Surface Preparation Requirements for Outdoor Fire Retardant Paint Application on Steel Structures
Primer System Application
After sandblasting, steel surfaces must be coated with a compatible anti-corrosion primer system. We specifically recommend the “Jinyu” brand epoxy zinc-rich primer combined with epoxy micaceous iron oxide intermediate coat to ensure proper adhesion with the outdoor fire retardant paint for steel.
Both primer and intermediate coats must form a continuous, defect-free film to completely seal the substrate, preventing potential delamination of the fireproof coating and steel corrosion.
Pengujian Kompatibilitas Primer Alternatif
When using other primer systems, comprehensive compatibility testing must be conducted either by certified laboratories or through on-site brush-out tests to verify proper bonding with the weather-resistant fireproof coating.
Pembatasan Aplikasi
Never apply the outdoor fire resistant paint directly onto:
Permukaan baja yang tidak dipoles
Lapisan galvanisDirect application may compromise coating performance and accelerate substrate corrosion.
Inspeksi Pra-Aplikasi
Prior to applying the hydrocarbon fire resistant coating, conduct thorough inspections for:
Cakupan primer yang lengkap
Kontaminan permukaan (debu, residu minyak)
✓ Structural integrity (cracks, weld defects)Proceed with the industrial fireproof coating application only after passing all quality checks.
