H386 2003 Sealant around Skylights

[Adamt24]

hi
One of my skylights is leaking - the black sealant is lifting a bit- is this a job anyone has done ? If so how and what sealant?

Thanks

I have used Life Seal. Comes in black or white. Tape both edges to prevent excess spreading and to get a nice finished edge.

thanks - did you cut out the original sealant?

 

[BayMan]

I did not because there was a healthy trough to put in the new caulk.

I had a leak in mine. I choose to match the original sealant as much as possible so I would be assured that the new sealant would adhere to the original sealant. They original sealant was Dow 795 and I resealed mine with Dow 995 (better properties). I removed the trim on the inside window and added new sealant. Many places didn't have the sealant up against the fiberglass and the window, so I filled those voids. On the topsides, I taped off both sides and applied additional sealant on top of existing after cleaning it. No leaks since the application and it has withstood 50 mph winds with driven rain. Very satisfied. FYI... two person job with plenty of paper towels, cloth rags to clean-up as you go. The finished product looks like new.
