One coats AMERCOAT 138 HR Non Skid(with roller) @ 30 sq ft/gal Note: Before the start of production application of any non-skid coating, a test patch will be applied. This test patch will be acceptable to the MSCREP and will stand as the texture and profile standard for the entire job. 5. Apply the following paint system for all markings: Two coats AMERCOAT 929 White @3-4 mils DFT Follow the marking instructions specified in the ship?s drawings, Shipboard aviation Facilities Resume, and a sketch made specifically from the deck prior to any surface removal. 6.
