Great Stuff 99112876 Smart Dispenser Multipurpose Black, 12 Oz.

Mice were getting into the house occasionally. Used this stuff to fill crevices in the concrete and bricks along the foundation. Blends in nicely. No more mice so far. Careful applying it, read the directions and wear latex gloves. Use less than you think you need; it expands.

Who doesn't love Great Stuff? And now that it's available in a "smart dispenser," do you really have any excuse to not buy it? This worked great to seal up some gaps in a 1963 Airstream I am renovating, and the black color just looks way more classy than the regular foam does. For when you want to brag about the plumbing in your RV to the neighbors.

First time using this product to replicate stone cave for my paludarium. Once fully hardened, foam is very sturdy & hard to cut & remove if you change your mind on the set up. Feels like styrofoam. Smooth shiny black color. Once cut into form, appears charcoal in color & matted. 1 can dries in about 30 minutes or so. Better to wait an hour & cut to desired form, foam would be easier to work with VS days later when fully cured. 1 can wasn't enough to create a thick wall, so I ordered 4 more cans (from Home Depot--needed it ASAP). Smell wasn't even that strong. (Project finished outside) Tilt nozzle in the direction you want output or else foam will not come out consistently thick to cover surface, instead will be frothy like soap. USE ENTIRE CAN OR IT WILL HARDEN & CLOG NOZZLE Wish that a can would expand a lot more than it did, expansion was a bit less than I anticipated. (Maybe it was my first time & didn't spray properly) For my project, I preferred the cream color because it was easier to work with than this color which had weaker expansion & too glossy. Overall, I highly recommend using this for a project like mine VS using real rocks because your tank will be lighter in weight & overall easier to work with than gluing rocks.

Worked as expected. Good stuff indeed. For those new to this product, do chexk out a video to see how this product works as if you dont know what you are doing can end up making a mess and/or overusing. Make sure you get your stuffing/sealing job(s) done in a day or 2 as the foam left in the dispensing tube can fully dry and making it unusable.

Bought this for under my RV. Comes out dark gray/black so it blends with the underbelly. It is easy to use but very sticky so wear gloves when applying. Cost the same as similar product in a big box store.

This is such a good brand and it’s well known for a reason! Super easy to use, works perfectly and has sooo many applications. Great stuff is a great brand!

This stuff really is great. It feels huge gaps and it lasts a long time and it's waterproof. Just be careful you don't get it on your hands. Wear gloves or you'll be sorry

I bought 3 cans. Used one and worked pretty good although it doesn’t stay in place so I ruined the hoodie I was wearing. The second can only did half of what the first can did before stopping and wouldn’t spray anymore but I could tell there was more in the can. The third can did ok but I haven’t used but half of it so I don’t know if it’ll resume spraying or not when I need it. It doesn’t clean up well so try to keep it where you want it.
