屋顶防水层是指在屋面下层上，抹压或涂布具有屋顶防水能力的流态或流半态物质，经过溶剂、水分蒸发固化或交链化学反应，形成具有相称厚度并有肯定弹性的无接缝的完备薄膜，从而达到屋顶防水目的一种屋顶防水屋面情势。
Bao Steel waterproof layer refers to the roof, or coated with a waterproof wiping pressure flow ability or bucket fluid material, solvent, water evaporation after curing or chain chemical reaction, forming a complete film without joints with considerable thickness and has certain elasticity, so as to achieve a form of waterproof waterproof roof.
涂屋面屋顶防水层前（成都人事考试），对下层必须认真检查和需要的处理，要求下层外观平整、光洁、干燥（上海装潢），不得有酥松、起砂起皮等征象。假如找平层平整度超过规定要求，则应将突出部位铲平，低凹处用掺有乳液的水泥砂浆修补填平或用聚合物水泥浆涂刷；起砂、起皮处应将外观消灭，用聚合物水泥浆涂刷并抹压光。
Coated steel structure roofing waterproof layer, the base must be carefully checked and necessary treatment, neat, smooth surface, dry grass, there shall be no loose sand, peeling and other phenomena. If the leveling layer roughness exceeds the specified requirements shall be leveled the concave convex parts, mixed with cement mortar with polymer emulsion repair or fill slurry brushing; sand, skin at the surface shall be removed with polymer cement slurry brushing and wiping pressure light.
对基层验收合格后，涂刷与所用涂料材性相容的下层处理剂一道，以加强薇妮涂料与下层的粘接。
