Everbuild Fire Mate Sealant

Everbuild Fire Mate Silicone Sealant

Quantity: 1 x C3 cartridge.
Colours Available: White, Brown, Grey.

Everbuid fire mate sealant is a five hour rated, one part, emulsion acrylic based, intumescent Acoustic sealant that gives a firm yet flexible seal to joints in a variety of fire rated structures. Tested following the principles of BS EN 1366-4:2006 as detailed in Warrington Fire Research Report No. 181967 (May 2009).  Acoustic rated to BS EN ISO 140/3. Tested for air permeability to EN13141-1. The product, in suitably designed joints will resist the passage of fire for up to 5 hours. The selected fillers used in this formulation also make it suitable for use as an acoustic sealant.

Benefits
• When exposed to heat, it swells greater than 3 x its original   size, so creating a char that will resist  the passage of  fire for up to 5  hours.
• No priming required for most construction substrates
• Flexibility factor 12.5%
• For use in joints up to 50mm wide.
• Excellent acoustic properties for sound deadening - Average noise reduction of 35.9db (100-3150Hz)
• Non slump - easy to apply and tool off.
• Fast cure - tack free in 15 minutes.
• Over paintable.

Areas For Use
• Sealing joints, voids and irregular holes in fire walls, partitions and other structures; also for maintaining  the integrity  of pipes and cables that penetrate them.
• For internal perimeter pointing of fire rated door and window frames.

Limitations
• Not for use on substrates that may bleed oils, solvents or plasticisers.
• Not for use where joints are constantly immersed in water, or as part of structural glazing systems.
        
Surface Preparation
All surfaces must be clean, dry and dust free.  All loose or flaking surface coatings, and old sealant and mastic joints, should be removed before application.

Tools/Products Required:

• Everbuild Fire Mate Sealant

• Caulking Gun.

• Silicone Smoother + Water.

• Backer Rod

Step 1 – Cleaning Surfaces: 
Surfaces need to be clean, dry, sound and free from contamination. NOTE: Soap or residue will stop the silicone from adhering.

Step 2 – Preparing Surfaces: 
Where gaps are 6mm or wider, insert a joint of closed cell Polyethylene foam backer rod, approximately 25% over sized, allowing for a seal depth of at least 10mm. If necessary you can mask around the perimeter allowing you to remove any messy silicone after application.

Step 3 – Preparing Caulking Gun: 
Insert the Firemate sealant cartridge into the skeleton gun. Snip the nozzle at a 45 degree angle using a sharp blade as any ragged edges will reflect in your silicone. Don’t snip the nozzle too large, this will make it very difficultly and messy when applying.

Step 4 – Applying Sealant: 
Pressure the gun trigger so that a smooth constant bead of silicone comes out, and adjust your speed of travel to ensure a uniform bead goes down. Remember not to put too much silicone down as it will spread as you smooth it.

Step 6 – Smoothing: 
Wet the silicone smoothers and tool to get the right shape, adjusting any mistakes made when applying the sealant. Now is the time to also remove any masking tape used.

Joint Width:
Where gaps are less than 6mm wide, apply a bead of sealant and tool to form a triangular fillet, achieving a ‘bite’ of at least 6mm onto non-porous surfaces ( PPC, aluminium etc) and 10mm onto porous surfaces (brickwork etc).
Minimum 6mm.
Maximum 25mm.

Joint Depth: 
Depth ratio (within the above min/max restrictions) 2:1 butt joints. 1:1 lap joints
