Surface Preparation	High pressure fresh water wash or fresh water wash, as appropriate, and remove all oil or grease, soluble contaminants and other foreign matter in accordance with SSPC-SP1 solvent cleaning. All surfaces to be coated should be clean, dry and free from contamination.   Steel   Remove weld spatter and smooth weld seams and sharp edges. The surfaces should be blast cleaned to Sa2.5(GB/T 8923.1-2011).The weld seams areas could be cleaned to St3(GB/T 8923.1-2011)using power tool.   Apply 725-H44-85 before oxidation occurs. If oxidation has occurred, the entire oxidized area should be reblasted to the standard specified above.   Concrete   Remove loose powder of the cement, attached organisms, mud, oil or grease and other foreign matter thoroughly.   The surface can be abrade by blasting or using power tool to remove loose powder, attached organisms, mud etc. and oil can be cleaned by scour.   Repair/Maintenance   steel   The areas to be repaired should be cleaned to St3(GB/T 8923.1-2011)by  mechanical method or higher level of surface prepared to Sa2.5(GB/T 8923.1-2011)by abrasive blasting. Abrade the area immediately surrounding the repair to provide a key for subsequent coating application. Overlap areas should be kept toa minimum.
Limitations	Apply in good weather. Temperature of the surface to be coated must be least 3?above the dew point when the humidity is lower than 85%.   In common with all epoxy base coatings, 725-H44-85 will exhibit chalking of the firm on UV exposure.   The dry time and overcoating interval may change according to the environment factors.   Avoiding absorb the solvent steam and paint steam for long time. Skin and eyes must avoid contacting the paint. Pay attention to ventilate and fireproof when applying.
