Does soundproofing paint really work? (Reviewed)

When I first heard of soundproof paint, it was quite hard for me to digest that paints can also help in soundproofing. I hope that the same thing would have happened to you, but have you ever wondered how soundproof paints even work or does soundproof paint really work?

Well, I was very curious to find the answers to all these questions and fortunately, I did find all the answers by asking some professionals and some of my friends who actually used the acoustic paint. So, in this article, I will tell you everything you need to know about soundproof paints and I will also share my experience with acoustic paint.

Does soundproofing paint really work?

The answer is a big YES, soundproof paints do work as a soundproofing material but I would say it’s more of a sound deadener rather than a sound blocker. It prevents the reflections of noise waves and helps in deadening the echo inside the room. Soundproof paints are capable of reducing low to mid-range frequency noises.

Reducing high frequency or loud noises like Dog’s Barking, traffic noises, banging of hammer, lawn mower’s noise or passing by train horn’s noise does not come under the job of soundproof paints. 

Whereas acoustic paint works well in reducing the noise if your neighbour creates noise by shouting or talking loudly. We performed an experiment on soundproof paint using low to mid-frequency range noises. Here are the results:

S.No.Noise from sourceNumber of Coats (paint)Noise after coating

2.40 DB236.29 DB
40 DB333.97 DB
4.60 DB159.25 DB
5.60 DB258.36 DB
6.60 DB356 DB
Data from our own research

These results clearly verified that as we increase the number of coatings, the level of sound reduction also increases and the room becomes more soundproof. Also, the paint was more effective for low-frequency noises as compared to the higher ones.

Hence, it is very clear that soundproof paint works but it’s more effective as per the sound deadening perspective rather than sound blocking. Acoustic paint can be used for both internal walls as well as the external walls of your house but I would rather use it for the wall or ceiling which needs to be soundproof.

Soundproof Paint vs Regular Paint

Because of the hazardous materials used in the manufacturing of most of the paints, it becomes a very common question to ask if soundproof paint is safe?

And if it’s safe, how is it different from regular paint?

The contents involved in manufacturing the paint is the key difference. Let me tell you in detail, acoustic paints contain an organic compound called Latex which is responsible for the insulation properties of soundproof or acoustic paints. 

Not just acoustic insulation, soundproof paint comes with thermal insulation properties as well. The acoustic paint will trap the heat inside the room in winters while in summers it doesn’t allow the external heat to enter inside.

Unlike regular paint, acoustic paint contains regular fillers that are responsible for the soundproofing properties of the paint. Because of this uniformity in acoustic paints it results in absorbing echos and providing better sound insulation. Also, higher thickness of soundproof paint is also responsible for better acoustic properties.

Pros and Cons of Soundproof Paint

Everything has its own pros and cons, so does the acoustic paint. Let’s have a look at both of them.

Pros:

  • Inexpensive

Acoustic paint is quite a cheap option for soundproofing compared to other options like gazed glasses and solid doors. You can get one gallon of acoustic paint for around $45 – $50.

  • Dual Insulation Property

As we discussed earlier, soundproof paint doesn’t just provide insulation from sound but also offers thermal insulation. Be it trapping heat inside the room in winters or blocking the external heat entering the room in summers, acoustic paint will do both for you.

  • New Look

Well, I consider it a pro because I love designing my house and playing around with the architectural stuff. If you’re one like me then you’re gonna love the new design of your walls and the ceilings.

  • Reduces Echo

Soundproofing is not just about insulating or blocking the sounds, it’s also about absorbing the external or internal noise in the room. The uniformity of acoustic paints helps reduce the echo which leads to a quiet room.

  • No need to paint the whole house

The best part about soundproof paint is that you don’t need to paint the whole house, either you paint a wall or ceiling which receives most of the noise or you can paint the rooms that receive loud noise.

Most of us need soundproofing for video recording or audio recording purposes. In such cases we don’t need to soundproof the whole house, just paint the room you work in and you are done. You can paint the outside walls if your room is beside a roadway and receives a lot of loud noise.

  • Non-Toxic

As we discussed earlier, Soundproof paints are non-hazardous unlike most of the regular paints. Some people are actually allergic to the toxic ingredients of the paint so if you’re one of them then don’t worry, acoustic paints will not harm you.

Cons:

  • Limited Color options

Soundproof paints come with a limited color options and you will have to select one from those colors. For me it’s not really a con as soundproofing is a much bigger deal for me, but if you are a choosy person then you might have a hard time selecting the right color.

  • Time and Effort

Obviously, painting a room or a ceiling would require both time and effort, and if you are not one of those creative people who love to do crazy DIY stuff then you’re gonna have a hard time again. DIY things would definitely create more chaos, so, you’ve one other option to hire a painter but it would add up the labor cost as well. Whereas, other soundproofing options like acoustic panels and MVL sheets are very easy to install.

Where to buy soundproof paint?

You can easily purchase acoustic paint through online retailers like Amazon, Walmart and HomeDepot. Also, you can easily find soundproof paint in your local paint stores.

Many retailers also sell regular paint as soundproofing paint so I would recommend purchasing a branded paint only, or if you are buying any non branded paint then check the ingredients involved in the manufacturing of the paint. 

Soundproof Paint Cost

Well, a single gallon of soundproof giant would run you through $35 – $60, for instance, one gallon of paint can be used to paint up to 400 square feet of area. 

But for soundproof paint we add minimum two layers of coating so the area would reduce to half, and if we apply three layers then it would decrease further.

How to make the best out of Soundproof Paint?

There are some other things you should definitely try with soundproof paint for creating a better soundproof space. Let’s discuss each one of them one-by-one.

  1. Add at least 3 layers

“Thicker the paint, the more effective it is”. Adding at least three layers creates a uniformity that helps in better sound insulation. Especially, focus on the corners and the joints of the wall, a thick coat should be created at such critical points.

This thick surface will prevent the echos and the sound reflections through the walls or the ceiling, hence, making the room more soundproof.

  1. Add Furniture

It is a very basic concept that we learn at our schools, as the number of objects in a room increases, the sound reflections and echo effect decreases. So, adding furniture beside the painted wall would increase the effectiveness of soundproofing.

  1. Seal the holes before painting

Before painting the wall, make sure you fill all the holes and cracks in the wall. It would prevent that unnecessary noise from entering through those holes or cracks. You can apply green glue or Caulking for filling these holes and cracks.

  1. Soundproof other parts of the room

At last, soundproof all the parts of the room like Door, Windows, and Floor. You can use household items like rugs, blankets, and curtains for the same purpose.

Soundproof Paint Alternatives

MVL sheets are a great way to soundproof walls, ceilings, doors or even ducts. A 4 x 10 feet Mass Loaded Vinyl sheet would cost you around $120. You can purchase smaller sheets as well, depending on the requirements.

Soundproof panels work very well with walls, the part thing about these panels is that they are easy to install. On average, these acoustic panels would run you through $50 – $60 per unit.

  • Soundproof curtains

Also, known as acoustic foam tiles are very effective and at the same time really inexpensive. For around $50 you can get a decent quantity of these tiles.

Conclusion

Soundproof paint works really well as a sound deadener but its job as a sound blocker is not very good. However, at such a cheap cost it’s quite an affordable option. 

If you are facing problems with low to mid-frequency noises then acoustic paint is gonna help you a lot. Moreover, reducing echo and bouncing of sound through walls is also a function of soundproof paint.
