For maximum adhesion, remove all dirt, dust and rust and ensure that the area of application is clean.

Cut off the cartridge seal and screw nozzle onto cartridge. Cut the nozzle to the required bead size. Apply the adhesive from the cartridge, forcing it onto the area to be sealed, then immediately tool it down to ensure good adhesion. Complete tooling within 5-10 minutes.

When bonding materials, apply a bead of adhesive to one surface and immediately combine the two parts, applying pressure to ensure good surface contact.

Application equipment should be cleaned with warm water after use.

It is necessary to fully dry the product before subjecting to temperatures above 100°C to prevent gassing and likely failure or the seal/bond. Allow to air dry for 36-48 hours, after which gentle heat can be applied.

The dried product can be removed with boiling water.
