Expert Verdict Reviewed by the SuperArbor Pro Desk

Self-adhered SBS mid-ply sheets simplify low-slope multi-ply work by removing torch and mop from intermediate plies. Verify deck condition and primer requirements before adhering, and stage rolls so the adhesive backing stays dry and clean. Follow the Flintlastic SA system layout for ply and lap sequences.

Handle large membrane rolls with care on rooftops and follow manufacturer instructions and safety practices during installation.
