    Sandability

    Overview Products Standards Terms
    Grindability refers to the ability of a coating surface to remain smooth and maintain adhesion after grinding. The principle involves removing uneven parts of the coating surface through mechanical friction, with the purpose of providing a good substrate for subsequent coatings. This process is applied in procedures requiring multi-layer coatings, such as wood coatings and automotive refinish paints.
    Selection
    When selecting sandability, consider coating hardness, grit coarseness of sanding tools, and environmental humidity during construction. Use fine sandpaper for hard coatings and coarse sandpaper for soft coatings; choose fast-drying materials in high humidity conditions. During testing, sand with standard sandpaper and inspect surface uniformity and dust condition.
