Steps on How to Hang Acoustic Foam without Damaging Walls
Below is a step by step guide on how to hang acoustic foam without damaging walls.
If you live in a rented unit and would like soundproofing methods that don’t interfere with the structural integrity of the building, try these hacks.
1. Installing the Foam with Adhesive Squares
You can install acoustic foam without damaging the walls or making a mess through adhesive sprays.
Adhesive squares are easier to use, and it does not take much time to dry out.
Also, the adhesive squares create a strong bond between the foams and the wall.
Follow these steps to install the foam:
- Locate the source of the noise on the wall, then mark it using a pencil or a marker pen.
- Then clean the area thoroughly using a clean piece of cloth and the right solvent such as isopropyl alcohol.
- Once the area has dried, peel the liners from the adhesive squares.
- Apply the liner you have peeled on the side of the foam and ensure you apply enough pressure for a few seconds.
- Apply several of them on the foam until you are sure it’s enough.
- Peel the adhesive liner you have attached on the wall from the other side, then attach the foam to the area you had marked on the wall.
- Hold it in place for a few seconds to ensure it sticks.
- Repeat the process with the other foam on the other part of the wall.
Remember, you should press firmly on the applied surface when applying the foam to ensure it sticks properly.
2. Use Spray Adhesive
Another product you can use is spray adhesive.
The spray comes in aerosol cans, which makes it easy for your work.
A good example of the spray adhesive is 3M General Purpose 45 Spray Adhesive because it is not messy, and it easily bonds well with materials.
Besides, it is economical, and it does not drip when sprayed on surfaces.
If you want to install the foam using spray adhesive, follow these steps:
- Mark the area on the wall where you intend to install the foams using a pencil or a marker.
- Clean the area effectively and ensure it has dry before you attach the foams.
- If you used a solvent to clean the area, ensure you dry it with a clean piece of cloth such as a towel.
- Cover the surrounding wall and the floor with old newspapers of clothes that you no longer use to avoid damaging the paint areas.
- Keep in mind that when using the spray adhesive, your room should be at least 70 degrees Fahrenheit (21° C)
- Spray the adhesive on the wall where you intend to mount the foam and also on the back of the foam.
- Then gently attach the foam to the wall where you have sprayed the adhesive.
- Before attaching the foam, ensure you give the adhesive a few seconds before attaching the foam.
- Once you have attached the foam, press it gently against the wall for a few seconds to ensure it sticks properly.
3. Use Push Pins
Pushpins are also good at installing acoustic foams without damaging the walls.
Pushpins are small pins that are usually inserted by hand, unlike nails.
You need to attach the pins on the foam then mount it on the wall, which is the biggest entry for noise.
When purchasing the pins, go for the ones that are 1.5 inches long as they are much effective at attaching to the foam and the wall.
The great thing about push pins is that you don’t need too many of them; two or three are enough for the job.
However, hard wall surfaces can make it hard for the pins to attach.
In this case consider other means of attaching them.
A good way to try is using cardboard.
Follow these steps if you want to attach the foams on cardboard using push pins:
- Look for a cardboard that is similar in size to the foams you intend to use.
- Ensure the cardboard is clean before; if not, clean it by removing dust and dirt to make it easier for the pins to stick.
- Attach the foams by pressing them gently on the cardboard.
- Use double adhesive tape to cardboard, then stick it to the wall.
4. Use a Double-sided Velcro/tape.
You can use a double-sided Velcro or tape as a way to attach the foam without damaging the wall.
The tapes are easier to use and install without special skills, particularly if you live in a rented space.
When using this method, ensure the surface, you intend to attach the foam, and the tape is clean and free of moisture.
One advantage of the tape is that it can easily be removed when you want to move out or remove the foam completely.
Also, ensure you clean the area well and dry it properly because the tape won’t stick if there is dirt or debris.
5. Use Command Strips
Command strips are also good at hanging acoustic foams without damaging the walls.
The strips do not leave residue on the wall like other types of adhesive.
When purchasing the command strips, ensure you purchase enough for the foams.
Ensure you have at least command strips for each square foam.
Some companies provide information on how to attach the command strips; if yours did not have the information, follow these steps:
- Start by measuring the area on the wall, then mark it using a pencil or marker pen.
- Clean the surface using the right solvent such as isopropyl alcohol.
- Allow the area to dry or you can use a clean piece of cloth or towel to dry it.
- Remove the liners on the command strips, attach it to foam, and attach it to the well.
- Ensure you press it firmly for a few seconds to let it attach to the wall.
- Repeat the process for the other foams until the whole wall is covered with the foams.
- Also, ensure the tiles have aligned with each other.
You can also use a stapler to install the acoustic foam as long as you don’t mind a patchable hole on the walls.
All you need to do is glue cardboard to the foam’s back, then staple it on the wall.
This method is cheap and requires minimal effort.
