ASTM D4259-88(2012)

Standard Practice for Abrading Concrete

SIGNIFICANCE AND USE
This practice is used to prepare concrete for coatings where optimum bond is desired for service conditions such as continuous or intermittent immersion, temperature cycling, or mechanical loading.
SCOPE
1.1 This practice includes surface preparation of concrete to prepare the surface prior to the application of coatings.
1.2 This practice is intended to alter the surface profile of the concrete and to remove foreign materials and weak surface laitance.
1.3  This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see Section 5.
