2. Cut the cartridge tip without damaging the threaded section.
3. Fit the nozzle and cut it to the required bead size.
4. Apply using a standard sealant gun.
5. Use small beads or a zig-zag pattern for bonding and a continuous bead for sealing.
6. Press bonded parts together firmly and tool sealant before skin formation.

Apply neatly because the completed joint will remain visible. Heavy, overhead or safety-critical components should be temporarily or mechanically supported until the adhesive has cured.

Important limitations

Consult the latest Sika Product Data Sheet before use. Test compatibility with plastics, coatings and natural stone. Do not use for structural glazing, aquarium manufacture, contact with bitumen or asphalt, or substrates that bleed oil or plasticiser. Wet-surface adhesion does not make the product suitable for permanent water immersion.
