scope:

This standard provides requirements for the field application of polyurea, polyurethane, or polyurea/polyurethane hybrid thick film coatings to concrete, steel, and non-ferrous metal surfaces using plural component spray equipment. In this standard, thick film coatings are defined as coatings specified to have greater than 500 micrometers [μm] (20 mils) dry film thickness. Surface preparation, pretreatments, machinery requirements and parameters are addressed in this standard.

UNITS OF MEASURE:

This standard makes use of both the IEEE/ASTM SI10, International Standards (SI) units and U.S. Customary units. The measurements are not exact equivalents; therefore, each system must be used independently of the other without combining in any way.
