ITEM 15.0 CABIN TOP REPAIRS, PAINTING, GEL-COAT

15.1 Scope of Work:

15.1.1 Preparation: The Contractor shall remove all through cabin fasteners/stuffing tubes, with the exception of the main cabin bolts. The stuffing tubes that are removed shall be replaced using cable clams.

The main cabin bolt heads shall be covered to prevent gel-coating. All holes not utilized for thru hole fasteners/fittings shall be filled with a commercial grade fiberglass filler. The entire surface of the cabin including exhaust vents shall be sanded to provide a 1.25 anchor pattern. No part of the main cabin shall be sand blasted. The interior of the cabin shall be protected at all times from exterior contaminants.

15.3 Fiberglass, gel-coat and paint:

15.3.1 The contractor shall sand the cabin tops to provide a 1.25 mil anchor pattern. The cabin tops shall be cleaned to remove all foreign articles. Then 2 coats, 2 mils MDFT each Top Coat, Awlgrip Dark Gray shall be applied by spray application. The contractor shall conduct the MDFT test in the presence of the COTR.

15.3.2 The contractor shall sand all white work on cabin to provide a 1.25 anchor pattern. The contractor shall apply two (2) coats, 5 mils MDFT of high Gloss White gel-coat by spray application to the entire cabin surface with exception of cabin tops, that produces a high gloss finish.

The main cabin bolt heads shall be covered to prevent gel-coating. All holes not utilized for thru hole fasteners/fittings shall be filled with a commercial grade fiberglass filler. Any paint shall be removed from existing gel-coat by sanding.

15.3.3 All through cabin fasteners/fittings shall be replaced using cable clams. The contractor shall apply

Sika Flex caulk or an equivalent marine grade caulking to each fastener/fitting as it is installed.

The contractor shall conduct a leak test in the presence of the COTR.

15.4 Contractor and COTR Check Points:

15.4.1 Witness surfaces prior to fiber glassing.

15.4.2 Witness surface prior to painting.

15.4.3 Witness the MDFT test.

15.4.4 Witness the surface prior to gel-coating.

15.4.5 Witness the leak test.
