Step 3: Now, using your acoustical caulk and sheets of drywall it’s time to cover the Wall Blokker Pro with the drywall. Step 2: After you’ve covered the wall(s) with Wall Blokker Pro, seal up the seams between pieces with MLV seam tape. ![]() Have a friend hold the sheet up on the wall while you use a nail or staple gun to secure the Wall Blokker Pro to the wall. Cut the roll up into sheets that are the height of your wall so you aren’t trying to lug around a very heavy roll while hanging it up. Step 1: Wall Blokker Pro will come in a 4′ wide by 25′ long roll and it will weigh 100 pounds. If none of the above suggestions worked for you then it’s officially time to get started on soundproofing your existing wall(s). They’re very easy to get used to and help to cover/mask any disturbing noises you hear throughout the day. One last method to try before starting this project is getting a white noise machine. We always suggest doing this first because a 1% gap in a wall can let in 50% of noise, because sound is going to take the path of least resistance. If you see any, seal them up with acoustical caulk and, if you’re experiencing less noise this may be all you need to do. So if you share a wall with someone who watches TV too loud, treat your own side of the wall with soundproofing materials.Īdditionally, check the affected wall for any gaps or cracks. However, if you’re experiencing noise transfer between adjacent rooms soundproof the receiving side of the wall. Finding Sound Leaks in Wallsīefore starting a project like this, do you know where the sound is coming from? If it’s a street facing wall with a window, you can actually start with just soundproofing the window and if that doesn’t work you should work on the wall. If that’s not an option, consider the following steps to soundproof your existing wall by adding layers of mass loaded vinyl and finish sheetrock. If you have an existing wall in your space allowing excess noise transfer, consider tearing out one side to add an air gap. Seal the seams between each sheet of Wall Blokker Pro.Simply use this to attach the material to the existing wall.Wall Blokker Pro can be easily cut using a box cutter.You’ll use this to seal up the new drywall to ensure there aren’t any gaps that could cause sound flanking.Sound actually moves faster through solid materials, so if sound can’t even move from the first layer of drywall to the next, you’ll have a pretty soundproof wall. It’s the best option for layering over existing drywall, because it decouples the two rigid layers from each other. This is our EVA-based 1lb/sf mass loaded vinyl with a cotton scrim layer.Products and Tools You’ll Need to Soundproof Your Existing Wall NOTE: While adding layers may achieve an STC increase of 7-10 points, tearing a layer of drywall off, then adding a 2″ air gap and a new stud & drywall assembly may increase the STC by 15-20 points, or more! Consider the cost and benefit of each approach when budgeting your wall soundproofing project. Since, much of the time, demoing the existing wall is not an option, we’ll detail below how to add soundproofing layers to your wall without demolition. You have two primary options: tear the existing wall down (at least one sheet of drywall on one side), or add to the existing wall assembly. The short answer is yes, you can soundproof existing walls, but it’s going to take a lot of work and won’t be as effective as soundproofing the wall during construction. Our guide below will outline best approaches to soundproofing existing walls, whether demolition is an option or not. Existing walls are tough to soundproof, since they’re already closed up with drywall on each side, and the most effective way to greatly increase their soundproofing level is to take down a layer of drywall and add air gaps. This is essentially the number of decibels, or dBA, that the wall is blocking. Keep in mind that soundproofing walls are measured in what’s known as STC, or Sound Transmission Class. It’s going to be a pretty involved process no matter what, but we’ll provide you with the least complicated steps to soundproof existing walls. Soundproofing a wall in your home after construction is already complete can be a pain. ![]()
