  • Do not apply if the ambient or substrate surface temperature is below +5 °C or above +40 °C. Optimal application temperature is between +5 °C and +25 °C.
  • At low temperatures, curing speed slows.
  • Not suitable for extremely aged or compromised walls.
  • The product may leave a stain on porous surfaces.
  • Wait a minimum of 28 days after painting to apply.
  • Mechanically fix valuable items.
  • For optimal performance, remove and re-apply glue every 2 years.
  • Selleys® recommends users conduct their own risk assessment before use to determine the product's suitability. A sample should be applied to the intended area to ensure acceptable appearance, finish, and performance on the substrate.

HOOKS

  • Apply the adhesive along the marked application lines on the back of the hook.

  • Use an amount of adhesive appropriate to the size of the hook.

  • Position the hook against the intended surface and apply firm, even pressure for approximately 30 seconds to ensure adequate contact.

  • Allow the adhesive to cure fully before applying any load.

  • Refer to the Load Capacity table for the relevant hook size

 

LIGHTWEIGHT MOUNTABLE MATERIALS

  • Apply the adhesive in dots approximately 10-15 mm in diameter, positioned about 30 mm from the edge of the material

    - 2 dots for approximately A4-size or smaller

    - 4 dots for approximately A3-size

    - 6 dots for approximately A2-size

  • Position the material on the desired surface and apply firm, even pressure for approximately 30 seconds to ensure good contact.

  • Allow the adhesive to fully cure before use.

    Undo

  • Grip or hold the edges of the hook or the attached item and firmly twist it anticlockwise to remove.

  • Never pull towards you, as this may damage the wall or surface.

  • Peel any residue from both the surface and the hook/item, then clean as necessary.

Notes:

As a guide, to facilitate clean removal, allow the adhesive to fully cure prior to removal. Under typical conditions, the product may remain adhered to porous substrates for up to 3 days and to non-porous substrates for up to 5 days before removal. For any remaining adhesive on textured surfaces, we recommend using Selleys Sealant Remover for easy clean-up.

 

Surface

  • Ensure all bonding surfaces are clean, structurally sound, and free from dust, oil, rust, or any other contaminants. The product is suitable for use on both dry and damp surfaces.

  • For non-porous substrates, clean the surface using a clean cloth lightly moistened with IPA or white spirit. Wipe in a single direction only, then immediately follow with a clean, dry cloth to remove any remaining residue.

Tube

  • Remove the cap and use the reverse end of the cap to carefully pierce the seal on the tube.

  • Squeeze the tube from the base to dispense the product.

  • Once the desired amount has been dispensed, replace the cap securely.

  • Retain the packaging for future reference and use.

Storage

  • Store unopened packaging below 25 °C in a cool, dry place away from direct sunlight.

  • Long-term exposure to elevated temperature can decrease material mechanical performance.

  • Unopened packaging is best used within 12 months from the date of manufacture.
