Why Protective Coatings Matter in Water & Wastewater
Using advanced protective coatings for tanks, pipes, and other water systems is nonnegotiable because the coating provides:
Durability in Harsh Environments Water and wastewater infrastructure is constantly exposed to moisture, chemicals, and biological activity. Protective coatings form a resilient barrier that prevents concrete and metal from deteriorating, extending the life of critical assets. | Corrosion and Chemical Resistance Hydrogen sulfide, chlorides and other aggressive substances can accelerate corrosion in untreated surfaces. High-performance coatings resist these attacks, preserving structural integrity and reducing costly repairs. |
Abrasion and Wear Protection Pumps, sediment flow, and operational traffic can gradually wear down unprotected surfaces. Coatings provide a tough, abrasion-resistant layer that safeguards against everyday mechanical stress. | Compliance with Safety and Regulatory Standards Potable water and wastewater systems must meet strict regulatory requirements. Protective coatings help facilities comply with these standards while maintaining safe and reliable operations. |
Reduced Maintenance and Operational Downtime By preventing damage and deterioration, coatings reduce the need for frequent maintenance. | Fast Return to Service Many polyurea systems cure rapidly compared to traditional epoxies or urethanes, allowing facilities to avoid operational disruption. |
Application Areas of Water & Wastewater Coatings
Marvel Coatings' water and wastewater solutions are used in a wide range of environments, including:
Water Treatment Facilities Coatings protect tanks, basins, and equipment from constant moisture, chemical exposure, and abrasion, guaranteeing reliable operation. | Wastewater Processing & Conveyance Systems Protective layers safeguard channels, pipes, and processing equipment from corrosion, biological activity, and chemical attack. |
Potable Water Tanks & Pipelines Specialized coatings maintain water quality and prevent contamination while extending the service life of tanks and piping. | Concrete Tanks, Walls, & Manholes Seamless coatings prevent moisture infiltration and structural degradation, keeping concrete assets strong and durable. |
Sewage Collection Systems Coatings resist hydrogen sulfide and other corrosive elements common in sewer systems, protecting metal and concrete surfaces. | Water Towers & Storage Vessels UV-stable and chemical-resistant coatings preserve structural integrity and prevent leaks in elevated and exposed storage structures. |
Lift Stations, Wet Wells & Wet Infrastructure Robust coatings provide abrasion resistance and corrosion protection in areas frequently exposed to water, sludge, and operational wear. | Pump Stations & Mechanical Equipment Protective coatings shield pumps, valves, and mechanical systems from corrosion, chemical exposure, and wear, ensuring consistent performance and longer service life. |

How It Works: Application & Support
Marvel collaborates with applicators to match coatings, primers and equipment to the job:
Assessment & Product Selection – Review of asset conditions and performance requirements.
Surface Preparation Planning – Recommendations for reliable long‑term adhesion (mechanical profiling, cleaning, etc.).
Coating Application – Use of mobile spray rigs and appropriate polyurea systems for protective coverage.
Technical Follow-Up – Post-application support and troubleshooting to optimize results.
Compliance Water Standards
Marvel Coatings works closely with customers and applicators to choose the right protective solutions for each water or wastewater project. Certain polyurea formulations can be engineered for potable water applications, but exact certifications (NSF/ANSI or other local standards) should be confirmed with a Marvel technical representative prior to specification.

FAQs
Can protective coatings help manage microbial growth or surface biofilms?
While coatings aren't antimicrobial treatments, they can smooth surfaces and reduce areas where biofilms can attach, making cleaning easier. Marvel can advise on appropriate products and maintenance techniques.
Are there coatings suitable for environments with thermal cycling or freeze-thaw conditions?
Yes, polyurea coating that offers flexibility and adhesion across temperature ranges helps prevent cracking. Marvel's polyurea systems are produced to maintain performance despite thermal stresses.
What environmental conditions should be considered before applying a protective coating?
Factors like temperature, humidity and surface moisture can affect coating adhesion and cure. Marvel technical support helps plan application timing and conditions for successful results.
Do industrial coatings change the dimensions of pipes or equipment?
Coatings add only a thin film thickness. They do not significantly alter dimensions in most cases. Marvel makes sure product selection meets performance needs without interfering with pipe fit or clearances.
Can coatings be applied underwater or in saturated environments?
Most systems require dry surfaces, although some moisture-tolerant coatings perform better than others. Marvel's technical team can review project conditions to recommend appropriate products and methods.
How long does a typical water/wastewater coating system last?
Lifespan varies depending on environment and use, but properly selected and applied pure polyurea systems outperform conventional coatings, providing years of service with minimal maintenance.
