Sound Damp
Drywall Damping Compound
Sound Damp can save valuable installation time with its more efficient application method. Damping compounds are traditionally applied with caulking guns. Sound Damp replaces tubes and caulking guns with an inexpensive and disposable low-nap roller. Sound Damp is applied continuously across the entire back of the drywall sheet, reducing application time and eliminating the guesswork of proper consistency.

Installation Guidelines
-
- Notes
- Store between 40-120˚F (5-49˚C)
- Apply at room temperature
- Approximately (11) 4'x8' sheet coverage per 5 gallon bucket
- Preparation
-
- 1. Clean all surfaces free of dust & debris. Surface must be smooth and free of obstructions, such as nails, excess joint compound, etc.
- 2. Install first layer of wall/ceiling/floor sheathing or gypsum board per material manufacturer’s installation instructions.
- 3. Use acoustic sealant around all cut-outs.
- 4. Prepare second layer of material for any cut-outs and clean back surface of dust & debris.
- 5. Stagger all sheathing or gypsum board seams.
-
- Sound Damp2
-
- 1. Apply Sound Damp2 over back of second layer with bucket trowel or putty knife. Evenly distribute approximately 55-60 oz. per 32 square foot of wall/ceiling/floor area.
- 2. Using a short nap paint roller cover, roll to a thin continuous layer.
- 3. Fasten Sound Damp2 treated layer of sheathing or gypsum board (per manufacturer’s instructions) over first layer area within 10 minutes of application, sandwiching Sound Damp2 between the layers.
- 4. Apply acoustic sealant around wall and/or ceiling perimeter and penetrations.
- 5. Clean up with warm water

FAQ
-
“Can I add Sound Damp2 on the outside of the wall to make it quieter?”
No, Sound Damp2 is designed to be used between two or more layers of gypsum board, OSB, or plywood.
-
“Sound Damp2 froze solid on the jobsite, is it ruined?”
No, simply allow for complete thawing and then apply at room temperature.
-
“What kind of surface prep is needed to apply Sound Damp2?”
If applying to basic, untreated building materials such as gypsum board, OSB, or plywood, no primer or paint is necessary. Reference the installation guidelines for more details.
-
“Can I use Sound Damp2 on exterior or outdoor wall applications?”
Sound Damp2 can be installed between layers of building materials. However, acoustical performance will decrease as temperature lowers beyond indoor room environments.

- 5 gallon pail covers 370 sq/ft (11 - 4' x 8' sheets)
- No special guns or applicators required
- Mildew and water resistant
A secondary benefit of damped drywall, when used in critical listening spaces, is reduced room reverberation times and improved low frequency absorption. The room simply sounds better, more articulate. This room acoustics improvement is often desirable in music performance, recording, and home theater spaces.
