Commercial water tank projects usually have high needs for performance, longevity, and compliance due to multiple factors like water safety regulations, weather or environmental stress, etc. Whether the Nevadata painting contractors are in charge of tanks that are installed for commercial or industrial buildings or part of a municipal water system, they need to learn essential considerations of these painting projects. In addition, a contractor needs to comply with minimum requirements for undertaking this job. This article discusses key elements of commercial water tank painting projects.
Safety first
Most tank cleaning and coating projects are too risky and require technical skills. Commercial painters in the United States always prioritize safety and risk management. These companies thoroughly train and prepare their painting crews for aerial lift operations and working in confined spaces. Additionally, these contractors monitor on-site safety to ensure workers are safe when doing their job.
Tank condition
The current condition of water tanks is assessed by painters, supported by-
- Years of experience working with concrete and steel water tanks
- Deep coating knowledge, validated through AMPP coating certifications
- Input from professional manufacturers of coatings for marine and water applications.
Surface preparation
A water tank painting project is prone to fail without proper surface preparation, especially the external tanks that are subject to relentless weather forces and harsh environmental conditions. In addition, rust is a routine problem for tanks. If blast cleaning is required, Nevadata painting contractors will provide detailed specifications, including the blasting medium, degree of cleanliness required, particle size, and more.
Suitable coatings
It’s crucial for the water tanks storing portable water to comply with the recommendations of ANSI/NSF Standard 61 for Drinking Water System Components. Standard 61 specifies several elements of water treatment and distribution systems like protective barrier materials such as coatings and paints. Reputed and professional commercial painters are well-aware of such legal requirements and make sure to comply with them.
Coating application
Experienced painting contractors generally coat the exterior surface of water tanks with a three-coat zinc-epoxy-polyurethane system along with a minimum dry film thickness. While interior wet surfaces are usually coated with a three-coat zinc-epoxy-epoxy system approved by NSF Standard 61 for potable water.
Finishing work
Sealers and finishing coats, including the name of the municipality or the name and logo of a certain company, are also part of water tank painting projects. Nevadata painting contractors understand these products and also have experience with templates, branding guidelines, and color specifications when it comes to painting the logo or text on water tanks.
Conclusion
Painting and coating a water tank, especially when on height, is not an easy job. Therefore, always make sure to choose a painting contractor with minimum steel tank cleaning and coating experience, technical coating expertise, regulatory awareness and understanding, exemplary safety record, and ability to meet deadlines. In addition, cleaning and coating water tanks is usually a messy process. So, a painting contractor should be capable of containing debris and other contaminants while considering the protection of nearby areas and buildings. Furthermore, a painting company must ensure the safety of workers and contractors during the job.
