Virtually every car owner, especiallydomestic production, familiar with the problem of noise penetrating into the cabin through the bottom or arches. Some drivers do not try to somehow fight it, others, on the contrary, tend to make their car as comfortable as possible.
Until recently, the only solution wasapplication of noise and vibration isolation, which is a special bituminous mats. Glue on the bottom of them you need from the cabin, looking at it completely, on the arches - only from the inside, which, you see, is not very convenient and fast. In addition, the laying of such material requires its heating.
However, about five years ago the markets appearedan excellent alternative to them - liquid car noise insulation. Reviews of car owners show that it is not only more convenient to apply to body parts, but also much more efficient than usual "noise". What it is, what kinds of it are on sale and how to use it, we'll talk in this article.
Liquid sound insulation is a special tool,made on various bases (bitumen, rubber), designed to reduce noise and vibration in the cabin of 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 also used in combination with conventional bitumen sound insulation. In this case, the effect of sound and vibration absorption will be the highest.
Those owners of cars that have experienced on theirauto effect of liquid "noise", unanimously declare its high efficiency. Economical drivers here see a certain advantage, consisting in the absence of the need to spend separately on anti-corrosion treatment, and separately - on soundproofing.
In addition, any liquid car noise insulation has a number of advantages over conventional. Here are just a few of them:
We sell liquid soundproofing for the following products:
Let us consider in more detail what this product is.
Rubber bitumen mastic - a remedy consisting ofa solution of bitumen and rubber (rubber) with the addition of alkyd resins and plasticizers. The assortment of these products is quite wide, but none of them falls short of the ideal due to the final state of the dried solution. Unfortunately, such a fluid soundproofing of the car does not harden completely, which makes it more similar to an anti-corrosion coating. The most common rubber bituminous mastics in our markets are "Cord", "Cordon", "BPM-1", "BPM-97".
NoiseLIQUIDator - good vibro-absorbingmastic of Russian production, used mostly for arches, although it is also suitable for bottoms. It consists of two synthetic components: base and hardener, mixed in certain proportions immediately before the start of work. Can be used for dehumidifying ribbed metal surfaces: bottoms, ararok, rapids, etc. It is not recommended for application to plastic.
Apply by hand with a spatula. The time of hardening of a single layer is a day.
Nuxodol 3100 - pasty liquid sound insulationSwedish production. It has excellent soundproofing, vibration damping, anti-abrasive and water repellent characteristics. Can be applied to metal and plastic surfaces with a brush, roller or with a spray gun. Pre-drying - 10-12 hours, full - 1-2 weeks. After drying it takes the form of a solid polymer film. Excellent painted car enamel.
"Dinitrol 479" - the most popular andwidespread we have a sound insulation. Comments on its application are extremely positive. It is also produced in Sweden. "Dinitrol 479" combines three functions at once: protection from gravel, prevention of corrosion and noise insulation. Sometimes it is also called "liquid fenders", as it is often used to handle arches. Can be applied with a spatula, brush, roller. Total drying time is 12 hours.
Liquid sound insulation "Prime Anti-noise" is a universal tool that simultaneously protects the body from corrosion and reduces the level of noise coming from under the car.
It consists of white spirit, modifiedbitumen, perlite, synthetic resin, rubber crumb, aluminum and zinc powders, and corrosion inhibitors. The product is absolutely odorless and completely safe for health. It has high soundproof, anti-gravel and anti-corrosion properties. Sold in the form of an aerosol in cylinders. "Anti-noise" can be used to "blow out" hard-to-reach places (hidden cavities of doors, thresholds, spars).
If you decide to contact a specializedcenter in order to make your car more resistant to road noise, be prepared for the fact that you will be offered to choose the materials yourself.

And now let's talk about how to apply thismeans, as a liquid noise insulation, with their own hands. This is not such a troublesome occupation. First, you need to determine where it will be applied: on the inside or on the outside surfaces. Further, proceeding from this, choose the appropriate tool and make a calculation of its quantity. Better, of course, first to process the car from the outside, because inside it will be possible to make additional noise isolation though bituminous mats, although the means described above.
Before starting the work surface is necessaryWash thoroughly with hot water, then clean off the rust and degrease. Only after this, you can begin to apply noise insulation with a spatula, brush or spray. Excellent, if it is enough for several layers. In this case, apply a second layer only after the first coat has dried completely.
Before operating the vehicle, allow the product to dry completely. It can take 1-2 weeks, but it's worth it.
