Questions & Answers


How do you clean the straw

Asked by Nina June 6, 2021

Blow it out with a can of compressed air.

Can i use this for a new window

Asked by Vic May 31, 2021

Yes. It does not matter if the wall or the window is new or old. It will fill up holes or cracks. If you want it to look nicer after you apply it, then make sure you wipe away the excess as soon as you apply. It dries quickly and it is very sticky, so I suggest you use a old rag or rags.

Does this come in different colors or only the ugly yellow color

Asked by Rame May 5, 2021

Not that I am aware of.

Ok for kitchen cupboard? Mouse got in through a quarter sized man made hole.Cleaned/set trap. Has not come back in 2 wks

Asked by Nick April 27, 2021

I would keep it way from dishes. A mouse will chew right through this stuff.

Can I use it to seal underneath a tub.

Asked by Lj April 24, 2021

I would recommend a silicone sealant; it would be a more effective watertight sealant.

How can I remove excess foam

Asked by Anita March 30, 2021

Generally I use a utility knife or razor knife to cut foam flat across top and side making it even with walls or corners then sand smooth primer n paint.

is this fire rated?

Asked by ldv18 March 25, 2021

Dear LDV18: Good question, but all versions of Great Stuff are VERY flammable -- even when they have "Fire Block" on the label. All versions of Great Stuff -- and similar canned spray foam from 3M -- will ignite at just 240 degrees F. This is significantly lower than the ignition temp for paper or wood. So Great Stuff and similar products will ignite FIRST. Canned foam is banned in commercial construction for "fire stopping" -- e.g. sealing holes in framing around pipes and electric lines. It is used in residential construction only due to a gap in the code. Your local inspector can 'approve' your use of canned foam. Informed inspectors can also fail your inspection, forcing you to spend lots of time digging foam out of holes, then filling the holes with real fire resistant sealant. On a recent project the inspector walked through, smiled and said, "You avoided a costly rework job. Many contractors still use that orange foam." To fire seal, e.g. around penetraions in framing for electric lines and plumbing, use true fire resistant caulk, e.g. 3M Red Fire Barrier CP 25WB Plus Sealant, Model #CP25WB+10, Home Depot Internet #100166701, UPC Code #051115116384. For larger gaps, pack them with rock wool then cover the rock wool with 3M sealant. I hope this is helpful. Mark

Asked by James March 1, 2021

Yes it can be reused, but you need to clean the straw out immediately after you are done using with a long piece of thin wire. It won’t get it all out, but it will allow you to use it again.

Can I use Great Stuff behind my electric range where mice find a way into our kitchen?

Asked by Mark February 23, 2021

I would say that it would help. It is a very light foam. I’m not a mouse expert, but they could theoretically chew through it. It would be worth a try in my estimation.

We are sorry to hear that our products did not work according to your expectations. Best if Used By/Expiration date information can be found on the bottom of the can. As with all items sold through retailers, product should be returned to the place of purchase for exchange or refund.
Nozzle impossible to control; buy the Pro gun instead
I'm not a contractor so I bought Great Stuff in this DIY container to seal up cracks in my garage walls before insulating. As others have said, the nozzle is extremely difficult to use; the foam either barely comes out or it splatters all over the place. I was glad I was wearing a tyvek suit. Plus, as I know from past use, if you stop partway through a project and don't use the whole can right away, the nozzle seals up and the can is useless from then on. So I bit the bullet and went back to Home Depot and got the contractor-grade Pro Gun, and containers of sealant and cleaner. What a world of difference!!! The flow from the gun is finely adjustable and easy to set up for exactly the amount you want. Plus, you can leave the gun on the can and use it again and again, for up to a month. Unless you're on a very tight budget or are much better at dealing with frustration than I am, skip a few lattes and put the money toward buying the Pro gun; the job will be much easier and much more enjoyable.

Hello - Thank you for sharing your concerns with us regarding Great Stuff™ Insulating Foam Sealant products. We apologize for any inconvenience you may have encountered.

Works well
The foam sealant works great and closing up the gaps from running copper pipes through the wall in my garage. I used this same brand but specifically for windows and door jambs recently and it is fairly easy to use. Can be a dirty job if you use too much foam. The foam continues to come out for about 2 seconds after you release the trigger. So it's best to release early before you want to end.

It won't stop, it keeps getting out!
I sealed a couple of cracks and holes in my basement and everything worked great until I decided to stop and keep it for the next project. It just never stopped, it's in my garage now and it keeps coming out, I see a big blob of gooey stuff already and I am a bit worried that It will fill up my whole garage and I won't be able to open the door in the morning.

