Does Soundproof Paint Work?

Loud noises can be a nuisance in any home. Whether you want to limit distractions in your home office or keep loud sounds from waking up a baby, soundproof paint may offer a solution.

Instead of installing soundproofing foam or soundproof wallpaper, you can simply apply several layers of specialized paint to help block noises. However, before buying a can of soundproof paint, you should know how this paint works and how much noise it can block.

For a lot of people even something so simple as installing some noise reducing curtains can help dramatically.

How Does Soundproof Paint Work?

Soundproof paint works in several ways to help reduce noise from penetrating a room and helps keep noises from leaving the room.

The paint is made with a combination of materials, including small sound-dampening fillers and ceramic microspheres. These materials help create a heavy-bodied paint that creates a thick layer with each coating. The thickness of the paint offers a little bit of sound reduction.

The materials included in the paint also help give the dried surface a soft, speckled texture. This texture helps absorb sounds and reduce echoes in the room.

To use soundproof paint, you simply need to paint the walls and ceiling of the room. However, for maximum results, you may need to apply at least three layers of the paint.

It can be applied just like any other paint using either a brush or a paint roller. However I have never used in with a paint sprayer so you may want to test that before trying to cover a larger area.

Given that it is a lot thicker than regular paint you may not get the required results when using a sprayer as many commercial sprayers will call for the paint to be thinned before use. This is the opposite of what you want from noise reducing paint.

The best option is probably the roller. You can apply some very generous layers of paint with a roller.​ The thicker this paint goes on the better it will work.

Make sure to allow it to dry between coats for best results.

Soundproofing Paint Dampens Midrange Frequencies

Soundproof paint is not designed to provide a complete soundproofing solution for blocking all unwanted noises. The paint is primarily intended for reducing midrange frequencies. This includes low to moderate noise levels coming from outside the room, such as conversations at normal speaking levels.

The paint absorbs sounds, dampening the noise levels of outside sounds and reducing the amount of noise that travels out of the room. While the paint may help block conversations, it may not help you deal with louder sounds, such as power tools, barking dogs, loud vehicles, or noisy music.

Lower level frequencies ​such as the bass from music will not be dampened by noise reducing paint. The lower level frequencies have much longer sound waves and as such are generally harder to stop traveling through your interior walls.

Much higher level frequencies will also not be effectively absorbed by noise reducing paint.

Advantages of Using Soundproof Paint for Your Home

While soundproof paint is not effective at blocking loud noises, it does provide a simple option for helping to dampen some noise. You may use this in a room to help create a slightly quieter space.

Applying soundproof paint does not require as much work as installing a complete soundproofing solution. If you can paint a room, you can apply soundproof paint.

Another benefit of the paint is that you can apply it to any surface. Besides walls and ceilings, you can apply the paint to doors, closets, and shelving. In most cases, you do not need to apply a primer. Due to the thickness of the material, you can simply start rolling the paint onto the surface.

Disadvantages of Using Soundproof Paint to Block Sound

The main drawback to soundproof paint is that it may not provide the results that everyone is looking for. If you want to block louder sounds, you may need to use something a little thicker, such as soundproofing panels.

Some people are disappointed with the results, as they expect the paint to provide a more effective method of blocking sounds.

Another issue with soundproof paint is that you need to apply several layers to achieve maximum sound absorption. Most manufacturers of soundproof paint recommend that you apply at least three layers, which can increase the overall cost of using this paint to soundproof a room.

To be honest if you are planning on applying upwards of three layers of noise reducing paint then your money may be spent on better solutions such as sound proof panels or wallpaper. ​

You may also find that there is a limited number of colors available so unless you like to use plain colors on our walls you may not find the type of finish that you want.​

Should You Use Soundproof Paint in Your Home?

If you want to create a quieter space, soundproof paint may provide the noise absorption that you need. It is not the thickest material or the most effective option for soundproofing a room. However, the paint is easy to apply, allowing any homeowner to quickly add noise dampening to any room.

Keep in mind that the paint will not block louder sounds. A garbage truck outside the house or neighbors blasting music can still create a noise disturbance, even with multiple layers of soundproof paint. The paint is not intended as a complete soundproofing solution.

When you want to keep things just a little bit quieter, this paint may work for you. You may block the sound of neighbors talking at normal speaking levels or limit the sound of floors creaking through the house.

In the end, soundproof paint is a simple, cost-effective way to make a room a little quieter. However, you may need to use several coats to get quality results.

Blocking louder noises will generally require some better solutions.
