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.

 Newbuilding:

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 St3GB/T 8923.1-2011using power tool.

Apply 725-WH53-80 before oxidation occurs. If oxidation has occurred, the entire oxidized area should be reblasted to the standard specified above.

Repair/On Board Maintenance:

The areas to be repaired should be cleaned to P St3  GB/T 8923.2-2008  by mechanical method or higher level of surface prepared to P Sa2.5  GB/T 8923.2- 2008by abrasive blasting. Abrade the area immediately surrounding the repair to provide a key for subsequent coating application. Overlap areas should be kept to a minimum.

Limitations:

1)The suitable temperature for applying 725-WH53-80 is 10--35℃.

2)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%.

3)It must be ventilate above 8h at pool ventilation area.

4) The dry time and overcoating interval may change according to the environment factors.

5)Forbid to trample or pollute the surface of 725-WH53-80 and coat the next paint before the film is hard dry.
