DownloadQuestions
![]() | Question: How many years protection will it give in a indoor enviroment |
Answer: 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. | |
![]() | Question: is it best to erect the steelwork (primed) then spray the fireproof paint after.? |
Answer: 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. | |
![]() | Question: Will Jotun Steelmaster 60WB be ok to use on ducting for fire protection? |
Answer: 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. | |
