Auralex STOPGAP_CASE StopGap Acoustical Sealant (Case)

High-Performance Acoustic Sealant
The Auralex STOPGAP_CASE StopGap Acoustical Sealant is designed to enhance the soundproofing of your space, ensuring that sound transmission is minimized. This highly elastic, water-based sealant is perfect for reducing sound leakage at the perimeter of wall systems or around electrical box cutouts. The surface dries to a tough film while remaining flexible and pliable for up to five times longer than alternative brands, making it an essential product for any soundproofing project.

Ideal for Various Applications
StopGap is perfect for a wide range of applications, whether you're working on a home studio, commercial space, or any area that requires sound control. Its flexibility and durability make it ideal for sealing gaps and cracks that can compromise the acoustic integrity of your room. Unlike other sealants, StopGap has no residual run-off, ensuring a clean and professional finish.

Easy to Use and Paintable
This sealant comes in a 29 oz tube and is paintable, drying white and non-staining to blend seamlessly with your existing decor. It meets ASTM E-84 standards for flame retardancy, providing both acoustic and safety benefits. The larger tube size requires a larger than normal caulking gun, which can be easily purchased at any local hardware store, making it convenient for any user.

Meets High Standards for Soundproofing
Auralex StopGap will achieve a Sound Transmission Class (STC) of 53 when applied in accordance with ASTM C-919 standards. To reach this STC rating, the sealant should be applied as two beads at the top, bottom, and all perimeter edges of the wall system. This ensures maximum effectiveness in reducing sound transmission, making your space quieter and more acoustically controlled.

Extensive Coverage
Each 29 oz cartridge covers approximately 32 linear feet with a 3/8 inch bead applied. This extensive coverage means that fewer cartridges are needed to complete your project, offering both cost efficiency and ease of use. The StopGap sealant remains flexible and pliable, providing long-term benefits and maintaining its effectiveness over time.
