Does Soundproof Paint Actually Work?


This is one of the most commonly asked questions on the internet because most of us are looking for cheap, easy soundproofing solutions. Even though there are several other soundproofing options out there, the whole idea of paint blocking sound just seems too good to be true. Well, does soundproof paint actually work?

The answer is yes, soundproof paint is quite effective in reducing the low-level faint noise. However, for high-level loud noises, it is not very useful, but you can combine it with any other proper soundproofing technique to get the desired result.

Let’s discuss everything in detail. But first, let us analyze the most common questions asked about soundproof paints.

The Most Common Questions About Soundproof Paint

What Is The Difference Between Regular Paint And Soundproof Paint?

We have all thought about this before, right? Soundproof paint is much thicker than ordinary wall paint. The reason is that soundproof paint consists of a combination of ceramic microspheres and sound-absorbing fillers.

These fillers work as a barrier to block low-level noises – faint sounds- that can be distracting especially when you are are trying to concentrate.

These constituents make the soundproof paint very thick. As a result of this increased thickness, when noise hits where the paint is applied, it is absorbed. So, how does this work?

How Does Soundproof Paint Work?

I won’t go into much of the technical stuff, but just some necessary details. To absorb sound, soundproof paints have been infused with fillers that have sound-absorbing properties. These fillers contain thermacel- which are airtight pockets with soft pigments in them. These pigments act just like the suspension of a car; they wobble and absorb the sound waves that hit them.

Because these pigments are just too small, they can only absorb mid-frequency sounds and not louder sounds. If you are having trouble with, let’s say with a loud TV or road noises, the soundproofing paint is unlikely to make a significant difference. However, if you combine this technique with any other soundproofing option -like drywall-, you can get some great results.

Do Soundproof Paints Work?

So far, I think the answer is clear; soundproof paints work, but only to a certain extent. Its efficiency depends on the level of noise, which should not be very loud for the paint to soundproof it completely.

Let me just give you a few examples of this. Here are a few scenarios in which a soundproof paint can help reduce to noise:

  1. If you are a light sleeper, and you get disturbed by the faint murmuring of the neighbor next door.
  2. When your baby wakes up because of low-level noise.
  3. If your neighbor complains about your late-night phone conversations.

In these cases, the noise level is quite low, but can still disturb your peace. If that’s the case, you can use soundproof paint for an effective result.

However, in these specific scenarios, soundproof paint might not work. Here are a few examples:

  1. Close traffic near your apartment. Here is an article if you want to soundproof your home from street noise
  2. The neighbor’s dog barking. you can check out an article on soundproofing a dog crate and kennel
  3. Someone running upstairs or moving the furniture. You can check out my comprehensive article on soundproofing a ceiling.
  4. Your brother playing his drums. Click here to see my exclusive article on soundproofing a drum room.

As you see, these noises are too loud for soundproof paint to reduce effectively. Therefore, I would suggest you don’t use it for any high-level noise. You might put on several coats of a soundproof paint, and it still won’t work. However, if you combine a layer of soundproof paint with any other techniques, you will get amazing results!

Soundproofing Methods To Combine With The Application Of Soundproof Paint

I have emphasized throughout this article that soundproof paint alone cannot fix your high-level noise problem. However, there are some easy and low-cost techniques that you can combine with the paint, which will surely help in reducing noise effectively. Let’s have a look at these techniques

1. Adding Up The Furniture

One of the basic principles of soundproofing is that mass blocks sound. This is a noteworthy fact about soundproofing! Proper furniture placement can reduce noise significantly!

For example, you can fill your bookshelf with books and place it against the wall shared with your neighbors. This action will add mass to the wall, preventing noise from passing through. Similarly, you can hang large frames, mirrors, or other decorative materials on your wall to add up to its thickness, and also reduce noise.

You can even place a sofa against the wall shared with your neighbors to overcome a significant amount of noise coming from the other side. Hanging plants around the corners is another excellent tip that doesn’t even require so much money. Aren’t these techniques just great?!

