NOTE TO SPECIFIER: Require that backup concrete be free of fins, protrusions and large holes
 
B.
Section 04 20 00 - Unit Masonry.
 
NOTE TO SPECIFIER: When concrete masonry unit (CMU) block walls are to receive Air & Vapor Barrier materials it is critical to address surface preparation issues in this section. Due to the method of installation of the CMU, generally from the inside out, the most critical surfaces to receive the Air & Vapor Barrier materials are neglected and not tooled properly. It is strongly suggested to cut and paste text located in PART 3 - EXECUTION, of Section 07 27 13 into Section 04 20 00 - Unit Masonry. The masonry trade must be made aware that this is a critical element for the self-adhering Air & Vapor Barrier material. The performance of the Air & Vapor Barrier material is directly related to the substrate over which it will be applied.
