questions David Smith on 19/12/2018

Hi, Once the steel is painted with your fire resistant paint, can you paint over it with normal paint ie dulux or crown paints. Regards


No, only an approved Jotun topcoat should be used. Approved topcoats for Jotun Steelmaster 60WB currently include Jotun Conseal Touch-UpJotun Pioner TopcoatJotun Hardtop AXJotun Hardtop XPLJotun Hardtop HB and Jotun Futura Classic. You must check with our Technical Department before proceeding as Jotun do continually update their recommendations/approved topcoats.

  • For application details and overcoating, refer to the Technical Data Sheets (TDS) and Application Guides (AG) for the approved topcoats, as well as with SteelMaster Application Guide

  • The maximum total dft of the topcoat(s) should not exceed 125 microns.

  • 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.

  • SteelMaster surface must be clean, dry and free from contamination before applying the top coat

  • Only approved Jotun topcoats may be used on SteelMaster. Jotun does not accept responsibility for topcoats manufactured by third parties. Jotun does not have control over consistency or quality of products manufactured by other parties.

questions frank on 07/10/2016
Question: How many years protection will it give in a indoor enviroment

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.

questions richard cartlidge on 09/07/2016
Question: is it best to erect the steelwork (primed) then spray the fireproof paint after.?

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.

questions Simon glover on 14/10/2015

Will Jotun Steelmaster 60WB be ok to use on ducting for fire protection?


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.
