Great Stuff 99112849 Smart Dispenser Pond & Stone, 12 oz, Black

I bought this to seal a septic tank riser to my septic tank and it was easy to use and works well for my application and need. There was plenty of it to use for the job that I was doing with some left over to do a few other things. It wasn't messy at all since they've made it reusable. It sealed everything nicely. It didn't have an odor at all. As for the looks it won't matter in my application. It served its purpose for what it was intended for. It did fill the gaps nicely for my purposes. I couldn't find this in my home improvement store so I bought it along with the riser at the same time. Glad that whomever made this stuff reusable and easier to use made it for homeowners to use later if not all used up at one time within a 30 day period.

I was hesitant the spray patterns would make it look weird so I used a glove to mess it up so it was even while spraying. Came out strong at first and then fizzled out and was kinda hard to spray. Can get messy if you aren't careful. I used one and a half cans for the back of my 20gal tank. Pretty easy to do if you are patient- I let mine cure for a week because snakes are sensitive to glasses and fumes. Afterwards I took a sharp little knife and carved some peices in the back so they looked a little more rock like. Looks amazing ( I'm getting a charcoal pool soon so it will match the back wall haha). Super happy with the turn out!

It's great stuff. Finding the color black isn't always easy as I travel around the country in an RV, so Amazon is a good place to find it consistently as well as being a bit cheaper.

I recently used the GREAT STUFF Pond & Stone foam on a water feature I’m building, and I’m genuinely impressed. The black foam blends in seamlessly with the stones, giving a clean and natural look—not the usual bright yellow or cream that sticks out like a sore thumb. What I loved: • Smart Dispenser™ is a game-changer: No more drips or mess. Once I stopped squeezing, the foam stopped instantly. Also, you can reuse the can for up to 30 days after the first use—huge plus! • Works great in wet environments: Perfect for my pond setup—safe for fish and plants, and bonds stones together without needing mortar Easy to apply: It disperses foam evenly and slowly, giving me precise control when filling gaps between rocks This product is a top pick for pond builders, landscapers, and anyone working with wet environments and stone features. The no-drip Smart Dispenser, black color, and water-ready formulation make it truly stand out. Just handle with care, keep your nozzle clean, and be ready for some stickiness. Overall—worth every penny for a neat, reliable outdoor sealant.

Used on outdoor water fountain around base of one of the bowls where it connects to the spacer. Messy so I'd practice a bit on a piece of cardboard. Make sure nozzle it very tight. Worked very well sealing and stabilizing the bowl. Wear gloves!

this saved us money

Love this product. We use it to build bioactive Vivariums for all our reptiles and amphibians. It dries quickly, expands well, and holds better than other brands we have tried.

I wanted to create a backdrop for my ball python's 4x2x2 terrarium. This product is good but the issue with trying to use something like this to cover that much area is that the "pond and stone" version of it is formulated to not expand very much because of its use for between ponds and stones lol. I found this to be an issue because I needed to cover a lot of area and one can of this doesn't go very far at all. It's also 2 if not 3 times more expensive than the regular red can. The nice thing about using this is that the foam is black which blends in well for a background. So if you have smaller area to cover, this can work well. The Great Stuff in the red can (Gaps and Cracks) is much better to work with because since it expands further, the foam goes further in your project and it makes it waaay easier to carve to your liking if you so choose to do so. Then you could cover it with black aquarium silicone. It is really water resistant and holds up to humidity well. Make sure you wear gloves. The foam does have a slight smell but it goes away pretty quickly and cures in a day. I would like to say that after completing my ball python's terrarium, I would highly recommend against using the foam/silicone method as it is tedious and kind of outdated. It took forever to carve the foam and a month for the silicone to no longer off-gas after covering the foam. I'd recommend using the cork board method instead and just using the foam to attack branches, etc.

Muy rendidor, fácil de aplicar

So nice when you find a product that does exactly as advertised. I’m beginner/home DIY pond builder and this made my rock feature wall stay exactly as I pictured.

Super pour modeler un terrarium. Mon fond de terrarium humide et effectué avec ce produit et même après un ans, il tient toujours aussi bien. À utiliser la même journée puisque le restant finis par sécher dans la paille et très difficile de le refaire fonctionner.

Stick juice is extra sticky

It formed perfect with my jobs
