It can be used as a primer, mid-coat, finish coat or as a single-coat system in atmospheric and immersed environments. Jotamastic 87 is primarily designed for maintenance and repair. In the marine industry, it can be used on outside hulls, exterior and interior areas including water ballast tanks and it can be used as a protective coating for offshore environments like splash zones, refineries, power plants, bridges, buildings, mining equipment and general structural steel.
