5.6 Allowable Substrates:
5.6.1 Direct-Bond to Deck:
Citadel Plus, Boral TileSeal 50HT, Boral TileSealHT, Boral MetalSealHT or GatorSeal:
➢ Plywood (unprimed or primed with ASTM D41 primer).
Boral TileSealHT or Boral MetalSealHT:

➢ ASTM D226, Type II felt; Citadel Plus.
For installations under mechanically attached prepared roof coverings, base layer shall be attached per minimum
codified requirements. For installations under adhesive-set tile systems, base layer shall be attached per minimum
requirements of FRSA/TRI April 2012 (04-12), Appendix A, Table 1, or as listed in Section 5.6.4 herein, or as tested
in accordance with FBC 1504.3.1.

that are not addressed in FRSA/TRI April 2012 (04-12) and are used in adhesive-set tile applications. Maximum
Design Pressure is the result of testing for wind load resistance based on allowable wind loads, and reflects the
ultimate passing pressure divided by 2 (the 2 to 1 margin of safety per FBC 1504.9 has already been applied). Refer
to FRSA/TRI April 2012 (04-12), Appendix A, Table 1A or FBC 1609 for determination of design wind loads
