The coatings covered by this specification are intended for use on general (walking) deck areas (Types I, II, III, IV, V, VI, VII, VIII, IX, and X composition G), the flight and hangar decks of aircraft carriers (Types I, II, V, VI, VII, VIII, and IX compositions G and L) and on the landing decks of air-capable amphibious aviation and aviation ships (Types I, II, III, V, VI, VII, VIII, and IX composition G). Type I provides longer durability than Type II, however the factor of increased weight should be considered when using this system. Type V provides longer durability than Type I, but attention is given to the significantly shorter pot life. Type VI is a fast curing non-skid material for use when application windows are limited. Type VII is a temporary repair non-skid that is ready for service in 24 hours, however, it may have a relatively short service life making it unsuitable for normal non-skid installations. Type VIII is intended for application at low temperatures, but it should not be considered a fast cure product for application at normal or elevated conditions. Type III non-skid systems are intended for use where flexibility or thick smoothing capability is needed to correct drainage. Type III is not intended to be used on aircraft carriers if the underlayment is used due to compressibility of the materials under heavy aircraft. Type IV can be used on walking surfaces, but is not intended for aircraft landing decks. Although laboratory testing is done between 2 °C (35 °F) and 32 °C (90 °F), each individual coating of these coating systems is applied in the fleet between 4 °C (40 °F) and 49 °C (120 °F).
