Unconditional steel protection

Engineered for the most challenging conditions

Demanding surfaces

Hydro jetting is frequently used but flash rust easily develops on the treated surface. This requires an epoxy primer that minimizes the risk of coating failures due to challenging surface preparation. Jotamastic can be applied on most clean and sound surfaces, even on early flash rusting and surfaces prepared by hydro jetting.

Harsh weather

Jotamastic is the ultimate choice of maintenance primer for enduring harsh weather conditions, due to its exceptional durability and protective qualities. Its unique technology provides a robust barrier against extreme temperatures and corrosive elements.

Challenging environments

Jotamastic is the optimal choice of maintenance primer for a variety of climates. The advanced technology provides a robust shield against the challenges posed by extreme weather conditions. Its ability to accommodate fluctuating temperatures and varying humidity levels sets it apart from other primers, ensuring long-lasting steel protection regardless of the climate.

Complex maintenance

Jotamastic secures flexible and efficient application solutions for small high-performance touch-ups, as well as bigger maintenance jobs. Robust and dependable, even with a wide range of application methods and in unpredictable conditions, it offers short overcoating intervals and fast curing time.
