* Users are responsible to carry out test prior to installation to confirm compatibility with actual substrates, work conditions, and service requirements.
- Surfaces must be structurally sound, clean, dry, free of dust, dirt, flaking paint, loose particles, grease, oil or water. For smooth surfaces, adhesion can be improved by lightly sanding bond areas.
- Cut tip off and puncture the internal foil seal with nozzle. Cut nozzle tip to a 6 mm diameter hole (or desired size) and apply to substrate with cartridge gun.
- Apply adhesive bead along the length of object like batten, stud or joist. If object has a broad flat surface, apply beads in a zig-zag manner, or vertical lines (e.g. mirrors in bathroom) with a gap of 30mm – 70mm depending on object size and weight.
- It can be applied either as a “two-way contact” or a “one-way stick” adhesive.
4.1 “Two-way contact” (bonding of lighter objects): Apply adhesive to one surface. Press both surfaces together firmly to transfer the adhesive, and then pull both surfaces apart. Allow adhesive to tack off for 10 to 30 seconds and then reposition and press firmly together again. Use a rubber mallet to tap along the bonded area to ensure good adhesion.4.2 “One-way stick” (bonding of heavier objects): Apply adhesive to one surface. Press both surfaces together firmly and fasten them securely with clamps, nails, or screws. Maintain the fastening for a minimum of 24 hours.
- Uncured adhesive can be removed with a piece of cloth, with solvent / mineral spirits / Turpentine if necessary. Dried adhesive can only be removed by scraping or sanding.
A single 300ml cartridge can extrude a bead of adhesive approximately 10m long with a diameter of 6mm.
- Store properly in a dry and well-ventilated place with temperature below +30°C.
- Use within 18 months from date of production.
- Cartridge – 300 ml (24 cartridges / carton)
- Always test before use – user is responsible to test before using to confirm the product produces desirable results.
- If working in an area with poor ventilation or in a confined area, wearing a mask is recommended. Avoid contact with skin, eyes and avoid breathing in vapour. Contact doctor if swallowed.
- If skin contact occurs, wipe off excess and remove contaminated clothing, wash affected area thoroughly with soap and water. For further health and safety information, please refer to the latest Safety Data Sheet.
NOT recommended for the following applications:
- Mirror bonding
- Polystyrene / PU foam bonding
- Outdoor areas exposed to continuous weathering
- Areas with temperatures below 5°C or above 70°C
- Areas with permanent water immersion
- Areas or substrates that are constantly damp
- Overhead mirror installations
- Polyethylene, polypropylene, PTFE, silicone, bituminous substrates
