1. Use a stud finder to locate the joists within the ceiling. Mark the joists with a chalk line.

2. Lay the ½ 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. Attach the drywall / Quiet Barrier® composite with 2 inch coarse thread drywall screws. Be sure the screws penetrate the joists within the wall assembly. Screws should be placed 8 to 12 inches apart.

5. Leave a ¼ inch gap between the new layer of gypsum board and all adjoining wall, ceiling and floor surfaces.

6. Fill the ¼ inch gap with OSI® Pro-Series® SC-175™ Acoustical Sound Sealant.

7. Finish the gypsum board using common industry standards.
