Fire and Acoustic Gap Sealant - White (310ml)

Fire and Gap Acoustic Sealant

Colour: White

Size: 310ml

Fire & Acoustic Sealant is a single-component, gun-grade joint sealant designed to stop fires. Its acrylic-based formula provides a secure, yet adaptable seal to joints in a wide range of fire-rated structures. The sealant does not support combustion and will char and slightly intumesce when exposed to heat, halting the spread of smoke and fire through the joint.

Siderise Fire & Acoustic Sealant has been formulated to give improved sealing and application performance coupled with excellent fire-stopping properties.

Benefits:

• 3rd Party Product Certification
• Fire-rated in both horizontal & vertical joints
• No priming is required for most construction substrates and remains flexible for joint movement
• For use in small joints with excellent slump resistance
• 18 months shelf life
• Fast cure tack-free within an hour, easy to apply and tool off
• Halogen-free, resists fungi and vermin
• Excellent adhesion to most common building substrates Reduces sound transmission in joints
• No known effects on plastic pipes, cables/bunches, sheathing, or metallic components

Product Description

Fire & Acoustic Sealant is primarily intended for use with Siderise Firestop & Cavity Barrier Systems to ensure small gaps and imperfections are treated where it is otherwise not possible. This includes applications such as:

• Sealing around façade support brackets or penetrations
• Sealing joints to Firestops/Cavity Barriers where it is not possible to apply foil tape, such as imperfections in the slab edge creating gaps.

Fire & Acoustic Sealant is designed for sealing joints, voids, irregular holes in fire walls, floors, partitions and other structures and for maintaining their integrity when sealing around pipes and cables which penetrate them. It is also ideally suited for internal perimeter pointing of fire rated door and window frames.

Application instructions

All surfaces must be clean and sound, free from dirt, grease. The surfaces may be damp but not running wet. Use mechanical abrasion to clean porous surfaces before application to remove loose material. Particular attention should be paid to BS 6093 (2013) - codes of practice for the design of joints and jointing in building construction, when preparing a specification for a particular joint. In order to obtain maximum performance as a sealant, the width of the joint should be twice the depth, and the use of backing material is strongly recommended e.g. stonewool. Prepare joint by cleaning and priming if necessary. Cut nozzle to the desired angle and gun firmly into the joint to give a good solid fill. Strike off the sealant flush with the joint sides within five minutes of application, before surface skinning occurs. A small amount of shrinkage will occur on curing. If a flush finish is required, fill the joint slightly proud of the surface to allow for shrinkage.

Fire Performance

Fire & Acoustic Sealant has been tested in conjunction with backing materials in accordance with EN 1366-4:2006.
