3.3.1 Pre-surface preparation wash. Prior to accomplishing surface preparation, accomplish low-pressure (less than 5,000 psi) fresh water wash of all affected surfaces, to remove soluble chlorides and other surface contaminants. Capture, contain, and dispose of wash water for proper disposal in accordance with all Federal, state and local regulations.

3.3.2 Surface preparation and coating application. Prepare and coat the deck surfaces designated in paragraph 1.1 (Intent), including bitt and chock foundations, machinery rack guards and machinery foundations, hatches and hatch guards, stanchion sockets, vent pipes, angle coaming area, and approximately six inches up all adjacent vertical surfaces (as applicable); use the system specified for “Weather Decks, Non-Skid, MIL-SPEC Coating for Steel or Aluminum”, in SFLC Std Spec 6310, Appendix A (Cutter and Boat Exterior Painting Systems).

3.3.2.1 Substrate inspection. After completion surface preparation and before coating application, perform a visual inspection of the prepared substrate. Additionally, take a total of 100 UT measurements of plating and associated structural members in locations designated by the Coast Guard Inspector, in accordance with SFLC Std Spec 0740, Appendix C. Submit a CFR. CFR must include recommendations for plating renewals for all plating and structural members corroded more than 30% of original steel thickness.

3.3.2.2 Color selection. Select and use Dark Gray (36076) as the finish/top coat color.

The Contractor may add abrasives to the waterjet stream, for one or both of the following reasons:

· Achieving greater productivity.

· Achieving the required surface profile.

CAUTION!

Waterjetting without abrasive addition does not provide any additional anchor profile to the surface, beyond what was present after the previous surface preparation. Abrasive may be introduced to the waterjet stream, to achieve required surface profile and/or greater productivity. Abrasive blast grit (if used for preparing the aluminum surfaces) must conform to CID-A-A59316, Type I or Type IV.
