International Yacht Paint Interlfill 830, Curing Agent (B) Grey, 2.5Lt

The International Interfill 830 Curing Agent (B) is an essential component of the Interfill 830 epoxy filling and fairing system and must be combined with the corresponding Base (A) before application.

Once mixed correctly, Interfill 830 forms a low-density epoxy filler with excellent strength, impact resistance and water resistance. It is especially suitable for steel, aluminium and composite hulls, including larger areas that require accurate fairing and profiling.

The mixed system can be applied up to 20 mm thick in a single coat at 23°C without sagging, making it ideal for correcting uneven surfaces, filling depressions and achieving a smooth hull profile before painting.

After curing, Interfill 830 is easy to sand and can be overcoated with compatible International epoxy primers such as Interprime 820, Interprotect or Interprime 880.
