Acoustic Sealant – Intumescent – Residential & Commercial Use

Product Overview

This high-performance acoustic sealant & adhesive comes in a 900ml cartridge, offering a durable, flexible solution for professional sealing and bonding applications. It is designed for use in dry lining, plasterboard installation, and insulation systems, providing an effective acoustic barrier that minimizes sound transmission through joints, gaps, and voids. This formulation offers strong initial grab with excellent adhesion to plasterboard, timber, metal studding, and blockwork. Once cured, it remains flexible to accommodate low to medium movement without cracking or loss of adhesion. The sealant’s white finish allows for direct overpainting once fully cured, ensuring a clean, professional appearance.

Features & Benefits

• High strength and flexibility: Forms a durable, permanently elastic joint resistant to cracking or movement.
• Dual performance: Functions effectively as both a sealant and adhesive, simplifying on-site installation.
• Excellent adhesion: Bonds securely to plasterboard, wood, metal studding, and masonry without primer on most substrates.
• Acoustic performance: Provides a reliable sound barrier for walls, floors, and ceilings in partition systems.
• Mould resistant: Resists biological growth in humid or internal environments.
• Non-flammable: Safe for use in a wide range of construction and finishing applications.
• Overpaintable surface: Accepts most conventional paints after full cure for seamless finishing.
• Easy cleanup: Can be cleaned from tools and surfaces with water before curing.
• Size 900ml: Supplied in a large-volume cartridge suitable for high-coverage professional use.

Applications

• Drylining and partitioning: Seals perimeter and abutment gaps in plasterboard systems to enhance acoustic insulation.
• Board bonding: Fixes plasterboard to blockwork, studding, and other common substrates.
• Insulation installation: Bonds kraft-lined and other insulation boards where acoustic and adhesive performance are required.
• Ceiling and floor joints: Seals junctions between boards and other building elements to reduce sound transfer.
• General interior sealing: Suitable for most internal gaps where flexibility and adhesion are needed.

Installation Guidance

• Surface preparation: Ensure all surfaces are clean, dry, and free from dust, oil, or loose coatings. Prime new plaster or porous surfaces with diluted PVA Bond (1:4 with water).
• Application method: Apply using a standard cartridge gun and tool down as necessary.
