［Objective/Significance］ Superhydrophobic coatings have significant potential in applications such as self-cleaning，anti-icing，and corrosion protection. The spraying method hasbecome an important approach for the engineering application of superhydrophobic surfaces due to itssimple process and ease of scalability. However，the micro-nano rough structure essential for superhydrophobicity in spray-coated surfaces is prone to failure due to filler shedding or wear，making poor durability a core bottleneck restricting their widespread application.［Analysis/Discussion/Progress］ This paper systematically reviews the research progress on the durability of spray-applied superhydrophobic coatings. Starting from the theory of wettability，it elucidates the inherent mechanism of hydrophobic failure and summarizes enhancement strategies from three aspects：micro-nano structure optimization（such as multi-level rough structure，self-similar morphology），filler-resin interface strengthening（such as chemical bridging，interface modifiers），and dynamic coating repair （such as reversible coordination bonds，hydrogen bonds）.［Conclusion/Prospect］Currently，althoughcertain progress has been made in the research and modification of spray-coated superhydrophobiccoatings，industrial application is still constrained by such as harsh service environments， environmental regulations，and cost. In the future，by continuously focusing on the long-term weather resistance，multi-functional synergistic enhancement，and green large-scale preparation technology of superhydrophobic coatings，we can gradually promote their industrial application.
