I have had many of my soundproofing students ask me where to use acoustic caulk. This is one of those important but often glanced over parts of soundproofing. In this article I will teach you exactly where to use acoustic caulk for your soundproof studio.

1) Where The Walls Meet The Floor

Anywhere the drywall meets the floor you need to run a bead of acoustic caulk along that seem. You can also leave an 1/8" gap between the drywall layers and the floor and push in backer rod into the gap and then fill it with acoustic caulk. This will give you just a bit more isolation from the floor and the wall.

2) Where your walls meet in the corners of your room

Anywhere you have two layers of drywall meeting in a corner you need to place acoustic caulk along that seem. If you want a bit more isolation with your walls you can leave an 1/8" air gap between your first layer of drywall and put in backer rod and acoustic caulk. Then you can do the same thing with the second layer, adding backer rod and acoustic caulk. This will help isolate your walls from each other.

3) Where The Walls and Ceiling Meet

Anywhere your walls meet your ceiling you will need to place a bead of acoustic caulk along that seam. Again, to add isolation you can leave an 1/8" air gap and place some backer rod and acoustic caulk in between both layers of drywall.

4) Anywhere there are small holes or cracks

Construction is not perfect, but your room needs to be airtight. To accomplish this we need to use acoustic caulk around all electrical boxes for lights or light switches or plugs. Use acoustic caulk where the drywall and boxes meet. You can use it around small holes like we did when running an ethernet cable through the wall. Use your best common sense when it comes to sealing up any holes in your room.
