Specification Feedback

The intent of this section is to inform all users that a spec feedback mechanism is in place, and is located on the MLCA Naval Engineering Division’s website. Spec feedback is a very important part of our overall continuous improvement process, and is crucial to specification development. It will allow spec writers to capture all specification-related lessons learned, and avoid mistakes or ambiguities in follow-on availabilities.

All feedback will be reviewed, evaluated, and responded to in a timely manner.

If you have access to the CGWeb (Intranet), please use the following link, which will connect you to the MLCA(v) Naval Engineering website, for submitting your feedbacks:

http://webapps.mlca.uscg.mil/vdiv/specifications/feedback/defaul t.cfm

If you do not have access to the CGWeb (Intranet), you may still submit your feedbacks, using the following web link:

Ensure all coatings are in compliance with COMDTINST M10360.3, Appendix C.

CHECKPOINT 2 - PAINT STORAGE

Ensure all coatings are kept at a temperature of 65 to 85°F at all times, unless otherwise specified by the coating manufacturer(s).

CHECKPOINT 3 - AMBIENT CONDITIONS

Ensure surface and surrounding temperatures are each between 50 and 90°F for water-based coatings, and 35 and 95°F for other coatings, unless otherwise specified by the coating manufacturer(s).

Ensure surface temperature is at least 5°F above the dew point, unless otherwise specified by the coating manufacturer(s).

CHECKPOINT 4 - PRE-SURFACE PREPARATION

Remove surface contaminants (soluble salts, loose rust, mud, and marine growth) with low pressure fresh water wash down

(maximum 5,000 psi). If oil and grease are present, perform solvent cleaning, as per SSPC SP-1.

CHECKPOINT 5 - SURFACE PREPARATION

Verify environmental conditions (see CHECKPOINT 3).

Verify final system dry film thickness.

Verify system cure for service resumption - U/W Body surfaces: 5-8 hours @ 77 degrees F; Potable water tanks: 7 days @

77 degrees F.

Ensure potable water tank exhaust ventilation is maintained continuously from and during coating application through final system cure (minimum 7 days @ 77 degrees F.), to exhaust all solvent to the atmosphere and to prevent solvent entrapment.
