A hot dip-galvanized coating is said to be fully weathered when the exposed surface consists mainly of water-insoluble zinc carbonates, some zinc oxides, and rarely, zinc hydroxides. Usually occurring around after six months of weathering, a finely etched and roughened profile acceptable for paint covers the surface of the galvanized coating. After all oil and grease has been removed with the methods of another surface preparation standards, cleaning with a waterjet according to SSPC-SP12 will remove all lose particles and leave the finely etched surface previously described. D7803 specifically calls out this standard with a condition that the water pressure be below 1450 psi. D6386 describes the same process, but without mentioning the surface preparation standard.
New SSPC/NACE wet abrasive blast cleaning (WAB) standards were approved in August 2015. The standards define five degrees of cleaning that are created using a mixture of abrasive and water. The mixture is created in one of three ways: water is injected into the dry abrasive blast stream, abrasive is injected into a pressurized water stream, or an abrasive/water slurry is propelled through the blast hose.
NOTE: Flash rust is not included in the dry blast standards since the surface remains dry for the entire process. The dry blast standards discuss freedom from rust back (re-rusting), which is rusting that forms when dry blast cleaned steel is exposed to moisture, contamination, or a corrosive atmosphere. The dry blast standards require the removal of visible rust that forms on the surface after cleaning (i.e., removal of the rust back).
Surface preparation can account for up to 40% of a painting project and understanding what minimum finish is required will keep costs to a minimum and provide optimal paint adhesion. The SSPC standards are designated as SSPC SP2 or SSPC SP3 while NACE uses a simple numerical code. A few years ago, the SSPC and NACE standards were modified to coincide.
Construction, maritime, manufacturing, oil and gas, infrastructure, and transportation are just a few of the sectors where SSPC standards are used. Engineers, builders, inspectors, facility managers, and coating producers among others use these requirements. Each standard addresses a particular need, ensuring that surfaces are suitably prepared based on elements including substrate type, coating type, exposure circumstances, and desired coating lifespan.
Imagine a bridge in a coastal area that is exposed to corrosive saltwater and erratic weather patterns. Engineers responsible for maintaining this vital infrastructure will consult SSPC standards to choose the best techniques for surface preparation. They may decide to use abrasive blasting in accordance with SSPC-SP 10 to achieve near-white metal cleanliness, depending on the severity of the corrosion and the desired coating longevity. This rigorous prepping guarantees that the protective coatings applied later will adhere well, preventing corrosion and extending the lifespan of the bridge.
The evolution of the requirement for thorough surface preparation standards may be seen in the history of SSPC, from its beginnings as a steel structure painting council to its current position as the Society for Protective Coatings. Modern protective coating procedures are supported by these standards, which are the result of years of experience and knowledge in several industries. SSPC makes sure that substrates are painstakingly cleaned in order to get coatings that will stand the test of time through the use of water jetting, solvent cleaning, power tool cleaning, and abrasive blasting.
The SSPC continues to play a crucial role in influencing how industries handle surface preparation as we stand on the verge of new technology developments and challenges. Professionals protect their investments, lower maintenance costs, and increase the longevity of vital infrastructure and assets by upholding these standards. The SSPC surface preparation standards continue to be a source of inspiration in a world where resistance to corrosion and deterioration is of utmost importance, ensuring that surfaces are not only suitably coated but also ready to endure the test of time.
AMPP SCs are responsible for the generation, publishing, and maintenance of all AMPP products that require a consensus-driven process, including standards, technical reports, guides, and qualification procedures dealing with materials selection and their protection against corrosion.

Corrosion control is a serious issue. Because of the serious repercussions brought by improper corrosion management, some industry experts formed a group that aims to raise the standards of professional corrosion control. The group also aims to increase awareness on the proper methods and effects of quality corrosion control. With the interest of upbringing corrosion management practices as the top priority, The Society of Protective Coatings was born.
By adhering to the strict practices and standards presented by SSPC Houston as well as employing SSPC-certified corrosion protection experts, Cor-Pro Systems offers nothing but superior quality corrosion protection products and services to industries Houston, TX and other areas in the Gulf Coast area.
