Industrial Protective Coating Systems for Michigan Facilities
Protective coatings are the primary defense against corrosion, chemical attack, and mechanical wear on the steel structures and equipment that Michigan industrial facilities depend on. Endurance Painting has applied industrial protective coating systems throughout Metro Detroit and Southeast Michigan for over 35 years — from maintenance painting on in-service structural steel to high-build epoxy systems on chemical-exposed surfaces to full three-coat zinc/epoxy/urethane systems on new construction. We select coating systems based on the specific exposure environment and performance requirements of each application, not simply what is available or familiar.
The most common industrial protective coating systems we apply are built around three layers, each serving a distinct function. The zinc-rich primer provides cathodic protection to the steel substrate by sacrificially corroding in the presence of moisture, protecting the underlying steel even where the coating film is damaged. The epoxy intermediate coat provides barrier protection — a dense, chemically resistant film that blocks moisture, oxygen, and corrosive agents from reaching the primer and substrate beneath. The urethane or alkyd topcoat provides UV resistance, color, and gloss for aesthetics and a final layer of environmental resistance. Applied correctly at the specified film thickness on properly prepared steel, this system delivers years of reliable protection in even demanding Michigan industrial environments.
Beyond the standard zinc/epoxy/urethane system, we apply specialty coatings for specific industrial applications: 100% solids epoxy for immersion service and chemical tanks, novolac epoxy for highly aggressive chemical environments, high-build polyamide epoxy for exterior industrial structures, moisture-cure urethane for steel surfaces where condensation prevents application of moisture-sensitive products, and dryfall ceiling coatings for warehouse and factory ceilings. Our knowledge of coating chemistry and product selection allows us to match the right system to the right application on every project.
Epoxy Coating Systems
High-build polyamide epoxy, 100% solids epoxy, and novolac epoxy systems for barrier protection, chemical resistance, and abrasion resistance on industrial steel and concrete surfaces.
Urethane Topcoats
Aliphatic urethane topcoats for UV stability, color retention, and gloss on industrial structures — the preferred finish coat in three-coat industrial protective coating systems.
Zinc-Rich Primers
Inorganic and organic zinc-rich primers for cathodic corrosion protection of structural steel in industrial and outdoor exposure environments across Michigan.
Chemical-Resistant Coatings
Novolac epoxy, polyurea, and specialty chemical-resistant coating systems for surfaces in contact with acids, caustics, solvents, and other corrosive industrial process chemicals.

Coating System Selection & Application Expertise Built Over 35 Years
The difference between a protective coating that lasts 5 years and one that lasts 20 years is usually not the brand of paint — it is the quality of surface preparation and the correctness of the coating system selection for the environment. Endurance Painting's 35+ years of protective coating experience in Michigan's industrial sector has taught us that cutting corners on surface prep or using the wrong coating system costs facilities far more in premature failure and recoating expense than doing it right the first time.
Our approach to protective coating projects starts with understanding the exposure environment: is the steel interior or exterior? What temperature range does it experience? Is there chemical splash or immersion? What level of humidity and condensation does the structure see? Is the coating aesthetic or purely functional? These questions determine the system recommendation. We follow coating manufacturer application guidelines strictly — applying at the specified wet film thickness to achieve the required dry film thickness, maintaining proper recoat windows between coats, and monitoring temperature and humidity conditions during application.
We use plural-component spray equipment for two-component epoxy and urethane systems, which ensures the correct mix ratio is maintained at the spray tip throughout the application — a critical factor in the cure and performance of two-component coatings. Our crews are trained in the operation and maintenance of plural-component equipment, and we verify mix ratio and spray settings at the start of each application. We carry the insurance, SSPC certifications, and safety documentation required by Michigan industrial facilities that specify protective coating work.

Frequently Asked Questions
What is the difference between epoxy and urethane coatings?
Epoxy coatings are two-component systems that cure by chemical reaction, producing a hard, dense film with excellent adhesion, chemical resistance, and abrasion resistance. They are commonly used as primer or intermediate coats in industrial systems. Urethane (polyurethane) coatings are also two-component systems but are formulated for superior UV resistance, color retention, and gloss — making them the preferred topcoat in three-coat industrial systems where appearance and exterior durability are important. Together they form the backbone of most industrial protective coating specifications.
When should zinc primer be used?
Zinc-rich primers should be used on structural steel in environments with significant corrosion risk — industrial interiors with high humidity, chemical exposure, or condensation; all exterior steel structures; and any steel that will be subject to ongoing moisture exposure. The zinc provides cathodic (sacrificial) corrosion protection to the steel substrate, corroding preferentially to protect the underlying steel even where the coating film is damaged.
How long do industrial protective coatings last?
The service life of an industrial protective coating system depends on the coating system applied, the quality of surface preparation, the thickness of the applied film, and the severity of the operating environment. A properly specified and applied three-coat system on blast-cleaned steel in an industrial interior typically lasts 10 to 20 years. Exterior systems in Michigan's climate typically require maintenance recoating on a 7 to 15 year cycle. Single-coat maintenance paints have shorter effective lives and require more frequent recoating.
Do you use plural-component spray equipment?
Yes. Many industrial epoxy and urethane coating systems are two-component materials that require mixing at a precise ratio at the spray gun tip — known as plural-component or proportioning spray equipment. This equipment ensures the correct mix ratio is maintained throughout the application, which is critical for proper cure and performance of the coating. Endurance Painting owns and operates plural-component spray equipment and our crews are trained in its operation and maintenance.
