How to Install Sound Deadening

How to install sound deadening?  Why do you need Deadener? Do you hear that? It’s your trunk rattling

When applying it, a few tools that will make the application process easier include:

  • Utility Knife
  • Roller
  • Hole Punchers
  • Heat Gun
  • Panel Tools
  • Rubbing Alcohol
  • Paper Towels

Heat guns are especially helpful if you live in a cooler climate. Please note that it is best to apply in warm or hot conditions. If it is cold, it will become stiff and the adhesive will not adhere to surfaces as well.

Applying sound deadener is similar in every vehicle:

  1. Begin by using panel tools to remove the interior panels and carpet to any surfaces that you will be applying the material to. This may require the removal of bolts, screws, fasteners/clips, and wiring harnesses.
  2. After removing the panels, you should make note of any components that would prevent the panel from going back on properly if the material covered it such as bolts, screws, fasteners/clips, moving components. electronic modules, and wires.
  3. Clean the surfaces that you will be applying it to. This is best done with rubbing alcohol and paper towels or a cloth. Test the rubbing alcohol in an inconspicuous area first before proceeding with cleaning the entire panel to ensure the rubbing alcohol does not harm the plastic. Any other cleaners, especially oil-based ones, may prevent the adhesive from adhering to the surface so be cautious in the selection of a cleaner.
  4. Take a few measurements of each location that needs treatment to ensure efficient use of the material.
  5. Cut it into the sizes you need for your application.
  6. Adhere the deadener to the location and use the roller to apply pressure. If you are working in a cooler climate, it may be necessary to use a heat gun to heat up the material and adhesive before laying it down.
  7. While laying the deadener down, do not forget about the areas you made note of at the beginning of the process. You want to make sure the panel goes back on properly and doesn’t prevent you from hooking back up any harnesses or moving components.

For locations that have lots of components, you can even opt to use a clear tracing tape:

  1. Place the clear tracing tape on the panel and mark where you will need to make cuts.
  2. Lay this clear tracing tape onto it and create a more customized cut.
  3. The hole puncher can be used to make cutting holes for bolts, screws, and fasteners/clips even easier.

Any surfaces within the sheet metal can have sound deadener applied to them too. Just be sure to take into consideration the location of the window as it moves up and down. It is not necessary to cover EVERY surface of each panel. Be smart about the placement,
