How to Hang Acoustic Foam with Minimal Damage

If you’re renting an apartment and don’t want to leave walls with holes from push pins or residue from adhesive, you’d better stick with 3M command strips popularly used for hanging pictures.

They don’t leave residue on the wall.

Alternatively, you can mount the foam on a piece of coroplast, plywood, or thick cardboard with an adhesive.

Then hang the assembled panel on your wall. This technique not only prevents the walls from damage but also allows you to freely move the panel around or take them with you when moving out.

Hanging Acoustic Foam with Adhesive Squares

Use a pencil or masking tape and mark the position of foam panel on your wall

Thoroughly clean the wall surface using denatured alcohol or isopropyl. Then wipe the area clean with a paper towel or rag and let dry. Avoid common cleaners because their ingredients can interfere with the strength of the bond.

Remove one paper liner from the adhesive square and apply the square on the backside of the panel near the edges.

Apply some pressure for 30 seconds to make sure the adhesive squares form a strong board with the foam.

Remove the second paper liner and mount the panel in the desired location and apply pressure for about 30 seconds.

Number of adhesive squares needed per panel

  • 1 inch = 2 adhesive squares
  • 2 inch = 3 adhesive squares
  • 3 inch = 4 adhesive squares
  • 4 inch = 4 adhesive squares

Cover the areas you won’t be spraying with newspaper, cloths or painter’s plastic to protect your room

When installing make sure the room temperature stays at around (21° C) 70° F for best performance

Apply enough adhesive to the rear side of the acoustic foam. You can apply some on the mounting area as well.

Allow for 10-15 seconds for the adhesive to become sticky

Gently place the foam against the adhesive coated mounting and apply pressure for about 30 seconds

Where to Place Acoustic Foam

Ensure that you treat the reflection spots on the horizontal axis.

Here’s how to do it, simply sit in your listening position and imagine where sound coming from the speakers hit the side walls and reflects back to you.

It’s important to hang acoustic foam treatment here to help improve your stereo width and make the audio quality much better.

Beware of Weak Areas

Consider hanging some acoustic foam panels between your front wall and the speakers. Doing so helps significantly reduce reflections coming from the back of your speakers.

However, it’s tricky doing so as the boundary interactions in this case can cause a major dip in the low-mid frequencies. But for most home studios, it’s the best place to place the speakers close to the walls as advised by the manufacturer.

But if there’s any space left between the speakers and the wall, place acoustic foam panel there.

Never forget the corners

Mount some of the acoustic foam on the corners of your room or even where the ceiling meets the sidewall.

As your studio grows over time, you will need to add bigger and thicker foam in your corners to help reduce resonance.

Create Acoustic Cloud

You can hang acoustic foam a few inches from your ceiling and directly above your listening position and your musical instruments. This will help prevent reflections above you.
