Ways to Replace Your Car's Sound Deadening
One convenient way to get rid, or at least reduce, the outside noise penetrating your car is to set up a sound deadening inside your vehicle. If you have already installed a sound deadening previously, chances are, it might already be worn out after a few years or so. To restore the ambience in your car, you can replace the sound deadening using a few simple tools.
Difficulty level: Moderate
Tools to be used:
- Dampening materials
- Contact adhesion glue
- Paint brush
- Measuring tape
- Razor blade
Step 1: Select which type of dampening materials you desire to use to dampen your car. There are mats, sprays, insulations, or sprays. The best practice is to use a combination of these materials, so that you can have maximum damping within your vehicle.
Step 2: Use dampening mats to increase the weight on the panels, since the panels have a tendency to vibrate, resulting in annoying noise. If they are pressed enough with a heavy or strong material, then the vibrations can further be reduced.
Step 3: Install the dampening mats in between 2 of the door panels that are near each other. This will minimize the vibrations within that space in the middle of the 2 door panels.
Step 4: For minimized engine noises, such as rattling, you can place the dampening mats inside the engine compartment. Since the mats come with metal foil backing, you don't have to worry about the heat. These mats have high heat resistance, so they can stick around the engine area without burning.
Step 5: Use a contact adhesion glue to stick the mats onto the engine compartment. You can find this glue at any auto repair shop. If you want to obtain the glue without any hassle, simply purchase one online and have it delivered straight to your home.
Step 6: If you're using a spray or a foam spray, you can simply fill the small spaces in between your car parts, where noise usually occurs. Since the sprays expand as they cure over time, these will eventually push against the nearby panels. This then results in a sound deadening joint that distributes and disperses the vibrations.
Step 7: If you're using insulation for sound deadening, make sure you measure the door panels and carpeted areas first. This will give you an accurate trim of the dampening materials that you're going to use.
Step 8: Cut the insulation or matting according to the measurements of the surface you want to sound deaden. Ensure that you pull the carpeting from the car body before continuing with the next step.
Step 9: Paint some contact adhesion glue to the car body where you want to install the dampening mats and insulation. Then, put the damping materials on top of the glue. Press firmly to make sure it sticks properly to the surface.
Step 10: Spray some more foam or spray-on sound deadening material in each of the crevices, if needed. Finally, let the glue and spray-ons cure or dry out, based on the directions on each of the materials.
