Removing "Navy G" Non-Skid Deck Coating

Anti-Skid or Non-Skid coatings are applied to many different surfaces, including ship decks, industrial work areas, steps, catwalks, and other areas where good footing is essential. These coatings frequently combine the toughness of a high solid epoxy or polyurea, and a material to roughen the surface, like an abrasive grit. When the surface is properly prepped prior to coating application, the result is typically a well-bonded, durable surface that prevents slips by personnel and equipment.

The U.S. Navy specifies MIL-PRF-24667C for their non-skid system to be used on weather decks, flight decks, and hangar decks of ships and amphibious vehicles that have aviation capabilities (like aircraft carriers). This coating is commonly referred to as “Navy G” which is a high solid epoxy, and is applied at a minimum of 30-45 Mils thick, depending on the specification.

This thick, well-bonded coating can be very time consuming to remove if a repair on the deck below the coating is needed, or it it’s reached the end of it’s life. Sponge Blasting can be used to remove Navy G non-skid coatings quickly compared to needle gunning, grinding, or ordinary abrasive blasting.
