Best Sound Deadening Sprays for Cars
Reviews of the Best Sound Deadening Sprays for Cars
We’ve selected some of the highest quality sound deadening sprays that are appropriate to use in any make and model of car. These products have all stood the test of timing, received thousands of positive recommendations, and comprise some of our personal anti-sound favorites.
1. LizardSkin 50115 Sound Control Ceramic Insulation
- Country of Origin : United States
- Fit type: Vehicle Specific
Lizardskin 50115 is one of best sound barrier sprays that is safe to use on a variety of mechanical products. This paint-on, acrylic insulation is dedicated to dampening sound caused by vibration as well as providing an extra layer of thermal insulation to your vehicle.
If your vehicle makes a “tin can”, hollow sound, Lizardskin acts effectively to deaden any source of resonance. Though it may not wholly eliminate road noise, you will notice a significant reduction right away after applying the painted solution.
Additionally, Lizardskin is advertised for its ability to target sources of noise that include wind whir, vibration, roughshod road, and the “hollow” noise made by older cars.
Many customers prefer the Lizardskin spray since it looks much better than installing anti-vibration mats into their vehicle. The black paint blends in well with most plastic footbeds of any make or model of car. Additionally, prep and customization is much easier with the paint than with traditional mats.
The one slight drawback of the Lizardskin product is that, once applied, it can be very difficult to get the layer off of accidentally painted areas. Once the coat dries within twenty minutes of application, it can be extremely difficult to cause the layer to split from the painted surface.
However, other customers believe that this is actually a good aspect of the product, since it means it has extremely high adhesion to surfaces that allows the Lizardskin to achieve noticeable sound reduction.
2. Design Engineering 050220 Boom Mat Spray On Sound Deadener
- Reduce unwanted road noise and vibration, even in hard-to-reach places
- Won’t crack or chip; helps prevent rust
Guaranteed to reduce unwanted road noise and vibration, the Design Engineering spray on deadener can reach even the most hard to access places with a very precise spray tip. This spray will not crack or chip, helping to prevent rust over sensitive metal components and the bed of the car.
In just under six hours, you’ll be able to cleanly apply and let the spray on dry in the interior of your car. Many customers opt to apply several coats for even higher degrees of sound deadening.
Additionally, the spray on paint is very safe to use. The non-toxic formula is built to withstand temperatures of up to 300 degrees Fahrenheit, making it ideal for a wide range of mechanical tasks.
Once applied, the spray will not only reduce sources of aggravating noise, but will act to wick away sources of moisture in order to improve the longevity of your vehicle’s interior. Through eliminating squeaks, rattles, vibrations, and unwanted engine noises, the Design Engineering spray achieves effective thermal insulation and improved user safety.
Some customers are frustrated that the spray takes a very long time to dry, even in hot, desert climates. However, the rubberized undercoating that constitutes the spray needs time to create the most effective seal along the surface it’s painted on.
3. 3M Professional Grade Rubberized Undercoating
- MULTI-PURPOSE UNDERCOATING may be applied to cars, truck and recreational vehicles
- SOUND DEADENING PROPERTIES help reduce road noise
Completely corrosion, water, and salt resistant, the 3M professional spray is a multi-purpose tool that protects your vehicle against all sorts of unwanted sources of degradation. This spray is suitable to be used on cars, trucks, and recreational vehicles in order to reduce all sources of noise and unwanted vibration.
The rubberized undercoating of the 3M creates a texturized finish after application, helping to resist all causes of chipping, abrasion, exterior rusting, and weathering all in one go. Many users state that one coat is sufficient to provide all of these benefits, yet it is recommended to apply at least two coats between drying periods.
Additionally, the spray can be used to service car undercarriages in addition to protecting wheel wells, fenders, quarter panels, and much more. The rubber will help to insulate the vehicle bed from sources of noise, whether it’s from the road or the engine.
Many customers believe that using the 3M spray has helped them cheaply extend the service life of their vehicle, in addition to cutting out aggravating sound from the cabin. Users should be aware that one can is not sufficient to cover a whole vehicle – in fact, it may take between 6 to 10 cans in order to coat every component. Keep in mind this refers to coating the entire frame and underbody of the car.
