1.1本规程包括在涂覆涂料之前清洁混凝土表面，以清除油脂、污垢和松散材料。程序包括扫帚清洁、真空清洁、鼓风清洁、水清洁、洗涤剂水清洁和蒸汽清洁。 1.2本规程的目的不是改变混凝土的表面轮廓，而是清洁表面。 1.3本标准可能涉及危险材料、操作和设备。本标准并非旨在解决与其使用相关的所有安全问题。使用本标准的人有责任在使用前咨询并建立适当的安全和健康实践，并确定监管限制的适用性。有关具体预防措施，请参阅第5节。 ====意义和用途====== 表面清洁用于准备混凝土表面，以便涂覆用于照明的涂层- 值班服务。 当保护系统将用于连续或间歇浸入、机械负载或需要最佳结合以获得满意性能的保护系统时，不打算单独使用本规程（见规程D 4259和D 4260） ).

1.1 This practice includes surface cleaning of concrete to remove grease, dirt, and loose material prior to the application of coatings. Procedures include broom cleaning, vacuum cleaning, air blast cleaning, water cleaning, detergent water cleaning, and steam cleaning. 1.2 This practice is not intended to alter the surface profile of the concrete but to clean the surface. 1.3 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of whoever uses this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific precautions, see Section 5. ====== Significance And Use ====== Surface cleaning is used to prepare concrete surfaces for applying coatings intended for light-duty service. Use of this practice alone is not intended where protective systems will be used for continuous or intermittent immersion, mechanical loading, or for protective systems needing optimum bond for satisfactory performance (see Practices D 4259 and D 4260 ).
