It should never be sandwiched between layers of drywall unless you can provide a dead air space where in the MLV can resonate or move with the sound waves. The MLV works well when placed on a wall or ceiling in a membrane fashion. This method is known as the membrane or septum method. The standard of the industry is to install the MLV directly to the stud or joist framing using an industrial stapler or heavy-duty roofing nails that have the large plastic heads. Also be sure to use STC rated putty pads on the back of your outlet boxes, as sound can flank through these as well.There is more than one method for installing mass loaded vinyl to obtain maximum effect. In the event that you have more than ¼” between the penetration and the MLV, this gap should be filled with acoustical caulk to avoid any sound flanking once the wall is finished. This should give you a good guide for the cutout. A good method here to avoid cutting too far from the penetration is to press down around the penetration, and an indent should show slightly in the vinyl barrier. It can be hard to tell where you’re cutting around a penetration such as an outlet or light switch, because the mass loaded vinyl will be covering the object you need to cut around.

The best thing you can do is leave the screw in place and tape over it with Seam Seal tape. If in the event that you miss with the screw and hit the cavity rather than the stud, be sure not to remove the screw. It can be hard to tell where exactly the stud is when using the nail gun to attach the MLV.
Luckily there are a few very affordable materials that can be used to fix these errors, and those are acoustical caulk and seam seal tape. These are all very easy mistakes to make, mainly because MLV is so easily cut using a razor blade, so it’s not unreasonable to cut a bit more than intended.
