Great Stuff 99112876 Smart Dispenser Multipurpose Black, 12 Oz.

Works great! Just wear gloves, if you get this on you, it takes a week to wear off , scrubbing and chemicals don’t work

Have admit that I was going for the pond foam but it was going to take too long To deliver. So I got this one and boy is it better and works better then the pond foam

I’ve spent my life as a building superintendent, have tried many different products, this one is best for rv’s because of the weather penetration as you move down the road. Just follow directions and the few tips I share. It’s perfect for Rv gaps around underbelly and wiring holes. I cleaned all surfaces with 91% rubbing alcohol to prep surfaces and help it adhere. The one review that said it didn’t stick, he probably didn’t prep surfaces or shake it well. I also heated up the can by soaking it in hot water before applying. It expands more than one inch, more like 2” (maybe because I heated it up?) Says it is for exterior applications, once it cures you can trim excess if you like. I was impressed how far it covered. Went all the way around my 40ft 5th wheel. Just a warning, wear gloves, this stuff is sticky and doesn’t come of skin or clothes. I bought another one to seal all piping as it penetrates through the floor and to go into basement to seal everything else up in there. Really love this stuff, it’s a great product and I highly recommend it.

I bought this to seal gaps on the outside of my house. My foundation is painted dark grey, so the black matches better than the typical yellow sealer. I have noticed some fading from the sun, but it doesn’t affect the quality. Works pretty well for my old house.

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.

I like the way it looks. It filled the gaps in and is easy to work with.

Had many small projects that took 7 months to use up the can. It never clogged and I was able to use the entire can.

I thought it would fill gaps. It doesn’t. It is strong and blends well with the dark background.
