Acoustic Sealant

The Acoustic Sealant is a high-strength, flexible adhesive and sealant designed to enhance the acoustic integrity of any space. By filling gaps, sealing edges, and preventing sound leakage, this sealant is an essential component for soundproofing projects. Formulated to be non-flammable, solvent-free, and paintable once cured, it ensures durability and performance for walls, ceilings, and dry lining applications.

What is Acoustic Sealant?

Acoustic Sealant is a specialised mastic designed to block sound transmission by sealing gaps, cracks, and perimeters where sound might escape. It is engineered to remain permanently flexible, ensuring it adapts to natural building movements while maintaining its acoustic properties. In addition to soundproofing, many acoustic sealants are fire-resistant, offering added protection in construction projects.

Key Characteristics:

• Flexibility: Permanently flexible for natural movement.
• Adhesion: Bonds to a wide range of building materials.
• Paintable: Can be painted once cured for a seamless finish.
• Non-flammable: Provides safety in high-risk areas.
• Solvent-Free: Easy and pleasant to work with.

How Does Acoustic Sealant Work?

Acoustic sealant works by creating an airtight barrier that prevents sound waves from escaping through small gaps, cracks, or seams in building structures. Here's how it achieves its soundproofing effect:

1. Filling Gaps and Cracks:
• Sound can travel through even the smallest gaps, reducing the effectiveness of soundproofing materials. The sealant fills these gaps to block sound transmission.
2. Dampening Vibrations:
• By sealing perimeters and edges, it reduces flanking vibrations that can transfer sound energy across structures.
3. Maintaining Acoustic Integrity:
• Its flexibility ensures that the sealant adapts to the natural movement of the building, keeping the structure airtight over time.

How Effective is Acoustic Sealant at Stopping Nuisance Noise?

Acoustic sealant is highly effective when used correctly:

• Sound Reduction:
• It can prevent soundproofing performance losses of up to 10% by sealing gaps and edges.
• Flanking Noise Control:
• Reduces vibration and secondary noise pathways.
• Durability:
• Remains effective over its lifetime due to its flexible and strong formulation.

While acoustic sealant alone cannot block all sound, it significantly enhances the performance of other soundproofing materials by sealing weak points.

Where Can Acoustic Sealant Be Used?

The versatility of acoustic sealant makes it suitable for a wide range of applications:

• Perimeters and Edges:
• Seal the edges of floating floors, walls, and ceilings to maintain acoustic performance.
• Service Openings:
• Fill gaps around pipes, cables, and other service penetrations.
• Cracks and Gaps:
• Fill gaps in timber floorboards, between floor decking, or along seams in plasterboard.
• Insulation Boards:
• Bond and seal acoustic insulation boards for a complete soundproofing solution.

How to Use Acoustic Sealant?

Using acoustic sealant is straightforward. Follow these steps for optimal performance:

1. Preparation:
• Ensure the surfaces are clean, dry, and free from dust or grease.
• Remove any loose material or debris from gaps and edges.
2. Application:
• Use a caulking gun to apply the sealant directly into gaps, cracks, or along perimeters.
• For best results, apply in a continuous bead and smooth with a tool or finger for a neat finish.
3. Setting Time:
• The sealant typically cures within 2-3 hours and can be worked with for up to 90 minutes.
4. Finishing:
• Once cured, the sealant can be painted over for a seamless look.

What are the Benefits of Using Acoustic Sealant?

1. Enhanced Soundproofing:
• Prevents sound leakage and flanking noise, improving the performance of soundproofing materials.
2. Fire Resistance:
• Many acoustic sealants offer fire-resistant properties for added safety.
3. Flexibility:
• Adapts to building movements without cracking or losing effectiveness.
4. Durability:
• Maintains performance over time, even in demanding environments.
5. Ease of Use:
• Easy to apply and clean, suitable for professional and DIY applications.
6. Compatibility:
• Bonds well with a wide range of materials, including plasterboard, insulation boards, and timber.
7. Eco-Friendly:
• Solvent-free and non-flammable, making it safe and pleasant to work with.

The Acoustic Sealant is an indispensable tool for anyone seeking to create a quieter, more comfortable space. Its ability to block sound leakage, dampen vibrations, and maintain acoustic integrity makes it a must-have for soundproofing projects. Whether you're working on a home renovation, office upgrade, or industrial soundproofing, acoustic sealant ensures professional and long-lasting results.
