(3) Permanent repairs. A durable repair will use the same MB material as in the original
membrane torched, mopped, or adhered as appropriate for that material to a properly prepared
substrate.
d. Repair Work by User. The occupants should keep compatible mastic, trowels and reinforcing
on site for emergency repairs and patching. Torching of MB requires storage of propane fuel (which is
a fire hazard), appropriate tools, membrane material, fire extinguishers, and trained technicians.
Torching is quick and very effective when done properly. Training may be provided by MRCA certified
trainers.
e. Checklists. Use RIEI or other industry checklists to aid in conducting visual inspections.
Perimeters, seams, tee-joints and flashings are high priority items, as are roof drains.
