Product Information
Full details
The Everbuild AC50 Acoustic Sealant and Adhesive is a professional-grade solution designed for contractors and DIY enthusiasts who need to enhance sound insulation in stud partition walls, ceilings, and floors. Its primary benefit is providing a permanently flexible, high-performance seal that effectively reduces sound transmission through joints and gaps. Users should note that while it is an excellent acoustic barrier, it is primarily intended for indoor applications and requires a standard skeleton gun for application.

FAQs
Can I use Everbuild AC50 outdoors?
No, this product is designed for internal use only and is not formulated to withstand external weather conditions.
Is the AC50 paintable?

What tools do I need to apply this?
You will need a standard skeleton (caulking) gun to dispense the sealant from the cartridge.
Does it cure clear?
No, AC50 is supplied in a white finish and remains opaque after curing.
How long does it take to dry?
Skinning time is typically 10-15 minutes, but full cure time depends on the depth of the bead and environmental conditions, usually taking 24-48 hours.
Can I use it on metal studs?
Yes, it adheres well to metal stud work, making it ideal for soundproofing partition walls.
Troubleshooting
Sealant is difficult to extrude from the cartridge.
Ensure the cartridge tip is cut properly and the skeleton gun mechanism is not obstructed; in cold conditions, warm the cartridge slightly to room temperature.
Sealant is cracking after drying.
Ensure the joint width does not exceed the movement capability of the product; check that the substrate was free of moisture and contaminants before application.
Poor adhesion to surface.
Thoroughly clean the surface with a degreaser and ensure it is completely dry before re-applying the sealant.
