Newbuilding

725-H53-87 should be applied over a recommended primer coating scheme. The primer surface should be dry free from all contamination and 725-H53-87 must be applied within the  overcoating intervals specified (consult the primer data sheet).

Areas of damage should be prepared to the specified standard (e.g Sa2½ or St3 of GB/T 8923.1-2011) and patchprimed prior to the application of 725-H53-87.

Ensure zinc primers are fully cured and the surface is clean, dry and free from contamination and zincsalts before application of 725-H53-87.

Repair

725-H53-87 may be applied directly over aged 725-H53-87 following thorough fresh water washing and degreasing provided the coating to be overcoated is in an intact and tightly  adherent condition. Loose or flaking coatings should be removed back to a firm edge and an appropriate primer should be used to repair the area before application of the full coat.
