Best Sound Deadening Sprays
Below I have put a small list of the top performing sound deadening sprays. Usually you cannot find these quality brands in stores, which makes them a very popular buy online. I have personally used some of the lower quality stuff you find at “auto stores” and never have been impressed, until I used products from reputable companies.
Usually with these noise reduction sprays you are going to want to apply many coats that are thin to achieve a nice thick Finnish. Don’t worry most of these sprays dry pretty quickly as in a few minutes and are ready for another coat right away. Some of the coatings come in cans that you can put in your own paint sprayer, but I would recommend getting a different nozzle, because some of this spray on sound deadener can be pretty thick and clog up normal paint spraying nozzles.
As I mentioned, this spray is sometimes used on the inside of dryer and wash machine panels and even computer panels. This is ok because most of the pints are nontoxic and dry hard. They also have the benefit of keeping moisture out where moisture is not wanted. Sound deadening spray can be applied to aluminum, steel, fiberglass, wood and poly type glass.
Here are some manufacturers of roll on and spray on sound deadener:
These rubberized sound deadening supplies come in spray cans that cans that can be sold in retails stores throughout the world. Its very common. You find that these are used in auto shops a lot to actually protect against rust and wear after a repair has been done, they work perfectly for this because of their anti-rust components.
Probably the most common place that you can go right now to see an example of sound deadening spray is in the trunk of your car. Peal back the lining carpeting of the trunk and you will probably notice this thick black material that almost looks like tar. This is the spray on or roll on sound deadening. This serves a couple of purposes. To not let the sound of the rear speakers out of the car and as well as keeping the road noise out of the trunk, where it can be amplified and spread inside the cabin of the car.
