Revision context

Document record

The 11-page application guideline covers the Max-Ply full-fabric membrane system installed over modified bitumen roof surfaces. The cover shows 10/06/25, and the page footers repeat that revision date.

Part 1 states the purpose of the guideline, which outlines materials, methods and conditions for applying the system, and it requires the approved applicator. Part 2 lists the system components. Among the coatings are Silicone 410 with 318% elongation, High-Solids Silicone 412, Aliphatic Urethane 510-CA, Aromatic Urethane 508 and 520, and the Acrylic 211 family. The accessories are spunbound polyester fabric, Acrylic Bonding Primer 905 and ECOCLEARNER 925.

Part 3 begins on the third page of the file with installation requirements for the substrate and primer application. Part 1 also says the contractor should outline penetration, drain and flashing work separately before the work commences, following good trade practices.
