Protective coatings specifications for the corrosion protection of assets
“Without a well-designed protective coating specification, problems such as unrealistic bidding, disputes of specific requirements, inappropriate materials or workmanship, delays in completing the work, costly change orders, and increased costs, are likely to occur. Specifications are concise, specific, and contain essential information and requirements.” (NACE 80200/SSPC-TR 4 Joint Technology Report, Preparation of Protective Coating Specifications for Atmospheric Service, NACE International)
Design phase services are centered on the protective coating elements in the project specifications and design drawings to maximize their effectiveness for corrosion prevention, safety, and appearance. Maintenance coating projects may be straightforward regarding the surface preparation and application requirements, but when performed in the context of a functioning plant, facility, or process, the complexity can be magnified by factors such as MOPO procedures, protection of existing assets and workers, waste containment and disposal, coordination with other trades and maintenance work, temporary traffic restrictions, and bypass pumping just to name a few.
New large-scale construction projects add multiple dimensions to the protective coating and lining requirements due to the variety of structural components, equipment, architectural features, and service conditions. It’s not unusual to encounter dozens of different types of equipment and piping systems which need multiple coating systems, some having more than one exposure environment for the same component. In addition to the project specifications the design drawings may also include protective coating annotations for architectural, structural, civil, and mechanical plans. Thorough preparation of room finish schedules, pipe system schedules, limits of coverage for secondary containment and severe corrosion areas, high and low water elevations, and joint and termination details is needed for consistency.
The coating and lining specifications found in Division 09 finishes can refer to, and be referenced by, numerous other divisions depending on the industry and construction project.

Objectives for preparing a protective coating specification
“There are several objectives for preparing a protective coating specification. These include, but are not limited to, the following:
Obtain specific protective coating products or their equals
Assure quality materials and workmanship
Determine inspection requirements
Assure timely completion of work
Obtain reasonable costs that reflect the specification requirements
Avoid costly change orders and claims
Meet safety, environmental, and regulatory requirements of the protective coating operation
Assure suitable coating systems are applied to the correct equipment” NACE 80200/SSPC-TR 4 Joint Technology Report, Preparation of Protective Coating Specifications for Atmospheric Service, 2000 NACE International, https://nace.org
CPC planning is the most efficient method for effectively addressing and reducing the impact of corrosion at every stage of a product or facility’s lifecycle. This eCourse walks through the NACE SP21412-2016/SSPC-CPC 1 standard, diving into the key aspects of CPC planning for products and facilities. It covers: attributes that impact CPC planning; considerations for material selection and design to minimize corrosion; and items that should be addressed in CPC planning which affect CPC in design, fabrication and construction, operation and use, and maintenance and sustainability.
The PCS 1 Basic Principles introduces both the theoretical and practical aspects of using coatings to control corrosion and the economic benefits of managing them. Common corrosion control coatings are def ined and when, how, and where they should be used.
The PCS 2 Advanced course provides advanced level technology topics related to protective coatings. Highlights include an in-depth discussion of coatings, their basic chemical properties, and any unique considerations for their surface preparation, application and inspection. Testing coating properties and performance, common coating defects, substrates, selecting coating systems, the specif ication, and surveys and maintenance planning are also covered.
