Best Acoustic Sealant – Buyer’s Guide
Are you looking to soundproof your home or office? If so, you’ll need to find the best acoustic sealant for the job. There are a lot of different products on the market, so it can be tough to decide which one is right for you. In this post, we’ll discuss the different types of acoustic sealants and recommend our top picks. Keep reading to learn more!
Acoustic Sealant vs Regular Caulk
First, you’ll need to know the difference between regular caulk and acoustic sealant. While they are both used to make spaces airtight, soundproofing is their primary purpose. Acoustic sealant is specifically designed for this job. It’s typically thicker than caulking and features a rubber-like consistency that allows it to fill larger gaps.
Caulk is a thin, gooey liquid made from latex or silicone. This sealant is used for smaller cracks and holes where sound could potentially get through. It’s best used on seams in walls and ceilings to keep out noise from the room below. Often, this type of caulk can be painted after it dries to match the surrounding decor.
Acoustic sealant is a little different. It can be used on seams, but it’s made to fit large gaps in place of weather stripping or other materials. This kind of sealant will not dry out if exposed to air and needs to be applied with a caulking gun for best results.
Tips & Tricks: How to Use Your Acoustic Sealant Correctly
The acoustic sealant comes in tubes similar to caulking. It’s most effective when applied with a caulking gun found at your local hardware store or online . You’ll want to make sure all seams are clean and dry before applying the sealant, lest you trap moisture behind the walls.
- Start by placing the tube of acoustic sealant into your caulking gun. Cut off the tip of the tube and place it over the notch on your gun where you’d load a standard cartridge of caulk.
- You should tape off the area around each seam before applying the sealant. This is necessary for two reasons. First, it prevents your walls from being stained by any excess sealant, which can be tough to remove. Second, it ensures that your seams are airtight once the sealant sets.
- You’ll likely need more than one tube of acoustical sealant for larger jobs. It’s best to work on one section at a time since acoustic sealant needs several hours to fully dry. If you apply too much at once, it will likely slide down your walls and form a large mess.
- Before you apply the sealant, place some on the tip of your finger. Rub it between your thumb and pointer finger to smooth it into an even consistency before applying it to the seams. Use long, upward strokes with the caulk gun to create a clean seal. Work in small sections at a time, clearing out your gun often to avoid clogs.

Best Acoustic Sealant: FAQs
What is acoustic caulking?
The acoustical caulking is used to seal all gaps on the perimeter of sound control walls, floors and ceilings. It can also be applied around electrical outlets or pipe penetration; once dry it becomes paintable in color choice which will match your other interior painting needs!
Does acoustic sealant work?
Acoustic caulk is a fantastic way to reduce external sound and increase insulation in your home by up-to 15%. Just apply it around edges, fill gaps & holes with this easy technique that has been proven successful time after again!
How long does acoustic sealant take to dry?
Acoustical sealant takes 48 hours to dry, so make sure you leave it alone for that long. Don’t interfere with the application process and also avoid applying any covering material until then!
Can I paint acoustic sealant?
As you should apply the sealant around light switches, windows, sockets, and to seal the gaps between bits of plasterboard, it’s good to know that acoustic sealant handles paint well. When you’re painting a room, this will ensure you can paint everywhere and still get a nice even finish.
How can I clean acoustical sealant?
To remove excess sealant and smears from the joint interface, use xylene or mineral spirits on a cloth. You can also clean any tools that come into contact with these materials by wiping them down using an appropriate cleaner like those found in your garage!

Major Things to Consider While Buying the Best Acoustic Sealant
Now that you understand the basics of buying acoustic sealant, it’s time to shop around for your perfect product! Here are a few key attributes you’ll want to consider when choosing the best product for your needs:
| 1. Water-Based or Solvent-Based Acoustic Sealant | Water-based acoustic sealants are a popular choice for their ease of use and low price. They’re also very safe to apply indoors, which is great if you suffer from allergies or sensitivity to chemicals. Water-based sealants don’t emit any dangerous fumes during application, so you can work on your soundproofing project worry-free. On the other side of the coin, solvent-based acoustic sealants are known to be more durable. Their thicker consistency helps them fill gaps better than water-based options. They’re also great for filling seams in concrete or brick, unlike water-based sealants that can’t bond to hard surfaces. This type may smell a bit more, but it’s worth the tradeoff for improved durability. |
| 2. STC Rating | The STC rating, or Sound Transmission Class, measures how well a material can block sound from passing through it. While the higher the STC number is, the better your acoustic sealant will serve its purpose. For example, a single-pane window that features an STC of 50 decibels blocks most outside noise from entering a room. |
| 3. Critical Listening Tests | Besides the STC, another way to see how powerful your acoustic sealant will be is by doing an A/B listening test. Get two people in the room with you and have each stand on either side of a wall or door that features your new sealant. If one person can hear the other clearly through the wall, then your acoustic sealant needs to be improved upon. If they can’t hear each other at all or there’s an obvious difference in volume levels, then you’re good to go. |
| 4. Waterproofing Ability | If you live in an area where it rains constantly, you’ll want to make sure your acoustic sealant is waterproof. Otherwise, any moisture that seeps through your walls will create a breeding ground for mold and mildew. Not only would this be bad for your health, but it can also damage the integrity of your structure and ruin your soundproofing. To put it bluntly, acoustic sealants that are waterproof are also more expensive because they’re designed to withstand harsh conditions. If you don’t live in an especially wet environment, then opt for a cheaper water-based product instead of splurging on the pricier waterproof option. |
| 5. Finishing Product | Another factor to keep in mind when shopping for the best acoustic sealant is what type of finishing product you’ll use on top. Acoustic sealants are available in either paint or caulk form. Paint gives a more even coverage and can be painted over if needed, but it may flake off with time. Acoustic caulk is thicker and may look less aesthetically pleasing, but it can bond to just about any surface. Also, it’s not as susceptible to peeling as paint could be. Whichever you choose is up to personal preference and the application process. Some people find that one product works better than the other depending on the situation, so consider this when making your decision. |

| Application Considerations | It is recommended a 1/8 to 1/4” (0.3 to 0.6 cm) gap be left around the perimeter of your wall or ceiling drywall to fill with Noiseproofing Sealant. Sealing gaps of 5/8” or more with the Sealant is not recommended, as it will not cure properly in large gaps. Instead, for excessively large gaps deeper than an inch consider using backer rod to fill the gap before applying Sealant. The sealant is only intended to be an acoustical seal; it is not intended to be a water seal or to be used in exterior applications. Do not use the sealant to seal around pipes or plumbing. |
