Jotamastic 80 by Jotun is a high-solids, surface-tolerant epoxy mastic primer engineered specifically for maintenance and repair in atmospheric environments. Designed for situations where optimal surface preparation isn't possible, Jotamastic 80 ensures strong adhesion, reliable protection, and extended coating life — even on aged coating surfaces and sub-zero temperature applications.
Suitable for carbon steel and previously coated substrates, Jotamastic 80 functions effectively as a primer, midcoat, or a single-coat system, making it highly versatile and user-friendly. For immersed environments, Jotamastic 80 Aluminium is the recommended alternative for superior underwater durability.
Whether for industrial structures, offshore platforms, or steel infrastructure, Jotamastic 80 provides trusted corrosion protection and application flexibility, reducing downtime while extending maintenance cycles.
