ASTM D5107-03(2007)

Standard Practice for Preparatory Surface Cleaning of Architectural Sandstone

SCOPE
1.1 This practice covers non-abrasive surface cleaning of architectural sandstone to remove grease, dirt, loose material, and surface deposits such as soot, fly ash, hydrocarbon residues, and algae and other biological growth in preparation for the application of water repellent coatings. Procedures include broom cleaning, vacuum cleaning, air blast cleaning, water cleaning (and detergent water cleaning), and chemical cleaning.
1.2 Limitations - This practice is intended to clean architectural sandstone without damaging it or altering the surface profile. These procedures are not intended for interior stonework. Where work on surfaces of artistic, architectural, cultural, or historic significance is being considered, guidance from specialists should be sought.
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
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 4.

5. Procedure
5.1 Air blast, water, scrubbing, sweeping, or vacuuming are acceptable cleaning methods. Chemical cleaning agents may be
used to remove surface deposits such as soot, fly ash, and hydrocarbon residues not removed by any of the above methods.
Chemical cleaning should be preceded and followed by a thorough fresh water rinse.
5.2 Existing conditions of the substrate will determine the selection of appropriate procedure(s). Prior to the initiation of
cleaning, small test areas should be cleaned in inconspicuous areas by the selected procedure to determine effectiveness.
5.3 The six types of cleaning procedures are described below. One or more of the procedures may be required to remove
contaminants from the sandstone surface:
5.3.1 Broom Cleaning—Removes most loosely adherent solid contaminants.
5.3.1.1 Working from top to bottom, sweep the surface with a clean industrial stiff-bristled broom or similar device. Remove
sweepings from the immediate work area.
