There are many different types of coatings that can be used for the interiors and exteriors of tanks. Interior tank linings are often highly specialized according to the contents of the tank, and must be applied by contractors with excellent product knowledge.

Exterior tank coatings are generally protective in nature. Waterproofing and corrosion resistance are main qualities for exterior tank coatings. For outdoor tanks with temperature-sensitive contents, reflective or UV protective top coatings should be used. Epoxy coatings with polyurethane top coats are typically exceptional choices here, as epoxy resin is a durable material that withstands abuse and polyurethane protects from UV damage.
