Water Treatment Coatings & Linings

Coatings and linings for potable water treatment plants

WHAT are Water Treatment Coatings & Linings?

The pipes, storage containers and infrastructure in municipal and industrial water treatment plants are subjected to harsh, damp, and abrasive environments.  Water treatment coatings and linings are applied to these structures to deliver long-lasting protection against spills, corrosion, and chemical attacks while also meeting strict water treatment plant piping coating specifications.

Sherwin-Williams water treatment coatings and linings solutions offer superior chemical, abrasion, wear and tear, impact, and corrosion resistance for steel and concrete storage tanks, pipes, and other infrastructure. If contaminants are spilled or acids come into contact with coated storage containers or pipes, the impermeable surface protects the substrate from damage. Sherwin-Williams coatings and linings prevent corrosion and leaks as well as improve life cycle performance.

  • Extend the total service life of water storage systems
  • Protects against chemical degradation
  • Reduces out-of-service time for critical assets
  • Protects against leaks 
  • Protects against contamination
  • Protects concrete, steel, and ductile iron

Anti-Corrosive & Chemical Resistant Water Treatment Coatings & Linings

Pipes, tanks, storage containers, and other infrastructure in water treatment plants are under constant abuse from wear and tear, heavy impacts, abrasions, and exposure to harsh chemicals. These elements can severely damage concrete, steel, and other materials, causing pipes and tanks to leak or fail, unless they are sealed with a protective coating and lining system.

Sherwin-Williams protective coatings offer:

  • Algae reducing properties to minimize maintenance
  • High-build properties to rehabilitate degraded concrete 
  • Long-lasting asset protection against degradation

Durable Water Treatment Coatings & Linings for a Long-Lasting Finish 

The ideal water treatment coating and lining system is long-lasting, low maintenance, and strong enough to withstand the impacts and abrasions that go hand in hand with the water treatment facility environment. Sherwin-Williams coating and lining solutions are extremely durable and resistant to abrasions and impacts. The exceptional durability of our products reduces the need for touch up and maintenance, making it easier than ever to transport, handle, and install a water treatment coating and lining system.

We also offer algae resistant paint options to inhibit the growth of algae or other microbes in the damp, moist water storage tanks, containers, and pipes of water treatment facilities. Along with our superior edge retention and excellent adhesion, you can install our coating and lining products with the full confidence that they will protect your water treatment plant—and your bottom line—for years to come. Our coating and lining products are easy to clean and low maintenance as well and are suitable for substrates made of concrete, steel, and more.

Sherwin-Williams high performance lining and coating solutions offer excellent durability, chemical resistance, anti-corrosion properties, and low permeability and are designed to extend the lifespan of your water treatment facility.
