Everbuild Fire Mate is ideal for:
- 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.
APPLICATION
The surfaces to be must be clean, dry and free from dust, grease and other contaminants. Improve adhesion by wiping surface with a glass cleaner allowing all solvent to evaporate before applying sealant. Priming is generally not required, although we always advise testing small areas prior to use. Large voids should first be filled with EVERBUILD FIREFOAM B1 to maximize fire rating.
Cut the tip of the cartridge taking care not to damage the thread. Apply nozzle and cut at an angle of 45° with an opening slightly larger than the gap to be sealed. Apply using a standard sealant gun. Best results will be obtained by keeping an even pressure on the trigger and keeping the gun at a constant angle to the surface being sealed. To ensure a proper bond, always smooth the sealant down with a spatula or piece of wood wetted with linseed oil or white spirits. An improved joint appearance can be achieved by placing masking tape to both sides of the joint, removing within 5 minutes of application.
Single seal joints should be on the fire rated side of the structure.
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.
- Known to have compatibility problems with some cPVC pipping
