Product Testing & Information


Coat of Silence soundproof paint is applied using a 2-step application process of two layers of “resilient” base coat followed by a “mass building” finish coat. By increasing mass, Coat of Silence sound absorption paint reduces sound transmission through walls and ceilings. The Coat of Silence base coat layer retains resiliency over time and the durable finish coat is ready for the paint or wall covering of your choice.

Coat of Silence soundproof paint brings a 2-step system that can be sprayed onto any existing surface or with new construction. This sound absorption paint is a new proven soundproofing solution that keeps the noise out as well as the cost and labor down. Applications include hospitals, hotels, schools, condos, apartments, home media rooms, offices, retail centers, construction, and many more.

Step One

After priming your surface, two coats of Base Coat sound insulation spray is recommended for best sound reduction results.

  • Because of the sound dampening paint’s thickness, stir thoroughly with a drill or paddle.
  • Because a membrane is created, spray an ample coat without running.
  • To effectively achieve thickness of product, do a vertical and horizontal pass for each layer.
  • For best performance, wait 20-40 minutes between layers, or until product is dry.

Step Two

Two coats of this sound-absorbing paint’s Finish Coat are recommended for best performance.

It can be painted over by any kind of paint, including latex & enamel.

  • Because of product thickness, stir thoroughly with a drill or paddle.
  • Apply an even coat to ensure a consistent finished surface.
  • To effectively achieve thickness of product, do a vertical and horizontal pass for each layer.
  • For best performance, wait 20-40 minutes between layers, or until product is dry.

Application

An airless sprayer with a 317 tip and 1,800 to 2,400 psi is recommended. Be sure to clean the sprayer using soap and water within 30 minutes (after last use) or the material will begin to set inside the sprayer.

Please note: the dampening ability of the material is not affected by soundproofing paint application method.

Clean Up

Clean up can be done with soap and warm water.

Significant Sound Reduction

With the Coat of Silence 2-coat process, mid-range sounds become contained. Common noise is greatly reduced. We have reached an industry high – even the test labs were a buzz. To date, no other sound reduction solution can deliver with the consistency of Coat of Silence. Manufactured at the same high quality as major paint manufacturers.

Our patent-pending Coat of Silence resilient layer (Base Coat) is scientifically formulated to increase the STC rating of a room/partition by 3-7 points depending on the room construction and application methods. The Base Coat forms nano membranes that create sound absorbing and sound deflecting barriers. Our Finish Coat has the same sound deflecting formula to complete the sound reduction system.

No other sound reduction process offers such results with so little work. It’s tested in accordance with ASTM E90-09 and E413-04 as well as UL tested. Underwriter Laboratory has been testing products and helping to define standards for more than 75 years and they evaluate more than 19,000 types of products, components, materials and systems a year. With these testing standards, you know Coat of Silence silences the competition, as well as the room.

Coat of Silence Evaluation Graph

Coat of Silence Compared to Other Acoustical Treatments

Coat of Silence is often considered an alternative to installing acoustic panels or other sound-absorbing materials when seeking sound reduction solutions. While it may not provide the exact same level of performance as dedicated acoustic panels, it offers several advantages that make it an attractive option.

Easy Application

Coat of Silence is applied like paint, making it a user-friendly option that doesn’t require specialized skills or equipment. This ease of application allows for a more straightforward and convenient installation process compared to installing acoustic panels or other sound-absorbing materials, which may involve more complex mounting systems or professional assistance.

Versatility

Coat of Silence can be applied to various interior surfaces, including walls, ceilings, drywall, and plaster. This versatility allows for broader coverage and potential sound reduction across multiple areas of a room or space.

Effective Sound Reduction

While the exact capabilities of Coat of Silence may vary depending on factors such as the specific product used and application method, it is designed to provide effective sound reduction. It can help reduce sound buildup caused by hard and/or porous surfaces, which can contribute to noise transmission and reverberation within a space. Although it may not match the performance of dedicated acoustic panels, Coat of Silence can still make a noticeable difference in reducing sound levels and improving the acoustic environment.
