The ASTM D4259-18 standard provides a detailed set of operating procedures for surface preparation prior to concrete surface coatings. This treatment is designed to create a suitable surface profile and remove foreign matter and weak flotation on the concrete surface to ensure good adhesion of the coating. The standard applies to concrete surfaces where coating performance needs to be maintained under various conditions of use, including soaking, temperature cycling, or mechanical loading. The standard does not cover all safety-related issues, and users need to establish appropriate safety and environment practices based on the actual situation.