2. Cover The Wall With Panels

Wall panels for soundproofing

As we discussed in the previous section, the thicker the wall, the more noise it will absorb. That is why, if you install a soundproof panel on the wall, and then, cover it with the soundproof paint, it will make an enormous difference!

Using panels to cover the wall might seem like a tasking job, but actually, it is straightforward! You just have to cut the panels according to the size of the wall and screw them into the wall. Then, you can cover the wall with good soundproof paint, and you are good to go!

Coming to the types of panels, you can either use a simple plasterboard panel or a specially made soundproof panel. The kind of board to use depends on your budget and how much noise you want to reduce. My recommendation would be the Rhino acoustic panel that has a very high density and is perfect for soundproofing walls.

Another good option is the TroyStudio acoustic panels, which come in the form of a 6 pack dense and thick panels. Here is the Amazon link for further details.

3. Weatherstripping

Weatherstripping

Weatherstripping can be quite helpful in soundproofing the windows and doors, which can be the primary source of noise entering into your room. I have recommended this in a lot of my articles because it is a cheap and easy way to prevent sound from passing through gaps on your door and window frames.

Cloudbuyer weather stripping tape has got some fantastic reviews, and you can get it at a very cheap rate on Amazon. You can combine this technique with the soundproof paint to significantly decrease noise.

4. Thick Curtains

Soundproof curtains

The idea is the same as discussed earlier. The thicker the curtains, the more sound they will absorb. Although any thick curtains will tend to reduce the noise, for the best results, I would recommend you to get the Moondream sound insulation curtains. They are available in a lot of different colors, and you can easily purchase them from Amazon.

Simply get these curtains for your doors and windows and combine with the soundproof paint, and you will notice a significant difference in noise reduction.

5. Seal All The Holes And Gaps

 

Sealing holes and gaps

Before you start the paint, I would always suggest you fix the holes and openings -if any- on the wall. Although the soundproof paint is thick and will cover these holes, sealing them is a better option to reduce sound significantly. For that, you can use green glue, which is a capable soundproof sealant with good reviews. Simply read the instructions on the packaging and use it to fix all the holes and gaps for even better results.

Soundproof Paint Application Tips

Applying soundproof paint is a bit different from applying regular paint. It does require a brush and the usual equipment, but you need to consider a few essential things to ensure proper and beneficial results:

  1. Before you get started, make sure you have enough paint to cover the whole area. Because soundproof paint is much thicker than the ordinary paint, it would give much less coverage. It has been estimated that 1 gallon of soundproof paint usually covers 100 square-feet of the wall with a single coat. So make sure you buy enough to cover your wall adequately.
  2. Because of its thickness, it takes a lot more time to dry out than the regular paints. So you have to wait for 16-32 hours before applying the second coat. The process takes even longer if the temperature is low. In this case, you can heat the room to speed up the drying process.
  3. The thicker the layers of paint, the better the result. I would suggest applying at least three or four coats for good results.
  4. The soundproof paint is usually not very smooth due to its composition. But, you can use regular paint over the soundproof paint once it has dried out, for a smooth texture on the wall.
  5. Make sure you fully cover the entire wall and do not leave any gaps in it. You can use a roller or a pressure sprayer for excellent coverage on the walls. I would suggest you use a pressure sprayer for this purpose because it sprays the paint all over the wall evenly and doesn’t spill paint on the floor. Also, you can paint those areas that are out of reach with the sprayer. In case it drops on the floor, just use a mixture of soap and water to clean off the surface.  Ensure you cover the electrical switches before you start this process.
  6. Just remember that you do not have to paint your entire house for good results. Just pinpoint the noisy spots and only cover them with the soundproof paint and the rest with the regular paint.
  7. For the best results, you can combine soundproof paint with any other soundproofing techniques mentioned above.
  8. Just don’t go around painting your walls with several layers of ordinary paint to soundproof it. It doesn’t work that way. Once dried, the regular paint reduces its thickness to a few centimeters, no matter how many coats you have applied. So, instead of wasting your time and money, do some research and choose an excellent soundproof paint.
