Wintergrade version of Jotamastic 90 for application below 10°C and faster curing times in normal conditions.


Jotamastic 90 offers the longest lifetime in any environment. It has exceptional corrosion resistance, is fast drying - greatly improving efficiency, and is designed to be safely applied from 100 to 300 microns in a single coat over a wide temperature and humidity range.


Jotamastic 90 is surface tolerant and can be applied on surfaces that appear dry but where moisture remains and flash rusting has begun. It is ideal for use when blast cleaning is not possible.


Due to the extensive colour range it can be colour matched with the topcoat improving coverage. It can also be used as finished coat in areas with low UV exposure or where colour retention is not the primary focus.


Note:  The pack size (including hardener) is 5 litres and 20 litres nominal as the exact quantity of paint is colour dependent (the quantity of tint varies with each colour).


Use the Standard version for application above 10°C and slower curing times giving a longer pot life.


Use the AL (Aluminium flake) Wintergrade version for increased coating flexibility, strength and an impenetrable barrier to water (only available in aluminium colour).


Recommended topcoats (above the waterline):

  • Standard: Pioner Topcoat
  • Premium: Hardtop AX
  • Eco: Hardtop CA
  • Other topcoat options available. Please call us for advice.
