NOTE: Do not install when rain is expected before the sealant reaches initial cure. Substrates must be
absolutely dry or bubbling may result. **All Flex Roof Systems require pitch pans to be made of
Flexclad coated metal.
METHOD OF APPLICATION
1) Install Flexclad Pitch Pan around the penetrating object according to Flex’s current specifications and
details.
2) Fill bottom of pitch pans with concrete or other suitable fillers. Do not use other caulks or sand as a
bottom bed in a pitch pan. Flow the sealant into the pitch pan and taper the sealant outward to provide
positive drainage. The maximum depth should be 3/8” deep.
CURING TIMES
Cure of Flex Pourable Sealer will vary with temperature and humidity. Under normal conditions (75° F

cure in approximately one week.
CLEAN UP
Immediately after use and before sealant has cured, clean equipment or material with an approved,
suitable cleaner or solvent.
