Method B: Attaching the Quiet Barrier® HD to the Back of the Gypsum Board.

1. Install the Quiet Batt® between the studs.

2. Lay the 5/8 inch drywall face down on to a clean dry surface. Apply a ¼ inch bead PL Construction adhesive around the perimeter of the backside of the drywall. Apply the adhesive approximately 2 inches from the edge of the drywall. Create an X pattern corner to corner and place a few 1 inch “globs” of glue with the field.

3. Place the Quiet Barrier® material onto the back side of the drywall. To ensure good contact with the adhesive, use a hand roller to apply pressure. Let the adhesive cure for 24 hours before installation.

4. Place the first sheet of drywall / Quiet Barrier® composite vertically on the studs. Leave a ¼ inch gap between the new layer of gypsum board and all adjoining wall, ceiling and floor surfaces.

5. Attach the drywall with 1 5/8 inch coarse thread drywall screws. Screws should be placed 8 to 12 inches apart.
