• Prior to application of the topcoat ensure the SteelMaster system is fully dry to recoat and the SteelMaster system has been applied at the specified dft.

No by brush only. If spray application is required use the aerosol version instead.

Jotun Steelmaster 60WB itself does not offer any corrosion protection. However, when used with the correct primer/topcoat combination you can achieve up to 15 years expected service life from the system as outlined in ISO 12944-2.

For an internal C3 environment, a suitable primer and Steelmaster 60WB alone should give the required protection. If Steelmaster 60WB is to be left exposed and not clad or boarded in, a suitable topcoat should be used to finish the system to prolong the service life and achieve the 15 year + durability.

Yes it is. Ensure the building is at a stage where the steels are protected from the elements, dry and internal before applying Jotun Steelmaster 60WB

Jotun Pilot QD Primer is a compatible primer and often used under Steelmaster 60WB on bare, prepared mild steel sections. Jotun Pioner Topcoat is often used as a compatible finish if required.

No, Jotun Steelmaster 60WB is for structural steel members in a building. Duct work is normally thin galvanised metal sheet rolled up to form the ducting tubes and is too thin to protect with an intumescent paint of this kind.
