SSPC Issues Revised PA 7
SSPC: The Society for Protective Coatings recently announced the revision of standard SSPC-PA 7, Applying Thin Film Coatings to Concrete.
The 2017 revision clarifies that “thin film” refers to coatings with specified dry film thicknesses under 20 mils, and notes the requirements that the contractor shall verify to ensure the surface preparation of the substrate meets contract requirements prior to coating application.
Prior to placement, coatings must be cured in alignment with manufacturer recommendations, and that any touchup most be done in accordance with either project requirements or the originally specified coating system.
The list of referenced standards and the definitions has also been updated, notes SSPC.
SSPC-PA 7 is intended to be used by both owners and specifiers to supplement product application requirements.
The scope is limited to proper application practices for most types of commonly used coatings.
The newly revised PA 7 can be purchased through the SSPC Marketplace or the SSPC app.
