This specification covers a hot-applied coal tar painting system for underground and underwater steel structures, consisting of a primer and two hot-applied coats.

This system is suitable for use on parts or structures exposed in Environmental Zones 2C (fresh water immersion), 3B (chemical exposure, neutral), and 3C (chemical exposure, alkaline). It has good abrasion resistance. It is also suitable for underground use. It must be used with discretion for immersion in corrosive chemicals since the coating is dissolved by some organic solvents and attacked by oxidizing solutions.

The coal tar enamel must be topcoated with coal tar emulsion when exposed to sunlight to prevent checking and alligatoring.
