Great Stuff Expanding Foam

[cc_audio]

When its cold you need to shake the can longer, much longer. We have more than ten cans of great stuff on the shelf right now. Cold weather is really hard on the stuff. Never had a problem with it drying in the cold, its more the problem of having a cold can. Before you use great stuff keep it in your house or in a well heated garage for a while. Otherwise you have to shake for, no joke, five minutes or more. The reason it didn't set up in those few spots is you didn't shake it long enough. It will harden, but it will take a significantly longer amount of time. But it is GREAT STUFF!!! As seen on TV!

heat gun maybe your friend. be careful with it and go slow. it can cause bulges if it has no where to go.

more of that shit leaked this morning thank god it dries once it leaks so I can just peal it right off the plastic.

it sucks because it won't dry behind the duct tape but once it gets exposed it dries instantly so I tried getting air to some of the wet stuff but then it ends up expanding and leaking out :censored:

I need to start over and do it right... put it in some warm water then shake it forever then do it during the day

good luck starting over man. i hated removing this when i would mess up. its so hard to remove and not fun. i would suggest to use like a hair dryer or a heat gun just so that you dont have to deal with removing it. i mean its already there, it just needs to harden and dry..

I'll leave whats there since right now its just like a half inch layer covering the hole with nothing behind it and then just fill it all in behind it

hmm ive never had a prob and im in MN too lol but havent workied ouside with it since it got cooler out. id say maybe toss some platic down on your seats and leave your truck rnning with the heater/defroster on to get the temp up. leave the windows just cracked for ventalation. not sure if it will help but maybe try replacing some of the duct tape with masking tape..? mabey since its a lil thinner it might help dry that up a bit. shit should dry up though with a lil more heat. let it get nice n warm with it running though see what happens.

Also be careful not to burn you paint either....I used a different kind of expanding foam its a non warping kind....its not as rigid but it better than having a bulged warped roof....

This is what I used...

I was gonna try this but I didn't want bulges and warped sheetmetal

Where did you get that foam at?

I think it need to have some contact with the air to dry.

i tried to make a mold with the foam before. but the inside of the mold never dried. it always ended up a big wet bubble. Ive also heard of it happening when i guy tried to level out part the rear cab of his truck. He layed a board down and sprayed the foam under it. and it never dried untill he took the board off.

It might be somethin to do with humidity though(corresponding to needing to contact air). The can should say somethin about it works better in moist air or somethin. It says misting it with water will help to cure better.
