The FAQ's below are for general guidance only. For specific questions, please refer to the application guides and data sheets on our product pages or give us call and we will answer any questions that you have.
Q. What is the primary function of SteelMaster 600WF?
A. SteelMaster 600WF provides up to 60 minutes of fire protection for structural steel exposed to cellulosic fires, enhancing building safety.
Q. Is SteelMaster 600WF environmentally friendly?
A. Yes, it is a waterborne coating with low VOC content, aligning with sustainable building practices.
Q. Can SteelMaster 600WF be applied over any primer?
A. It should be applied over Jotun-approved primers to ensure compatibility and optimal performance.
Q. What application methods are suitable for SteelMaster 600WF?
A. It can be applied using airless spray, brush, or roller, with airless spray being the most efficient method.
Q. How should the surface be prepared before application?
A. Surfaces must be clean, dry, and free from contaminants, with an appropriate primer applied beforehand.
Q. What is the recommended storage condition for SteelMaster 600WF?
A. Store in a dry, cool, well-ventilated area away from heat sources, with containers tightly closed.
Q. Can SteelMaster 600WF be used in exterior environments?
A. It is primarily designed for interior use. If used outdoors, it must be immediately top-coated with a weather-resistant product such as Hardtop XP.
Q. What is the shelf life of SteelMaster 600WF?
A. When stored properly, it has a shelf life of up to 6 months at 23°C.
Q. Is thinning required before application?
A. Thinning is not typically necessary; use as supplied after thorough stirring.
Q. How is the required dry film thickness (DFT) determined?
A. DFT is specified based on the desired fire protection duration and structural requirements; refer to project specifications. Contact us and we will calculate the film thickness of paint necessary to meet your specification. There is no charge for this service.
Q. Can SteelMaster 600WF be top-coated for aesthetic purposes?
A. Yes, it can be overcoated with compatible topcoats such as Conseal Touch-Up for colour and additional protection.
Q. What environmental conditions are ideal during application?
A. Apply when substrate and ambient temperatures are between 10°C and 35°C, with relative humidity below 85%.
Q. How long does it take for SteelMaster 600WF to fully cure?
A. Full curing typically occurs within 7 days at 23°C. However, curing times may vary depending on temperature, humidity, and ventilation. Lower temperatures can extend the curing process.
Q. What is the minimum dry film thickness (DFT) required for 60-minute fire protection?
A. The required DFT depends on the steel section size and fire rating requirements. The specific thickness should be determined based on project specifications and fire test certifications.
Q. Can SteelMaster 600WF be applied to galvanized steel?
A. Yes, but the galvanized surface must be properly prepared by degreasing and lightly abrading to ensure good adhesion. A suitable primer, such as Jotun Barrier or Jotacote Universal, should be applied before SteelMaster 600WF.
Q. Does SteelMaster 600WF have an expiry date?
A. Yes, when stored correctly in sealed containers at temperatures between 5°C and 35°C, SteelMaster 600WF has a shelf life of approximately 6 months from the manufacturing date.
Q. How should application tools be cleaned after using SteelMaster 600WF?
A. Since it is a waterborne product, tools and equipment should be cleaned immediately after use with warm water and detergent. Dried paint may require mechanical removal.
Q. What are the advantages of SteelMaster 600WF over solvent-based intumescent coatings?
A. SteelMaster 600WF offers lower VOC emissions, faster drying times, and easier cleanup with water, making it more environmentally friendly. It also allows for reduced film thickness, improving efficiency without compromising fire protection performance.
