Product Criteria
Design requirements
Specially designed as a reactive fire protection system for steel constructions. Designed to protect up to 150 minutes on a wide range of I section beams and columns. Fire tested and approved to BS 476 part 20/21. Suitable for structural steel exposed to internal environments. For a detailed coating specification please contact your local Zone/Jotun representative.
Installation requirements
The required quality of surface preparation can vary depending on the area of use, expected durability and if applicable, project specification. Metal surface preparation refers to requirements for preparation prior to application of approved primers.
This product must always be applied over a primer approved by Jotun. Only approved and qualified primers can be used in conjunction with this product.
Intumescent coatings require a greater degree of environmental monitoring than conventional coatings. They are moisture sensitive and must be protected against high humidity, rain and consequent water ponding both during application, transportation or during storage prior to being erected at site.
Where a topcoat is specified, application must occur as soon as the final coat of this product is fully through dry. During construction, exposed SteelMaster must be protected from weather with a topcoat. Refer to Application guidelines for more in depth documentation.
Maintenance requirements
The coating system shall be maintained by Owner who needs to ensure the coating systems are inspected at regular intervals not exceeding 18 months and an inspection report is made. Any damage or coating imperfections detailed in the report and not covered under the provisions of a Jotun Guarantee shall be repaired as quickly as reasonably practicable but in no event later than 6 months after the date of inspection. These repairs shall be carried out in accordance with Guarantor’s recommendations using Guarantor’s products. Guarantor shall upon request receive copies of Owner’s inspection reports.
Warrantees
Jotun provides a Product Performance Guarantee for specified systems when applied and maintained in accordance with the manufacturer guidelines.
