Quick Question on Eternabond and skylight

[buzzards27]

Anyone know what the skylight is made of, PVC, silicon based, something else? Is it compatible with eternabond tape?

I am in the process of stripping down the cracked up/globbed up caulk around my skylight. I am wondering what type of material the skylight over the shower is made from. To the touch it has that feel of a silicon based material so I am wondering if I can use the eternabond tape instead of caulk...

I did a tiny test patch on a spot where I removed the caulk already and it wasn't dirty and weathered. It held pretty good but because of how small the piece was I'm unsure of the bond's integrity.

You'll see that a lot of folks have gone the Eternabond route, with success. I put it around my skylight last year and haven't had any problems so far. One thing you really need to do is work it on really good. I had some edges of the tape that didn't seem to hold, but I rolled and rolled it and now there is a good tight seal.

yep, read all the threads, having a clean substrate seems to be the most important factor. I am "planing" down the caulk and removing the dirty that way. I have a nice bright white surface where ever I'm leaving any caulk.

I just didn't see anyone question what the skylight was made of, seeing the tape and silicon don't mix....

The weather today was too good to pass up so I went ahead and applied the ethernabond tape to the skylite and I'll hope for the best. Hope I'm wrong, but the darn thing feels so "waxy" I still think it may be silicon based....

I've used it over my previous stuff last year and all is well.
If you can remove any dirt build up will be helpful in the long run.

thank, all is well with my install, so far. I did buy the cleaner. Buzz
