SSPC Sets Wastewater Coating Standard
Performance requirements for certain concrete coatings used at wastewater facilities are the focus of a new standard by SSPC: The Society for Protective Coatings.
SSPC-Paint 44, "Coatings for Concrete Wastewater Structures," establishes minimum performance standards for liquid-applied organic polymeric coatings and linings used over concrete in municipal wastewater facilities. The standards are based on categories of service environments and structures within the facility.
The new standard was developed for wastewater facility owners and specifiers and manufacturers of wastewater coatings.
SSPC-Paint 44 can be purchased through the SSPC Marketplace here.
Determining Requirements
Once the specifier identifies the structure to be coated, performance requirements for coatings for the structure's service environment can be determined based on a table included in the standard.
The notes include an example of language that could be used to specify coating requirements from the standard.
According to SSPC, the standard is necessary because of:
Concrete structures in wastewater treatment plants are exposed to more severe service environments than in the past, and protective coating systems that had performed successfully for many years may no longer provide adequate protection, resulting in frequent coating failure and rapid concrete degradation, SSPC says.
The standard was developed by SSPC Committee C.1.13, Coatings for Wastewater Facilities.
About SSPC
Founded in 1950, SSPC is a nonprofit association focused on the protection and preservation of concrete, steel and other industrial and marine structures and surfaces through the use of high-performance coatings.
SSPC provides information and standards on surface preparation, coating selection, coating application, environmental regulations, and health and other issues that affect the protective coatings industry.
