Application conditions

  • Application temperature (ambient and surface) between +5°C and +40°C.
  • On clean, uncontaminated, compatible, stable, grease-free and dust-free surfaces.
  • Ensure proper joint dimensions, for proper absorption of any movements.
  • Use a suitable brush to remove any loose particles from the surface.
  • Degrease the surface properly using Seal-it® 510 CLEANER.
  • Seal-it® 352 SUPER- PRO adheres excellently to many surfaces. We recommend priming highly porous (absorbent/open) surfaces with Seal-it® 520 PRIMER first.
  • For adhesive applications, apply material vertically (ventilation) in beads spaces between a minimum of 10 cm and a maximum of 20cm. Do not apply in dabs! It is recommended to use double-sided adhesive SEAL-IT® 560 PANELTAPE to support adhesion during the curing process and to achieve the correct adhesive thickness.
  • Use Seal-it® 550 FINISH to apply a smooth and tight finish, before skin formation.
