDS) for warnings and precautions prior to opening containers and during use and storage.
