How to soundproof a car on your own and avoid fatal mistakes?


Good afternoon dear motorists. Today, we want to tell you how you can make a noise in a car on your own and avoid mistakes.

Do-it-yourself noise isolation or in a service center? Each owner thought about how to make soundproofing. Someone is disturbed by the noise of the road, someone is annoyed by the noise during the rain, and someone wants a high-quality sound of music in the cabin, not the engine. Also, on the network, in addition to rave reviews, you can find a lot of negativity associated with the fact that the Shumka does not work. It is in order for you to succeed that we offer you to get acquainted with our article-instruction.

The main problem that the owner may face — improperly performed soundproofing of the car — is corrosion and rotting of the metal. Such consequences can occur with poor-quality rolling of the vibratory material. In the voids between the adhesive layer of the material and the metal surface, due to the difference in ambient temperatures, condensate forms, which over time will contribute to corrosion and further destruction of the metal. To avoid this, the vibration absorber must be mounted on a previously cleaned and degreased metal surface, carefully rolling the material with a roller.

  1. The surface to be treated must be clean, free of rust and rot, and must be degreased before applying the material. If rust is present on the metal, it should be removed. Also, rust can hide under the paint that has come off the metal. It looks like a bubble. In this case, the paint must be removed and the area around the bubble formed to be cleaned in order to further prevent the formation of rust.
  2. High-quality bonding of the material. Sheets of vibration isolation must be rolled very strongly to avoid the formation of air bubbles between the material and the metal.
  1. The correct sequence of materials. It is necessary to observe the phasing of the application of materials. It is impossible, for example, to first glue soundproofing material to the metal, and then sheets of vibration isolation on it. There will be no effect from this, only negative results. First, it is necessary to roll the vibration isolation sheets, and then glue the necessary soundproofing materials. With noise and vibration isolation, the mass of the material should be taken into account. The material must be chosen in such a way that the principle of reasonable sufficiency is respected.

And the fourth, important stage, is the performance of work in the heat. Noise and vibration isolation work must be carried out either in the warm season or in a heated garage. Usually it is recommended to work at a temperature of 20 degrees.

There are two options for selecting the noise-vibration isolation zone:

  1. By time and complexity (first, simple zones are processed in order to understand the principle and gain experience, and then move on to more complex ones)
  2. By noise (first, the loudest zones are noisy to feel the effect immediately, and then all the rest). Which option to make the car noise is up to you!


So, we come to the first layer of sound insulation. We take vibration isolation (two Russian brands Shumoff and Smartmat are represented in our store) and glue it to a fat-free surface. The thickness of the mastic and its density may vary — depending on the tasks that you want to solve.

We check carefully that there are no bubbles anywhere. Bubbles are the worst thing that can happen in the process of self-soundproofing a car. Bubbles are a direct way to rust and rot your car. Agree that this is not what you would like to see. Do-it-yourself noise isolation is not a very complicated process, the main thing is to pay attention to such details.

Next, you need to take a special roller for soundproofing. At Das4you, we have two tools for rolling in — Metal roller for rolling in vibration isolation 35 mm elongated and inmetal roller for rolling vibration isolation 35 mm short

Unfortunately, no matter how much you want to, you can’t fully press the sound insulation with your hands. For reliability, it must be rolled. Manufacturers have been making corrugated patterns on foil for quite some time now. If it has become flat, then you have rolled the vibration well.

If there is a clear scheme of actions and consumables, the availability of a tool, then the work will be done in the shortest possible time and with the highest quality, and most importantly — with pleasure!
