SSPC Revises Concrete Surface Prep Standard
SSPC: The Society for Protective Coatings recently announced the revision of the SSPC-SP 13/NACE No. 6 “Surface Preparation of Concrete” standard, which has been updated with more relevant companion standards and information from technical papers.
SSPC-SP 13/NACE No. 6 was first published in 2003.
In the recent update, Table 1, Classes of Surface Preparation per ICRI 310.2, was added, providing classifications for surface preparation methods to make them easier to identify. Definitions were also updated.
Minimum acceptance criteria were also boosted from suggested to mandatory, though they can be superseded by procurement documents or coating manufacturer requirements. Section 6: Table 2, Minimum Acceptance Criteria for Concrete Surfaces Before Coatings Are Applied, also received a boost, moving from the non-mandatory appendix in the old version into the standard proper.
The section on flame cleaning (previously Section 4.3) was removed, and the appendices were reorganized, now including information on surface preparation methods, concrete surface tensile strength and coating adhesion testing.
The standard costs $25, and is available for purchase via the SSPC Marketplace or the SSPC app.
