Systems and Compatibility:

Consult your Representative for the systems best suited for the surfaces to be protected.

Surface Preparation:

All surfaces to be coated should be clean, dry and free from contamination.

Primed Surfaces

The primer surface should be dry free from all contamination and 725-S52-60must be applied within the overcoating intervals specified (consult the relevantproduct data sheet).

Areas of breakdown, damage etc., should be prepared to the specified standard (e.gSa2.5（GB/T 8923.1-2011）or Abrasive Blasting, or Power Tool Cleaning) and patchprimed prior to the application of 725-S52-60.

Repair

725-S52-60 should be applied over a recommended primer coating scheme. The primer  surface should be clean, dry and free from contamination. Areas of breakdown, damage etc. should be prepared to the specified standard (eg. Sa2.5) and primed prior to the application of 725-S52-60.

725-S52-60may be applied directly over aged 725-S52-60 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.