4. GT Liqui-Damp Liquid Car Sound Deadener Kit
- Package Includes 1 Gallon GT Liqui-Damp, installation kit consisting of Easy to follow Installation, Application Brush, Degreaser, GT MAT Decals, Disposable Gloves, and Toll Free Tech Support
- GT Liqui-Damp Sound Deadener is a water-based liquid sound-dampening product that is non-toxic, non-hazardous, and non-flammable that may be applied by brush, trowel, or spray gun. GT Liqui-Damp air dries to the touch within 2 hours and fully sets in 4-6 hours. A standard application coat is approximately 32mil thick.
The GT Liqui-Damp kit generously provides 1 gallon of paint-on insulation material, one application brush, one degreaser, GT MAT decals, disposable gloves, a user manual, and toll free tech support contacts.
This water-based liquid is renown for its high degree of safety: the liquid solution is completely non-toxic, non-hazardous, and non-flammable. You can apply the solution using a brush, trowel, or spray gun without needing complicated safety materials.
Within two hours, the solution is dry to the touch and you’re able to add another layer. The whole liquid layer should then fully set within four to six hours.
Through covering and adhering effectively to just about any surface, the solution is perfect for rough surfaces, grease free metallic panels, and even corroded car underbody components.
Completely resistant to abrasion and chemical corrosion, the painted surface can be painted on directly after application. Even more interestingly, the water based coating dries to a very light, ‘barely there’ tan coat when completely cured.
One gallon jug is sufficient to cover approximately 75 square feet at 32 milliliters of thickness, making it very suitable for sound reduction and thermal insulation purposes.
Many customers buy this product along with the GTMAT in order to cover large, corroded holes in the body of their car or particular car components. Thankfully, the manufacturers have provided extensive online video tutorials and documentation about how to effectively use the product for sound deadening purposes.
Is your vehicle hopelessly noisy? Can you barely hear the stereo above the sound of wind whir, road noise, or unwanted engine noises? If your vehicle is on the older side, the noisiness of the cabin will only get worse until you decide to do something about it.
Fortunately, there are so many effective sound-deadening materials that are non-toxic, robustly tested, and completely wear-resistant for use inside your vehicle’s cabin.
Recently, many people have become curious about spray and paint-on materials that can both insulate and provide convenient sound-dampening. Though anti-vibration mats are hailed as the “end all be all”, spray on solutions may just give major mat brands a run for their money.
Spray On Sound Deadening versus Anti-Vibration Mats: What’s Better?
Before you opt for spray on solution, you should know that they have distinct pros and cons as compared to the standard anti-vibration mat.
Anti-vibration, sound deadening mats are typically made of one-inch thick rubber that can adhere to the surface of the vehicle. Time and again, mats have proven very effective against virtually all types of vehicle disturbances.
On the other hand, spray and paint-on solutions are a wet product that can be applied directly to any component of your vehicle. These paints will typically dry within two hours and you can layer as many coats as you want for ideal sound protection.
Typically, spray-ons are made from liquid rubberized seal that will automatically create perfect adherence to any surface. Sprays can reach very hard-to-access areas that make them ideal for sealing small abrasions and holes.
By contrast, mats often need to be “rolled out” once applied in order to make sure no air bubbles have been missed. On occasion, even expert appliers may leave behind irritating gaps that make the whole vehicle more prone to noise disturbance.
Additionally, sprays may boast features like anti-corrosion and water wicking that mats just can’t match. Sprays are often suitable to be sprayed on the entire underbody of the car, as well as the cabin, in order to improve the longevity of the vehicle.
Despite this drawback, many believe that mats provide better noise cancellation overall. Ultimately, mats are thick enough that – when applied properly – absorb nearly every source of unwanted vibration that causes noise.
However, this doesn’t mean sprays aren’t useful. Often, customers use sprays in tandem with mats in order to seal their vehicle as effectively as possible against any noise disturbances.
