Jotamastic 80 is a two-pack epoxy mastic paint, which can be applied at low film thicknesses (from 75 to 200 microns in a single coat) . Jotamastic 80 is built on the same technology platform as Jotamastic 87 and is recommended as an anti-corrosive coating for steel above water.
The Aluminium Version is suitable for submerged areas. Aluminium flakes within the coatings create an impenetrable barrier to water and increased coating flexibility.
For best results apply two coats above the waterline at a typical spreading rate of 8 m² per litre.
Use the Wintergrade version for application below 10°C and faster curing times in normal conditions.
Recommended topcoats (above the waterline):
Standard: Pioner Topcoat
Premium: Hardtop AX
Eco: Hardtop CA
Other topcoat options available. Please call us for advice.
