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
