"Surface preparation" and "substrate treatment" (substrate adjustment) are often used with similar meanings, but they refer to different tasks in precise terms.
"Substrate adjustment" is the process of transforming the "substrate," which has not been treated with paint or other finishes, into a surface suitable for painting. "Undercoat treatment" is the process of transforming the "undercoat," which has already been painted or treated, into a surface suitable for painting. Both involve the work of "changing the surface of the object to a state suitable for painting," but the conditions before the work is performed are different. Additionally, substrate adjustment is fundamentally based on surface polishing and degreasing, while undercoat treatment also includes the repair of deteriorated surfaces with primer paint or putty. However, in practice, both "substrate adjustment" and "undercoat treatment" are often listed in specifications without distinction! It may be better not to overthink it and to understand both as having the meaning of "transforming into a surface suitable for painting."

basic information
The most important aspects of the painting process are "substrate adjustment" and "undercoating." Both involve transforming the surface of the object to be painted into a condition suitable for painting. Tasks such as "degreasing," "sanding," and "applying putty and primer" are performed to enhance the finish and durability of the paint. Among these, sanding is considered particularly important, and it is necessary to select the appropriate standard based on the current surface condition (degree of deterioration) and expected durability. Harada Iron Works specializes in "blast processing," the most effective treatment method for substrate adjustment and undercoating. We are equipped with large blast and painting facilities, allowing us to handle multiple lots and large items. We have researched "heavy-duty anti-corrosive coatings" that can provide long durability even in harsh environments for metals such as ships and bridges, and we have worked on the painting of many products. Please feel free to contact us regarding blasting and painting. [Factory Tour] Harada Iron Works Blast & Coating Anti-Corrosion Department https://www.nc-net.or.jp/company/98405/product/detail/177785
