use a piece of wax paper between door frames and doors,the exspansion of the product will hold it in place and will pull out when it comes time to remove it.

whar is the reaction tmperature when curing?

thinking about using to make a mold.
Asked by: Anonymous
There is no substantial change in temperature during curing. I think it may actually be a mild endothermic reaction. I would ask the manufacturer if you're using this in some application where such a question is relevant.

16 oz. Window and Door Insulating Foam Sealant is rated 3.7 out of 5 by 13.
Rated 1 out of 5 by from Poor Delivery System Can only use one time. Due to the delivery system design it clogs no matter what you try to do. - Leave product in tube and cut for next use = does not work next time - Take off clear handle/hose and spray clean with brake cleaner and shoot compressed air to really clean out = does not work next time Ends up being a huge waste of money unless you intend to utilize the entire product right when it is first used. The company needs to talk with the can vendor or if Dow is also making the can they need to re-design! Will find alternative products to use.

Rated 5 out of 5 by from Excellent product for insulating most anything. I am restoring a military M-1028 1986 4x4 pick up truck. I used FatMat to insulate the entire cab, floor, firewall and doors. The roof is a double shell with a 1.5" gap. I drilled 6 evenly spaced holes 4/32" to accomadate the great stuff filler tube. I used 4 cans of the window and door product. I waited 8 hours then tapped on the roof. I used to get a tin can sound. Now I get a deep base THUNK.....WHOA....! My project is now complete thanks to great stuff...!

Rated 4 out of 5 by from More information I couldn't find anywhere to get more detailed information on this product so I thought I'd ask here. My ham radio club is contemplating building our own "hard line coaxial cable" for a remote radio repeater. We need a product to, well, "spray down the inside of a length of (copper or aluminum) tubing to insulate the center conductor from the outside shield". We need to know how far this will expand into a 1" inner diameter tube and more importantly, what is the "dielectric constant" of the product. Incidentally, I have used this product on occasion around the home and have found it to work well.

Rated 3 out of 5 by from Great if you can get it to work! Although the product seems very effective, I found it to be extremely difficult to use. The directions say to apply it slowly, but my applicator tool had only two speeds: nothing and full throttle. The applicator needs to be much more touch-sensitive!! In addition, when I took off the plastic, the applicator was broken. Fortunately, I bought two cans so I had a back-up applicator. Bottom-line: despite its effectiveness, I will be looking for a different product on my next project.

Rated 5 out of 5 by from Good Grief Great Stuff As a new user of Great Stuff, I knew what it was supposed to do but was not sure how much to spray on - after spraying around my 4th window I finally figured out how to control the flow better and how to keep it out of my hair (!). It sealed all the gaps in my new windows and was easy to scrape or slice away when it cured. It really is great stuff!

Rated 5 out of 5 by from Hey, this stuff works! DIY homeowner. Used it around the bases if garage access--3 foot--doors, in areas too large for silicone caulking. AWESOME! Filled 'em right up. Then just trim away the excess, Bingo Bango Bongo. Ready for primer and painting. Would definitely recommend it. Have some acetone ready--if you get any on your hands. Have fun. Jay

Rated 4 out of 5 by from Good product works well All the great stuff products work well. I use them often. It would be nice if they would offer a canned foam that works in the upright mode. With the current products you have to turn the cans up side down to use them. When going around the top of some windows you cannot fit an upside down can. Perhaps a hose 3x longer would work too?
