Red Devil 091512 Foam & Fill Fire Block Expanding Polyurethane Foam Sealant, 12 oz, Orange, 12 Pack

My travel trailer shower had an unsupported floor that moved when I used it. This is common to many plastic insert showers.I wanted a neat way to support the floor without raising any fire danger since wires and pipes run under the shower and are subject to vibration when I drive.Red Devil Foam and Fill is perfect for this task. I filled the pipe entrances under the trailer, foamed around the wheel wells to stop the annoying cold draft on my feet, and foamed the underside of the shower.Much easier to clean up - but still not easy. After all, it is a sealing foam so it seals everything it touches. All in all, cleanup is possible and the result is a much less drafty trailer with a solid floor in the shower.

While going through a house sale closing, the buyer's home inspector gigged me for not having fire retardant insulation around the floor openings where my air conditioning ductwork was installed. So, I purchased two cans of this foam and fill and filled in all the gaps around the ductwork and that was that. Second time around it passed the inspection and I sold the house. So this fire retardant works and I learned a BIG lesson. If you are selling a home in today's market, download a copy of a sample home inspection report and go around your house and fix problem areas BEFORE they hold up your closing. ESPECIALLY, get a termite inspection BEFORE putting your house on the market. My house was clean of insects but if you get gigged for termites you will loose a buyer and you will have to disclose previous termite damage on your home disclosure....forever. But if you fix it beforehand, if you fix all your problems before it is listed, and you treat any insect problems, and repair any insect damaged wood (because the inspectors will find it), you will avoid HUGE problems. Also, if you have a well, get the water tested BEFORE putting it on the market. Home inspectors and water tests are much more effective than they were 20 years ago.

Ok, i lied a little, but needed you to read this tip. Place the can in the sink or bucket and fill with hot water from the tap. After 20 min, give it a few shakes, hold upside down and you will get every drop out of the can.I do this for all foam products including the foundation fix, great stuff, etc.Hope this helps, i wrote this because some people couldnt get all of the product out of the can.

This would work well as a fireblock/insulator filling walls or cinderblock etc. I needed it to fill something that had electrical components and hot metal tubing. It worked well for my purpose. Only thing in the description that I disagree with is that it's "sandable". It doesn't get hard enough to really be sanded (it remains a bit spongy) and also has fairly big holes and voids in it. So I wouldn't describe this as a sandable foam. Also it is insanely sticky and will stain anything it gets on red/orange. It probably expands 3x it's original size. Also, this is a single use product. After the first use, the nozzle thing gets clogged up and the foam just leaks out where it connects to the can at that point. So this is basically for a single use and would work best just sticking the nozzle through a hole in a wall or something.

This was hard to control. Even got on my hair. If gets on your hair, it feels like super glue, but once it dries, it becomes easy to remove. This foam doesn't expand much. It is best for small spots by the radiator wall to prevent mouse openings. Other than that, it is really messy to use and I would prefer not using it all.

Good product but be careful of getting it on your clothes

Had the opening I needed to seal and fireproof been made of human skin, this would've worked wonderfully. Alas, it was not. It was, instead, constructed of your everyday, standard, run-of-the-mill building equipment (wood and aluminum). When spraying out, it refused to stick to anything, thus falling back onto me and my human skin, to where it decided it was now identifying as superglue, and no as a fireproofing hole sealer. I'm too tall to be an oompa loompa, therefore I fear my transition into Donald Trump has begun.

Just wear gloves

Terrible to work with. It clumps in the straw and nothing else it drips and drops all over AND it doesnt expand much so the foam doesnt go far at all. I had it all over by the time I was done. And the worst part is its orange...... So it really stands out if you dont plan on covering it up. I should have just thrown my money down the drain. Oh and once it was dry I could still feel a draft and I could smell my neighbors cigarette smoke. I used duct tape instead. :/

Does the trick, but takes some finagling - it's more runny than it should be, and it makes a mess of anything it drips on. I got it to work, but wasn't expecting to have to put so much effort into making it stay where you want it to, before it hardens.

I was disappointed in how little coverage it gave, and how little it expanded, not to mention the hideous colour. I don't recommend this product.

I purchased it to seal the hood access outlet, and it immediately solved my problem. But it was my first time using it, and it made a mess all over the place. The pipe will most likely become clogged the second time I use it.

works well! volume wasn't too much to use. but over all good!
