Steps to Soundproof a Wall

1. Measure the height of the wall. Roll out the 2lb MLV so the length of the material matches the wall's height. Cut the mass loaded vinyl using a sharp utility knife and a T-square to ensure you make a straight cut. You can also cut the MLV with a good pair of upholstery scissors. Just be careful you don't make crooked cuts!
2. Fasten the MLV to the wall using staples, screws or nails. Start attaching the MLV at the top of the wall, and work your way across ensuring the MLV stays straight. Be sure to add enough fasteners to support the 2lb MLV weight before allowing the MLV to hang. 
3. The preferred installation method is to install MLV to a wall that has insulation and framing, but no drywall yet. There are a variety of installation methods that will improve performance, such as sound isolation clips or a double wall, but if you are not an experienced installer, we recommend to just focus on the basics, and ensure you have a sturdy install that is airtight and gapless.
4. If the wall already has drywall, we recommend removing the existing drywall. If you choose to install MLV on top of drywall, it must be attached to the studs or joists. Drywall will not support the weight of MLV.
5. After you've finished attaching the MLV to the studs and the bottom of the wall, repeat the steps you just did for your second cut off the MLV roll. Do not cover any wall outlets or light switches. Leave them exposed.
6. As you work your way across the wall, keep the ends of the MLV directly next to each other. (AIRTIGHT!) If the MLV edges connect on a stud, use acoustic caulk to seal the gap. If the MLV edges connect over an air gap, use foil tape to seal the edges.
7. After you've finished getting the MLV up on the wall, use your acoustic sealant caulk to seal ALL of the edges, both between the sheets of MLV and between the MLV and the wood studs. THIS IS A KEY STEP TO ENSURE YOUR BARRIER IS AIRTIGHT. If you have not hung drywall, now's the time to begin installing 5/8" drywall on top of the MLV.
