Exterior surfaces of storage tanks and reservoirs


When choosing a paint system, several factors need to be considered:

• the corrosion category of the environment
• the material (substrate) to be painted
• the coating costs over the whole service life of the object.


In cases of heavy stress, such as marine climate, systems with a zinc-rich epoxy primer are recommended.
Topcoats of the paint system should have good weather resistance and gloss retention. The Tikkurila range has high-performance polyurethane paints with excellent resistance to weather and mechanical stress.
