I used Black Jack roofing cement to fill a small gap where a piece of flashing was missing. I put a pretty good size bead/glob to ensure I filled in the small gap and the gap between the roof and the bottom piece of hardiplank. So, you can imagine how thick it is. It has be a good day and a half since I have done it and it's just as wet as when it came out of the tube. Is this normal? And, if it stays like will the force of a heavy rain mess the bead up? Thanks for any input!
It's supposed to stay liquid/flexible and self sealing. It;s not designed for large gaps the way you used it. If you're stuck for a patch, try a few layers of aluminum foil coated and fixed in place with that cement to close the gap. Not as good as replacing the flashing, but better than what you've got.
No, no, no.....don't laminate pieces of aluminum foil with plastic fibered cement as suggested. Foolish suggestion. Your glob will eventually develop a skin and slowly harden. Being summertime, it will take awhile. Keep an eye on it to make sure it doesn't drop through the area your attempting to seal. When you decide to re-work the area purchase roll flashing aluminum.....you can cut it to any size or configuration desired and then the Black Jack.
