Sand glossy paint to improve adhesion
Acoustic foam can be mounted on walls using a variety of methods, such as double-sided adhesive tape, spray adhesives, glue, thumbtacks, and pins. However, it is unclear whether 3mm tape can effectively hold acoustic foam on glossy paint.
To improve the adhesion of paint on glossy surfaces, it is recommended to sand the surface lightly before painting. This helps to create a better bond between the paint and the surface, ensuring that the paint adheres properly and lasts longer. Here are some steps to follow when sanding glossy paint to improve adhesion:
First, ensure that the glossy surface is clean and free of any dirt, dust, grease, or grime that may interfere with the adhesion of the paint. Use a mixture of warm water and a mild detergent, applied with a sponge or cloth, for general cleaning. If there are stubborn stains, such as mould or mildew, use specialised mould removers. Once the surface is clean, allow it to dry completely before proceeding to sanding.
When sanding, use medium-grit sandpaper to lightly scuff the surface. This will help remove any existing sealant or oil-based paints, creating a better bond for the new paint layers. Sanding the surface will also help to remove any glossy finishes from previous paint applications, ensuring that the new paint adheres properly.
It is important to note that not all surfaces require sanding. For most drywall interior painting projects, multiple coats of quality paint may be sufficient to cover the area without the need for sanding. However, if using cheaper paints that are more prone to leaving brush marks or peeling over time, it is advisable to lightly sand the surface with fine-grit sandpaper.
Additionally, if you are painting over gloss paint, you may consider using a super grip primer before applying the new paint. This can save you time and effort by avoiding the need for extensive sanding, especially on intricate surfaces. However, if the surface is subjected to more wear and tear, such as skirting boards or door frames, it is recommended to sand the surface before painting to ensure better adhesion.

Use a hybrid adhesive sealant
When mounting acoustic foam panels, hybrid adhesive sealants are a smart option for those seeking a permanent solution. Hybrid adhesive sealants are applied using a manual silicone gun, and they offer strong adhesion that withstands temperature changes, moisture, and vibrations.
For those in Europe, Den Braven's Hybrifix 125 is a recommended hybrid adhesive sealant for mounting acoustic foam panels. A 290ml cartridge can mount approximately 40 panels (50 x 50cm) and costs around €5.
Before applying a hybrid adhesive sealant, it is important to properly prepare the mounting area. This includes cleaning the walls with isopropyl alcohol to remove dust, oils, or debris. If dealing with shiny paints and finishes, lightly sanding the surface can improve adhesion.
Additionally, ensure that the acoustic foam panels and the mounting surface are prepared according to the adhesive's instructions. This includes following the recommended spread rate and application method. Once the adhesive is applied to both the panels and the mounting surface, carefully press the panels into place, applying even pressure to promote full contact bonding.
While hybrid adhesive sealants offer strong adhesion, they may not be suitable for those seeking a non-permanent solution. In such cases, other options like adhesive sprays or double-sided tape might be more appropriate.

Try double-sided tape with super glue
While installing acoustic foam, it is essential to ensure a secure and lasting hold to avoid any peeling or damage to the mounting surface. One effective method to achieve this is to use double-sided tape with super glue.
Double-sided tape is a popular choice for mounting acoustic foam panels. It offers convenience and ease of installation. The tape is designed to provide a strong and reliable hold, comparable to heavy-duty mounting tape. However, some users have reported that double-sided tape alone may not be sufficient for long-term adhesion, especially on certain types of walls.
To enhance the adhesive strength and ensure a more permanent solution, consider using super glue in conjunction with double-sided tape. By applying a small amount of super glue to the centre of the double-sided tape, you can create a stronger bond that can better withstand the weight of the acoustic foam. This combination allows the tape to hold the foam in place while the super glue sets, resulting in a more durable and secure installation.
It is important to test this method on a small area first to ensure that the super glue does not damage the foam. Additionally, make sure that the mounting surface is clean and non-textured for the best adhesion.
Some products on the market, such as the SoundAssured Acoustic Foam adhesive squares, offer a similar solution with pre-cut adhesive squares that provide a strong and reliable hold without the need for additional tools or messy glues. These adhesive squares are engineered with a durable gel adhesive and are designed specifically for mounting acoustic foam panels.
By combining double-sided tape with super glue or utilising specialised adhesive squares, you can achieve a secure and long-lasting installation of your acoustic foam panels, ensuring they remain firmly in place.

Opt for adhesive spray
If you're looking for an alternative to 3mm tape for mounting acoustic foam, adhesive spray is a great option. Adhesive sprays, such as Krylon EASY-TAK, 3M Scotch, Loctite, and Foamtak, are designed to attach acoustic foam to various surfaces, including drywall, wood, plastics, cardboard, and metals. They offer a strong and permanent bond, ensuring your acoustic foam stays securely in place.
When using an adhesive spray, it is important to follow the manufacturer's instructions for the best results. In general, you will need to apply the spray to both the installation surface and the acoustic foam itself. The Loctite spray adhesive, for example, requires you to hold the can vertically, position it 8 to 10 inches away from the surface, and keep it moving to create an even coat. It is also important to ensure that the surfaces are clean, dry, and free of foreign materials before applying the adhesive.
One advantage of using adhesive spray is its ease of use and convenience. Simply spray the adhesive on the desired surfaces, allow it to dry for a few minutes, and then firmly press the acoustic foam onto the installation surface. This method eliminates the need for cutting or measuring tape, and it does not require any tools or messy glues.
Additionally, adhesive sprays offer flexibility in terms of repositioning. While some sprays, like Loctite, are not suitable for repositioning, others like Krylon EASY-TAK are designed to be repositionable. This feature is especially useful if you need to make adjustments or relocate your acoustic foam panels without damaging the walls or the foam itself.
However, it is important to note that not all adhesive sprays are created equal. Some users have reported that certain sprays may not hold the foam securely, especially if the mounting surface has texture. It is always a good idea to test the adhesive on a small area first and follow the manufacturer's recommendations to ensure compatibility with your specific application.
