Quality Management on Coating Adhesion of Floor Paint Engineering Sub-project

The coating adhesion of epoxy floor paint is a key indicator of coating engineering quality. However, there are no proper clauses in the national construction specifications and quality inspection evaluation standards for testing the adhesion of epoxy floor paint coatings.

Coating adhesion serves as the foundation for the service life of epoxy floor projects. Although coating thickness is related to service life, there is no fixed proportional relationship between them. When other influencing factors conform to objective rules, an appropriate increase in coating thickness helps extend the service life.

Regardless of whether the standard is set high or low, this is a professional industry standard that clearly specifies the testing requirements for coating adhesion.

Quality defects of floor paint coating works include immediate visible problems such as sagging and missing brushing after completion, as well as latent faults appearing several months or one to two years later, such as blistering and peeling. These hidden problems often do not show up during project acceptance, yet they essentially reflect poor coating adhesion and constitute the core quality risk of floor paint projects.
