Does Soundproofing Paint for Walls and Ceilings Work?

One of the biggest questions in the world of soundproofing methods is the one about soundproofing paint.

Does it work?

Well, it depends. Basically, it works great at certain noise levels. And not every paint works the same.

Since my house needed an arrangement, painting, and soundproofing, I figured it out and gave it a try.

Long story short, this noise reducing paint did the job.

No matter how strange it sounds, it can work in certain situations.

For example, if the noise that is coming from the other room is not that loud, then why would you waste money on some foam panels, blankets, and curtains when a simple soundproofing paint can do the job just fine? There are other soundproofing methods you can try.

Simply put, the soundproofing paint is a two-in-one solution to your problems.

It will simultaneously decrease the noise level and help you redesign your room and positively impact sound transmission.

Nevertheless, there are a lot of benefits coming from this paint.

It’s true, it demands a bit of your time and effort, but the whole procedure is quite worth it as noise reduction can be significant in the end.

Now, let’s learn some basics about acoustic paint, when to use it, how does it work, and finally, how to achieve the best results with soundproof paint on a solid surface.

Basic Things to Know about Soundproofing Paint 

First of all, before you decide to go with soundproofing paint, you should know a few things.

The sound deadening paint can be used on any surface on which the regular paint can be used.

Being interchangeable, it’s quite useful to have it on your walls as a sound reduction solution.

Furthermore, you do not need to paint the whole house with it. Phew!

If you have some critical spots that need more soundproofing than others, then you can simply paint those spots with soundproofing paint for walls and others with a regular one.

As I mentioned earlier, but not detailed, the soundproofing paint will be effective to a certain noise frequency and work with specific sound waves.

If there are some savages next to you, making a really loud noise, then this paint will probably be useless.

For the best possible outcome, use the sound dampening paint at mid-frequency noise.

Those frequencies are mostly conversations between people.

To give you a better insight of this noise, it’s basically the regular talking sound level.

Therefore, the soundproofing paint should be used if you are hearing (not that loud) sound passing through your walls.

In other words, trying to reduce the noise with acoustic paint from your neighbor’s dog or his loud music will most likely fail.

One of the most important things that you should be prepared for is to paint a few layers of coating with acoustic paint.

Let me translate: be prepared to spend some extra money as you will need more than 3 layers of this soundproof paint in order to achieve the best results.

Therefore, it requires a bit more time, money, and effort. But all of these things will probably be necessary while pulling out some alternative methods and soundproofing materials.

How Does Soundproofing Paint Work?

The thicker the material is the better soundproofing you get. That rule is simple and clear. And it applies to soundproof paint as well.

In order to answer the question of “how does it work”, I need to give you an insight on how thick this soundproof paint is.

The thickness of this soundproof paint depends only on your preferences.

In most of the cases, you will need at least 3 layers to reduce noise from a normal conversation, from the apartment next to you, in half.

Basically, one layer is enormously thick for the sound dampening paint.

Soundproofing paint for walls is heavy bodied, made of ceramic microspheres and special sound absorbing fillers.

This will drastically increase its absorbing sound power and reduce echo.

It is water-based and it will easily prevent the sound from bouncing around in your room.

Soundproofing paint, or some may call it- the deadening paint will effectively dampen tinning noise and ringing in all metal structures.

Acoustic paint is a great fighter against the noise on 2 different levels.

Firstly, it will reduce the noise by absorbing it. The noise from inside your room (echo for example) will be minimized.

Also, the sound that is going outside of your room will be prevented from disturbing your neighbors.

As you may know, you can use some furniture or objects in order to prevent the echo.

These pieces of furniture will prevent the noise bouncing from flat surfaces and reflecting to other directions.

Related to that, sound dampening paint acts as a soft and thick surface which will prevent that sound from bouncing and protect your room from the echo effect.

On the whole different level, this sound absorbing paint will drastically decrease some reasonable noise that comes into your room.

Preferably, you should paint over all the impact walls- those at the noise impact. If not, you risk achieving the minimal effects.

The sound dampening paint is non-toxic and environmentally friendly.

It’s basically the same in this matter as regular paint. There is only one difference- this sound dampening paint acts like a sound deadener.

Also, you can apply it in several different ways.

You can use roller or spray to fasten up a procedure a bit, or you can simply go with a brush, or a hopper spray gun. It works both for exterior and interior use.

Since you will need a few layers at least, I would personally recommend this roller as it has shown as the fastest performing tool.

This kind of paint in most cases can be easily cleaned.

All you need to do is grab some water and soap, and the paint will be clean in no time. We like that!

Of course, if you are worried about the design of your room, you shouldn’t be.

This acoustic paint, as a regular one, comes in different colors and shades.

You will be able to match it to your room’s design easily.

Where can you use soundproof paint?

Simply speaking, you can put sound reducing paint wherever you feel the most vulnerable to the noise.

Basically, this sound deadening paint is used on the interior surfaces.

Other than walls, and ceiling, you can use this paint on wood and metal, as well as on primed drywall.

Again, make sure that you cover whole walls (for example) as it will increase the absorption by a lot.

Also, you may cover some crevices with it and seal the holes that release the noise.

What are the benefits of soundproofing paint?

As you have already seen in this article, sound absorbing paint will decrease the noise of some normal frequencies up to 30%.

Nevertheless, there are few more benefits from using acoustic paint.

Soundproofing paint is quite thick material.

Therefore, depending on the coatings and layers put, it can act as a great thermal isolator.

Since I have this paint in several rooms, I’ve managed to record the difference in the temperature before and after putting it on my walls.

The results were more than amazing. I’ve noticed several degrees difference on average.

By the way, here are some of the best quiet air conditioners if you're interested.

Finally, you can use this method as a solution to several problems.

It’s a quite cheap method and you can do the job of soundproofing and painting simultaneously.

Of course, there are limited color options for this paint but I’m sure that you will manage to fit the wanted color anyway.

How to achieve the best results with combined methods

Basically, if you want to reach some better results, you can combine sound deadening paint with some of the easiest soundproofing methods, or even using household items.

Namely, if you wish to block the noise even more, then, after painting, you can simply put a large piece of the furniture up against the walls such as bookshelves as an additional layer of noise defense.

That will also reduce the echo to 0, and prevent the noise from molesting your neighbors.

Furthermore, if your rooms have windows and walls, you should consider soundproofing them as well.
