Q: I’d like to convert a spare bedroom into a music room. Do you have any advice on soundproofing an existing room?
A: To reduce airborne sound transmission, you can retrofit existing drywall walls with a combination of Acoustical Sound Sealant and an additional layer of ¼-in. drywall. To do so, the experts at Liquid Nails recommend first applying a 1/4-in. bead of Sound Sealant where the existing drywall meets both the floor and the ceiling. Next, seal around all seams, openings and outlets where air (and sound) may pass through. Install the second layer of ¼-in. drywall, supplementing screws with Liquid Nails Drywall Adhesive. (This specialized wall adhesive helps prevent screw pops and provides additional sound dampening.) Finish by applying a second ¼-in. bead of Sound Sealant where the top layer of drywall meets the floor and ceiling.
