01
Start with an area-by-area specification先把各部位的使用环境分清
An underwater hull, a weather deck and a ballast tank do not face the same exposure. Separate immersed antifouling from atmospheric finishes, and define corrosion protection, wear resistance and cargo contact for each space. Shop primer and block-stage coatings also need to fit the later coating sequence.水下船体、露天甲板和压载舱面对的环境不同。水下防污体系与水线上部面漆应分别选择；各舱室还要考虑防腐、磨损和装载介质。车间底漆、分段涂装与后续涂层之间，也要提前安排好衔接。
02
Build preparation into the yard schedule把表面处理纳入船厂排期
Welds, edges, cut-outs and difficult-to-reach stiffeners deserve attention before coating begins. Agree the surface preparation, stripe-coating sequence and inspection points with the yard. Work completed at block stage must allow for erection damage, welding and the repair of transport marks.焊缝、边缘、开孔和不易施工的加强筋，应在涂装前处理。与船厂明确表面处理要求、预涂顺序和检查节点。分段阶段完成的涂层，还要为合拢焊接、运输损伤和后续修补留出安排。
03
Keep the specified system together按完整配套管理施工
Coat thickness, overcoating intervals and curing conditions belong to the selected system—not just the product name. For spaces subject to statutory or class requirements, check that the specified product, system and application procedure fall within the applicable approval. Retain batch details and coating records for future maintenance.膜厚、复涂间隔和固化条件需要对应具体配套，不能只看产品名称。涉及法规或船级要求的部位，应核对产品、配套和施工程序是否处于适用的认可范围内。保留批次与涂装记录，便于后续维修。
