Mildew and moisture resistance requirements of ultra-thin fireproof coating for steel structures in grain storage plants

粮库常年高湿、水汽大，谷物呼吸带来持续潮气，极易诱发涂层霉变、鼓包、附着力衰减，进而削弱防火能力。

Grain storage maintains high humidity year round. Moisture released by grain respiration easily causes mildew, blistering and adhesion loss, weakening fire protection performance.

选型优先选用添加防霉组分、通过湿热循环检测的产品，严格核验耐水、耐湿热、防霉等级；施工前做好基面防潮底漆，控制环境湿度再喷涂，完工预留通风养护周期，保障长效稳定。

Priority shall be given to products with mildew-resistant additives and qualified damp-heat cycle tests. Check water resistance, damp-heat performance and mildew grade strictly. Apply anti-corrosion primer before construction, control site humidity and reserve ventilation curing time for long-term stability.
