Limitations
• Do not use on surfaces that bleed oils or plasticisers or in contact with bitumen or asphalt.
• Do not attempt to sand down. Finish smooth as per directions.
• Not overpaintable

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.

Application
The surfaces to be must be clean, dry and free from dust, grease and other contaminants.
Improve adhesion by wiping surface with EVERBUILD 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 for maximum fire rating.

Cut the tip of the cartridge taking care not to damage the thread. Apply nozzle and cut at an angle of 45o 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.
