QUALICOAT Expands On Its Specifications

By Chris Mansfield, QUALICOAT Chair - The 25th edition of the QUALICOAT Specifications, approved in November 2024 and effective from January 1, 2025, introduces refined QUALIDECO criteria for decoration of coated aluminium used in architectural applications. This new appendix expands the specification to specifically address decorative finishes, including technologies like sublimation and powder-on-powder.

Furthermore, it sets out rigorous requirements for gloss levels, measured at a 60° angle, coating thickness, with a minimum of 80% of the specified 60 µm across multiple points, resistance to humid atmospheres containing sulphur dioxide, and other environmental durability tests. Additionally, the 2025 Specification includes clear procedures for licensing and quality control. Only QUALICOAT-approved plants and materials may be used, new technologies are constantly reviewed prior to approval, based on detailed testing by accredited laboratories.

The Specification also outlines the use of "self-tested decoration" lists, where suppliers must test each new Class 1 decorative finish in their own laboratories and maintain accessible records for QUALICOAT’s independent inspectors to verify during license renewals. Overall, the 2025 update strengthens consistency, traceability, and performance of decorative coatings used on architectural aluminium projects. The 2025 Specification also reflects QUALICOAT’s wider focus on sustainability and accountability in architectural finishes. With the growing use of recycled aluminium and decorative surface treatments, the new rules ensure that performance is not compromised by material choice or design trends.

By requiring tests such as sulphur dioxide exposure and accelerated weathering, the specification guarantees that coatings can endure aggressive urban or coastal environments while maintaining appearance and structural integrity. This is particularly important for projects where aesthetics and durability are equally critical, such as façades, curtain walling, and decorative elements. Another notable element is the tightened inspection and compliance regime. Independent inspectors will continue to conduct unannounced visits, but now with expanded powers to cross-check laboratory data against on-site production and supplier records.

This transparency helps prevent sub-standard finishes from entering the supply chain and reassures architects, specifiers, and clients that certified products truly meet the highest benchmarks. In short, the 2025 QUALICOAT Specification is not just an incremental update, it strengthens the system to support design freedom, long-term durability, and the Industry commitment to responsible, high-quality surface finishing. QUALICOAT is the world’s only global specification for architectural powder coating.

Since 1986 the Association has pioneered the development of powder coating technology through its membership and continue to improve specification documents that all of its members are obliged to follow. The Specification not only specifies the robustness of the finished coating, but also details process controls which are crucial to maintaining quality. By ensuring Members are third party assessed to demonstrate compliance with the Specification ensures consistent quality, a Member of the Association demonstrates this accreditation by proudly displaying their QUALICOAT logo and licence number.
