SCORE AND SNAP:

• QuietRock 510 may be scored with any utility blade. We have found that the best blade is the Irwin Blue Blade (available at most building supply dealers).
• Score QuietRock 510 deeply (2 times to a depth of 1/4″) on one side, making sure to cut the paper in the center of the board, and snap against a straight edge.

HANG AS USUAL:

• Secure QuietRock to the studs using appropriate #6 or #7 Bugle Head 1 5/8” to 2” drywall screws (every 12” to 16” or as required by code). Use coarse thread for wood studs and fine thread for metal studs. Nails may also be used. You may also place QuietRock 510 over existing drywall in retrofit applications, except on ceilings. Be sure to use screws or nails, and not glue, in hanging QuietRock.*
• Finish securing the QuietRock panel to the studs with drywall screws. The screw head should go just below the surface of the paper. Be careful to drive the screws only enough to dimple the surface it’s easy to over tighten and cause the screw head to go all the way through the paper surface. If you accidentally break through the surface, drive another screw nearby.
• Apply 1/8” – 3/8” bead of sealant, such as QuietSeal, around the entire perimeter of the wall [or ceiling for the ceiling instructions] and filled in between any seam that is not backed by a stud or joist. For further noise protection, before putting up each sheet, apply 1/8” – 3/8” bead of sealant, such as QuietSeal, around the panel perimeter (on the edges of the panel) and then install the adjacent sheet of QuietRock, “squeezing” QuietSeal between them. Be sure to remove excess sealant with a rag (any paint thinner easily removes the sealant) or putty knife as needed. DO NOT LEAVE ON THE SURFACE, AS IT CAN INTERFERE WITH TAPE AND MUD. QuietSeal will remain viscoelastic, i.e. not dry, so it is necessary to tape and texture over the joints. Always use QuietSeal, or similar, around electrical boxes and at the wall perimeter to seal all air gaps completely. See QuietSeal instructions for more detailed information and apply QuietSeal in accordance with applicable requirements of ASTM C919.
• Use QuietPutty®, or similar, behind outlet or other boxes. Wrap the putty completely around the back side of the box.

FINISH AS USUAL:

• After the QuietRock is in place, apply drywall tape along the joints between the two pieces of drywall. The tape helps hold drywall compound in the gap.
• Use a wide drywall knife to spread joint compound over the tape. Don’t try to fill the entire gap all at once; apply a little at a time, and allow it to dry before applying a second coat.
• Cover the screw heads with drywall compound.
• Allow the joint compound to dry then sand it smooth. Wear breathing protection during this step because the process generates a lot of dust.
• Apply a second coat of drywall compound, allow it to dry, and sand it smooth. Repeat the process as necessary until the wall is perfectly smooth then finish the wall as desired. BE SURE TO FOLLOW THE COMPOUND MANUFACTURERS INSTRUCTIONS.
