Almost every car owner, especially of domestic production, is familiar with the problem of noise penetrating the cabin through the bottom or arches. Some drivers do not try to deal with this at all, while others, on the contrary, strive to make their car as comfortable as possible.

Until recently, the only solution was the use of noise and vibration isolation, which is a special bituminous mats. You need to glue them on the bottom from the passenger compartment, disassembling it completely, into arches - only from the inside, which, you see, is not very convenient and fast. In addition, laying such material requires warming it up.

Liquid soundproofing

However, about five years ago, a great alternative to them appeared on the markets - liquid car soundproofing. Feedback from car owners shows that it is not only more convenient to apply to body parts, but also significantly more effective than the usual "shumka". What it is, what types of it are on sale and how to use it, we will talk in this article.

What is the essence of liquid soundproofing

Liquid noise insulation is a special product made on various bases (bitumen, rubber) designed to reduce noiseand vibrations inside the car. In addition, this product has excellent protective properties that prevent corrosion of body elements. It can be applied to both internal and external surfaces of the bottom and arches, and can also be used in combination with conventional bituminous soundproofing. In this case, the effect of sound and vibration absorption will be the highest.

Do-it-yourself liquid soundproofing

Let's take a closer look at what this product is.

Rubber bitumen mastics

Rubber-bitumen mastic - a product consisting of a solution of bitumen and rubber (rubber) with the addition of alkyd resins and plasticizers. The range of these products is quite wide, however, none of them falls short of the ideal due to the final state of the dried mortar. Unfortunately, this liquid car soundproofing does not completely harden, making it more like a rustproof coating. The most common rubber-bitumen mastics in our markets are "Kord", "Kordon", "BPM-1", "BPM-97".

NoiseLIQUIDator

NoiseLIQUIDator is a good Russian-made vibration-absorbing mastic, used mostly for arches, although it is also suitable for the bottom. It consists of two synthetic components: a base and a hardener, mixed in certain proportions immediately before starting work. Can be used for noise reduction of ribbed metal surfaces: bottoms, ararocks, sills, etc. Not recommended for application on plastic.

Applied by hand with a spatula. The hardening time of one layer is a day.

How to make liquid noise insulation with your own hands

And now let's talk about how to apply such a tool as liquid sound insulation with your own hands. It's not that much of a hassle. First you need to decide where it will be applied: on internal or external surfaces. Further, based on this, select the appropriate tool and make a calculation of its quantity. It is better, of course, to treat the car from the outside first, because inside it will be possible to make additional sound insulation even with bituminous mats, even with the means described above.

Before starting work, surfaces must be thoroughly washed with hot water, then cleaned of rust and degreased. Onlyafter that, you can start applying sound insulation with a spatula, brush or spray. Well, if it is enough for several layers. In this case, apply a second coat only after the first one has completely dried.

Allow the product to dry completely before using the vehicle. It may take 1-2 weeks, but it's worth it.

Helpful tips

In preparation for self-treatment of the car with liquid soundproofing, use these tips:

  1. Don't buy cheap materials from obscure outlets. Instead, visit a specialized store, where you will also be advised on the correct use of the product you have purchased.
  2. Pay maximum attention to washing and cleaning the surfaces to be treated - only in this case your work will give a good result.
  3. Before processing, remove the wheels of the car and isolate the hubs with pads with polyethylene to prevent mastic from getting on them.
  4. Do not process at temperatures below 10 oC - the mastic will harden much longer.
  5. Never mix different products.
  6. Do not apply in a thick layer. It is better to make several layers, waiting for each of them to dry completely.
  7. If the processing seems impossible to you, contact a specialized service center.
