Just installed a dryer vent pipe hood through outside wall, which is stucco.
Caulk was put around the aluminum hood piece that was on the stucco. I didn't do this myself, so unfortunately I can't give exact details of caulk except that it was supposed to go on white and then turn clear after curing and I assume silicone.
The dryer was used less than an hour after this. I noticed that the caulk on top (which had a good gap between it and stucco) had sorta "swellled" up so it is now protruding upwards quite a bit (although still meeting wall and plate). In addition, it stayed white and is rubbery to the touch, not hard. The sides mostly turned clear, but have a sticky feel to them. I assume the intense heating of the aluminum screwed up the caulk so it didn't cure correctly.
What can be done? The problem is that if you try and take off this caulk it will damage the stucco (unless there is a chemical way to do it). If the excess on top (which is the part that is cosmetically unappealing--kinda like someone took a tube of toothpaste and squeezed it out--is cut down a bit (before getting to stucco), can new caulk be put on top of the remaining bad caulk? Will caulk stick to caulk anyway?
Any ideas? I am lost because I have a feeling that the stucco is going to be damaged and the cure worse than the problem.
