The quality of a coating application is fundamentally determined by the condition of the surface it is applied to. Surface preparation is a foundational phase but a essential element that controls the sustained performance, functionality, Tehran Poshesh and attachment integrity of coatings. Without proper surface preparation, the highest-grade protective coatings can break down before their expected lifespan, leading to expensive remediation, potential risks, and shortened service life of the coated structure.

Surface profiling involves cleaning, degreasing, and often texturing the substrate to create an optimal environment for the coating to bond. Contaminants such as oil, grease, dust, rust, moisture, and old paint residues serve as isolating layers between the coating and the substrate.
