great stuff

We all know how to reuse our cans of great stuff in the span of a day or two, but how long is the shelf life on them after opening? Let's say after you create your background you still have half a can left and want to save it for your next project; how long could you store it for before it...

Would great stuff foam background get destroyed if one small spot that had been carved didn't get covered with silicone and substrate ?

I am having a bit of trouble with some sections of great stuff in my build. The surface of the spot is really rough and pitted, to where it will be quite difficult to get an even or complete coat of drylock onto. I have tried carving and respraying but due to where the egg crate framework is...

After having spent a good 10 hours, at least, on this tank so far the greatstuff seems to be peeling. What makes it worse is that it isn't peeling along an edge but in an inaccessible corner. It has now been a week since background was completed (in case timeline is helpful). I am hoping someone...

Hi everyone! First post. I have been searching forums for days and can’t find a solid answer. I am constructing a paludarium and wanted to do an egg crate silicone backing to hold up a larger piece of drift wood and other things. I covered the back with black silicone and waited for it to cure...

So, having read multiple accounts of people's great stuff failing to adhere to aquarium glass, I took the advice advanced by NEHerp and first applied a layer of silicone to the interior glass. This was cured for several days before I took the next step and added the Great Stuff. In both tanks...

Hello Dendroboard! I'm Spdybee and this is my first post here. Been lurking for a couple of years now, reading and learning. Since I've started my first real viv I thought I would document the process to share my experiences like so many of you have. First a little history. I say...

So I'm planning on building a vivarium for my group of 4 marbled newts. Since they are still young and newts do enjoy a lot of time on land i figured a divided 36"18"18" exo terra would be perfect. The tank will just be mostly moss, ferns, and cork bark branches. Excited to use my new Finnex...

For those who have gone with using great stuff to make their backgrounds do you find that the foam sticks to the glass or not? I've made a few by applying silicone on the glass first so the GS has something to grip onto. Just wondering if there is another way so the tank/glass isn't completely...

I'm in the process of my first build. I used way too much Great Stuff, but it turned out okay. I let it sit overnight and started cutting holes into the great stuff for plants and the inside is still gooey. My question is, should i coat the inside of the holes with silicone? With Great Stuff...

Hello, I'm thinking of starting a new project and need some help! I always used coco panels and cork panel for backgrounds, but I wanted a GS background for my 120x40x40cm tank. I have 4 pieces of mopani wood that I would love to use on the background, but I'm afraid that they are a little...

I have been using a mix of Styrofoam and Great Stuff to create some features in my viv which have since been coated in layers of cement. In one of my pieces the Great Stuff didn't get enough oxygen to do what it should have done and is extremely porous and has some decent holes the width of a...

So I have an old viv I had going a few years back but was 'out of commission' due to moving. It is now dried up with no plants in it. Here is a pic of when it was up and going. Now I plan on fixing a few things up. There are a several key updates I want to get done and hopefully all of you...

What sort of great stuff should I use for a background as there are loads of types! Thanks

I have been searching the threads for a while gathering ideas on how to rebuild my 40 gallon Oceanic Hex once again. I finally decided on making a water feature and some trees with sheet foam and Drylock. My main motivation, besides getting lost in a fun project, is to make a low maintenance...

I would like to build a paludarium without a false bottom and am researching various ways to build up the terrestrial portion. I very much admire the tank shown here: Paludarium. He uses layers of gravel, stones, expanded clay bricks, clay balls and then soil. I can't find expanded clay bricks...

I have done 1 Vivarium in the past and now that I am starting my second I thought I would track the progress and get any input or ideas from anyone that viewed this. With this only being my second full vivarium I thought maybe I could learn something and maybe it can give other people ideas. I...

I am doing a background of GS and then going the silicon + (Something) route of covering it. I was going to do straight eco-earth but have read a bunch of really good things about tree fern. Any opinions on what would make the best back. I want something that plants will grip to easily! Here...

My tank is coming together nicely. 32x20x20 so ~55 gal tank. Im doing a greatstuff foam backround on it and needed some assistance. what is the easiest way to put the backround in. Would i be better off doing the entire thing inside the tank right on the acrylic, or would i be able to do it...

Hello, I just recieved a big order of plants today from Black Jungle Terrarium Supplies and am looking for different ways to plant them in the background. I was wondering if it would be ok to just cut a hole in the GS and plant it right in there. The holes i made when i constructed the...
