Usage

• Surfaces to be bonded must be free of dust, grease, and oil.
• For bonding large, homogeneous surfaces or in very dry conditions, lightly spray surfaces with water (approx. 5–10 g/m²).
• It is recommended to clean surfaces with Kiilto Cleaner 303 and prime with Kiiltoflex Metalliprimer.
• Cut the cone end of the cartridge. Screw the nozzle onto the joint and cut it to the desired size corresponding to the joint width.
• Apply the adhesive with a manual or compressed air gun. If necessary, smooth to the desired shape with a moistened spatula.
• After use, carefully seal the packaging.
• Uncured product can be cleaned with white spirit or acetone. Cured product can only be removed mechanically.
• Ambient conditions (humidity, temperature), material moisture, and adhesive quantity significantly affect skin formation and curing time.
