Great Stuff Question (Again...)

[M1A1]

Firstly, I am new to the site. I have been lurking for some time and finally felt the need to introduce myself and pose a question.

I have read almost all the posts on Great Stuff, but did not find one which covered my question. If I have skipped or forgotten it, please let me know and slap me around a bit. Anyways, my question: is it problematic when applying GS to tank backs (30G tall)? I imagine that it would be difficult covering the area and not getting junk on the side panel glass. Is excess easily removed via razor or some other means?

I have considered having a plate of glass cut to size, applied with GS, and siliconed to the tank back, but am afraid of weight issues. This being as my plan is to inset flat river rocks and silicone Eco Earth in between, undoubtedly accruing a good amount of weight.

Thank you in advance for any and all help!

PS: This will be my first vivarium, constructed for a Crested Gecko.

I'm in the process of using this stuff to construct as well, my plan and also a suggestion I read is to cover the entire back of the tank in 100% black silicone and ALSO cover about 1/3 to 1/2 of the side panels. THis way, after applying the great stuff you can use a razor blade to scrape away the extra silicone with extra great stuff attached to it, and makes everything a lot nicer and cleaner looking.

I haven't been on in awhile, in fact, long enough for my account to go away and had to re-apply.
I had to respond to your questions about great stuff..
be carefull covering the whole surface or panel inside a tank, it will continue to expand overnight and has been known to shatter the glass.
It will stick to glass, and can be cut back with a razor or even a serrated knife once it is set.
Id advise only covering up to 2/3 of a panel and wait until it is set before adding more the next day in layers. if you take the spray tube off when you are done, and clear it with a wire or something, you can re-attach it later and use it again... so dont feel like you have to use the whole thing in one shot.
I have used silicone on the glass prior to using it and that works too, if you spray it on a vertical surface, it will slide down so lay the tank down on the side you are spraying down.
good luck
