• All surface preparation tools/equipment must vacuum-shrouded.

• Coatings must be applied by brushing or rolling.

TABLE 1 - SURFACE PREPARATION METHOD

SURFACE MATERIAL

METHOD REQUIREMENTS

STEEL SURFACES

Abrasive-blasting to SSPC-SP10/NACE No. 2, using grit conforming to MIL-A-22262 (to produce a 1.5 to 2.5 mil anchor profile).

-or- Power tool cleaning to SSPC-SP 11 (to produce a 1.0 mil anchor profile)

ALUMINUM SURFACES

Brush blasting with clean, fine aluminum oxide, garnet or equivalent inert material conforming CID A-A-59316, Type I & IV, to remove all existing coatings and rust spots, down to bare metal (and produce a 1.0-1.5 mil anchor profile).

-or- Mechanical cleaning, using power sanders and abrasive sandpaper with no metallic contents, to remove all existing coatings and rust spots, down to bare metal.

3.4 Substrate inspection. After completion of surface preparation and before non-skid pad application, the Contractor shall perform a visual inspection of the prepared substrate. Submit CFR.

3.5 Slip-resistant sheet installation particulars. The Contractor shall apply new slip resistant sheets as specified for “Weather Deck Slip Resistant Sheets, Option I, Steel” in SFLC Std Spec 6310, Appendix A (Cutter and Boat Exterior Paint Systems). Ensure the following:

• Slip resistant sheet material are applied to within approximately 2 inches of deck fittings and protrusions and to within approximately 5 inches from coaming and deck edges. Deck fittings include, but are not limited to, the following: pad eyes, vent pipes, stanchion sockets, foundations.

• No more than approximately 3 inches separate adjacent pieces on all work and traffic areas.

• Sheets are not applied over raised weld seams, deck fittings and protruding components (including, but not limited to: pad eyes, vent pipes, stanchion sockets, foundations).

• Bottom of hatch surfaces, and areas within two inches of hatches (as applicable).

3.6 Ultrasonic thickness (UT) measurement. The Contractor shall take a total of 100 UT measurements of deck plating, in locations designated by the Coast Guard Inspector, in accordance with SFLC Std Spec 0740, Appendix C. Submit a CIR.
