Water Storage Coatings & Linings

Coatings and linings for potable water storage tanks 

WHAT are Water Storage Coatings and Linings?

Potable water tanks, pipes, pressure vessels, filters, water towers, ground storage containers and other infrastructure in municipal, industrial or commercial water storage facilities undergo constant abuse from environmental attacks, contamination, chemical exposure, leakage and corrosion. Without the application of internal linings and external coatings to protect the concrete or steel substrate, these elements can cause significant and costly damage. These coatings and linings must be designed to meet strict regulatory standards for potable water while also offering additional resistance to damage, contamination and leaks.

Sherwin-Williams drinking water tank coating and lining solutions are anti-corrosive, chemical resistant, durable options for water treatment facilities. Our NSF/ANSI 61-approved epoxy and polyurethane potable water storage coatings and linings are built to protect water tanks, piping and valves made from steel or concrete. Install Sherwin-Williams water storage coatings and linings to seal gaps, create an impermeable barrier, achieve superior corrosion protection, resist chemical damage and support clean water delivery goals.

Our potable water tank linings and coatings offer a wide range of benefits:

  • Extends 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 and Chemical Resistant Water Tank Linings and Coatings

Water tanks, pipes, filters, valves and containers are susceptible to corrosion and other stresses that weaken and deteriorate concrete and steel, unless the substrate is covered with a protective paint or sealer. Applying Sherwin-Williams water tank linings and coatings creates a durable, thick film that prevents corrosion and leaks, ensuring the potable water system components remain safe and sanitary.

Sherwin-Williams protective coatings offer:

  • Solutions to maximize sustainability goals
  • Edge retention properties for added protection on difficult surfaces   
  • Proven results for long-lasting service life expectations

Water Storage Linings and Coatings for a Low Maintenance, Long-Lasting Finish 

Sherwin-Williams potable water storage NSF/ANSI 61 (600)-approved polyurethane and epoxy tank lining and coating solutions are extremely durable as well as resistant to abrasions, mud cracking, impacts, corrosion, chemicals and wear and tear. They are designed to be easy to apply and recoat as needed and have quick curing times. Combined, these features ensure our coating and lining systems are easy to maintain. When you install Sherwin-Williams coatings and linings in your water storage facility, you can expect to return to service fast.

Thanks to their superior strength and resistance, our water tank sealers, coatings and linings offer long-lasting protection. Once applied, they will continue to seal, protect and enhance the durability of your water tanks, pipes, filters, valves, containers, water towers and other potable water storage infrastructure for years to come.
