LIQUID NAILS® Construction Adhesives: Tips & Tricks

Maximize Sound Deadening with Acoustical Sealant

The perceived quality of a wall is determined partly by its sound deadening abilities. Luckily, there is an easy and low-cost solution.

Have a Question?

LIQUID NAILS^® Brand Acoustical Sound Sealant (AS-825) is specially formulated to seal off the tiny gaps and crevices that let airborne noise pass through.

Proper use of acoustical sealant has proven to drastically improve sound deadening. For example, simply placing a bead of sealant on each side of the wall assembly where the wallboard meets the ceiling member can improve the Sound Transmission Class (STC) rating from 29 to 53, as demonstrated by the ASTM C919 Standard Practice for Use of Sealants in Acoustical Applications.

For optimal sound deadening results, follow the steps explained below.

For New Construction:

Before installing drywall, add a 1/4" (6mm) bead of LIQUID NAILS Brand Acoustical Sound Sealant (AS-825) along both the sill plate and the top plate.
Install the drywall, supplementing screws with LIQUID NAILS Brand Drywall Adhesive. (This specialized wall adhesive helps prevent screw pops and provide additional sound deadening.)
Use LIQUID NAILS Brand Acoustical Sound Sealant to seal around all seams and openings, including cutouts, electrical boxes, perimeter joints, windows and any other areas where air (and therefore sound) may pass through.
Apply a second 1/4" (6mm) bead of LIQUID NAILS Brand Acoustical Sound Sealant (AS-825) where the drywall meets the floor and ceiling.

For Retrofitting:

Apply a 1/4" (6mm) bead of LIQUID NAILS Brand Acoustical Sound Sealant (AS-825) where the existing drywall meets both the floor and the ceiling.
Seal around all seams and openings, including electrical outlets, perimeter joints, windows and any other areas where air (and therefore sound) may pass through.
Install a second layer of 1/4" drywall, supplementing screws with LIQUID NAILS Brand Drywall Adhesive. (This specialized wall adhesive helps prevent screw pops and provide additional sound deadening.)
Apply a second 1/4" (6mm) bead of LIQUID NAILS Brand Acoustical Sound Sealant (AS-825) where the top layer of drywall meets the floor and ceiling.
