Sherwin-Williams Water and Wastewater System Coatings Guide
Sherwin-Williams is known for providing high-performance coatings, particularly in industries like water and wastewater treatment, where protective coatings play a crucial role in preventing corrosion and ensuring the longevity of structures.
In water and wastewater systems, the materials and structures (like potable water tanks, pipes and treatment facilities) are exposed to harsh environments including moisture, chemicals and fluctuating temperatures. Coatings must be designed to withstand these elements, which is why we specify formulations based on the type of structure and the environmental conditions.
Our Guide to Water and Wastewater Coating System Solutions
Sherwin-Williams has a Water and Wastewater System Guide that takes the guesswork out and provides coating system solutions while considering durability and chemical resistance, corrosion prevention, environmental considerations, application methods and curing, and standards and compliance.
Durability and Chemical Resistance
In water and wastewater systems, durability and chemical resistance are critical factors for protective coatings. Chemicals commonly found in these environments, such as chlorine, sulfur and hydrogen sulfide gas, can significantly damage unprotected substrates. If not properly shielded, these aggressive compounds can lead to rapid degradation of materials like steel, concrete and other structural components. Protective coatings are specifically formulated to resist these chemicals, preventing corrosion, pitting and other forms of damage. By providing a durable barrier, these coatings help extend the lifespan of infrastructure, ensuring long-term performance in harsh, chemically active environments.
Corrosion Prevention
Corrosion prevention is crucial for structures like metal pipes, potable water tanks, clarifiers, digesters and wastewater treatment facilities, which are vulnerable to corrosion from chemical exposure and constant immersion. Sherwin-Williams protective coatings provide an effective barrier, preventing direct contact between metal or concrete substrates and corrosive elements, thereby extending the lifespan and integrity of these critical infrastructure components.
Environmental Conditions
Sherwin-Williams protective coatings are designed to withstand the challenging environmental conditions often encountered in water infrastructure. These coatings provide superior protection against moisture, chemical exposure and temperature fluctuations, all of which can accelerate corrosion and degrade structural integrity. Whether for potable water tanks, wastewater treatment plants or pipes, Sherwin-Williams coatings offer long-lasting durability, ensuring the resilience of infrastructure even in harsh, wet environments. This helps to maintain system performance, reduce maintenance costs and extend the life of critical assets.
Application Methods and Curing
Different protective coatings might require specific application techniques (spray, brush or roller), as well as curing processes (induction time, heat or moisture cure), depending on the structure and the environment.
Standards and Compliance
Sherwin-Williams’ guide will specify various protective coatings that comply to various industry standards such as NSF/ANSI 61 (Drinking Water System Components- Health Effects) and ASTM G210 (Standard Practice for Operating Severe Wastewater Analysis Testing Apparatus), to ensure that the coatings are safe for use in water treatment and wastewater structures.