Hi, Tim - Thank you for sharing your concerns with us regarding Great Stuff™ Gaps & Cracks Insulating Foam Sealant. We apologize for any inconvenience you may have encountered with this product. Once the foam has cured, it cannot be removed with solvents and the only option is mechanical removal. On hard, smooth, or polished surfaces this may be accomplished very carefully with a single-edged razor blade. If you can see the bottom of the can and it is still within shelf life, you can return it to the point of purchase for a refund or exchange. Great Stuff™ Insulating Foam Sealant products are not designed for reuse as one-component foam cans will seal themselves shut if left for two hours or more after the initial spray. We have developed a new dispenser called the Great Stuff™ Smart Dispenser™ that does allow for reuse up to 30 days after the can is first used.

You are using spray foam wrong
Take the straw off and you have a full blast substitute for a spray foam kit. 40 cans completely air sealed my attic and cost half of what the smallest froth pack costs.

This product is an air sealant only and is not designed to provide any type of insulation, only block air movement from small gaps and cracks. The Froth-Pak™ Foam Insulation kit is formulated to provide insulation in your home. We do not recommend the use of Great Stuff™ Insulating Foam Sealant products in the application you have described here.

Nightmare to use - coaider Loctite
For context Im a diy’er with no prior experience with spray foam. We moved into an older house which had gaps and holes internal to the house that were letting in pests and mice. So I turned to spray foam as the solution for larger gaps where caulking wouldn’t work. I started by buying 3 cans of this stuff. Let me tell you, it’s a nightmare to work with. Why? 1. The product comes out so quickly it’s difficult to control. You end up spraying way too much then have to spend a lot of time cutting extra. 2. Because of #1 is gets all over the place. Your hands, floors, clothes...really anything around. 3. The screw on spray tube is defective. With all three cans, the product began leaking out of the underneath of that screw on spray tube. 4. Some cans barely worked at all. One I got one spray out of before it jammed up and I threw it away. Overall this product is terrible. I gave up on GreatStuff and went and got a few cans of Loctite Tite Foam. Solved every problem above. Easier to control the spray, easier to clean up, and no leaks out of any of the cans. From my experience, vastly superior product. Having said that, in fairness, i have no results yet on which is more durable. A few tips if you’re like me and want to use this stuff: * use caulking wherever possible before turning to this * It expands, a lot. You can always add more so use lightly. * Spray foam is flammable. VERY. If I had known this up front I would have gone a different route all together. * Make sure you have plenty of disposable gloves. * Keep lots of paper towel around and a few wet rags to clean up. You’ll definitely want to wipe up overspray. * Get some acetone if you’re going to want the finished product to look nice. I didn’t care about that for where I put it so I didn’t bother. Good luck.

Hi, OCDad - Thanks for sharing your concerns with us regarding Great Stuff™ Gaps & Cracks Insulating Foam Sealant products. We are sorry for any inconvenience you may have experienced. As recommended on the label, please use protection to avoid contact with skin and eyes, so please wear gloves and goggles. Uncured foam can be removed with acetone, but cured foam requires mechanical removal from surfaces. It is not harmful if you get it on your skin, but it will take time and effort to remove it. Also stated on the label, cured foam is combustible and may present a fire hazard if exposed to flame or temperatures above 240F (116°C). We have developed a new dispenser called the Great Stuff™ Smart Dispenser™ that allows for greater control and ease of use. As our retailers sell their existing inventory, they are restocking with the Smart Dispenser™ products which will be available wherever Great Stuff™ products are sold.

I used this to fill in the gaps around a wall-mount AC unit, so that I could tile around it, instead of using regular moulding. Worked out great.

This stuff is horrible
I try to seal around items in my attic and if you just slightly pull the trigger it flows out like a dam broke. It didn't stick so once this crazy amount of foam dried it just brushed away so not sealing any air leaks in the attic.

Response from GREAT STUFF & DuPontFeb 24, 2020
Hi Pyro5263,we apologize the product's performance did not meet your expectations. Great Stuff™ Insulating Foam Sealant products will chemically bond to just about all surfaces in a matter of minutes & should not just brush away. Please give us a call at 866-583-2583, so we can discuss what may have happened.

I love Great Stuff foam and I use it for a lot of insulating projects. That 'Quick Stop Straw' though has to go! It keeps getting bumped closed when sticking the straw into whatever crevice you are insulating. Then you have to snap it back into the open position. That's bad enough, but in the meantime pressure has built up and when you open it, it splats uncontrollably everywhere. Ughhhh! By the end of the can it is majorly bunged up and won't move so I had to cut the end off to finish what I was doing. Foam is great, straw is a total fail.
