Minifridge door foam

I need some opinions. After hacking at my mini's door, i have exposed the insulation foam. Can this foam stay exposed? Or does it have to be covered? What have others done in order to cover it up? I tried duct tape but it came unglued after a few hours. I need some ideas here. View attachment ImageUploadedByHome Brew1489892321.825671.jpg

 

"In my opinion " with no experience with that particular issue I would probably tape off the door seal and use that flex seal spray, maybe a couple coats. That may help keep it from making a unending mess wit crumbling foam.
Depending on how extensive your labrewatory is... maybe screw or rivet a very thin plywood panel to the now inside edges of the hard plastic. Good luck Partagas.

 

That would make a good place for mould to grow, and its hard to clean. Cover it with a sheet of plastic, I used plastic signage board on mine.

 

You can mix up some casting resin and just flow it over the foam. Let it sit for a day and you will have a plastic panel over the foam

 

1/8" ABS panel worked for me.

 

You can get fiberglass sheets at the home improvement stores. You can use a piece of countertop laminate.(Maybe check for cutoffs...)

I would test a spot before committing to using anything that cures. It might melt the foam before it cures. Solvents and foams often do not get along.

 

I used some self-adhesive padded foil duct insulation you can buy in a roll at home depot. I had it laying around from when I needed to insulate some patchy AC/duct insulation. Probably overkill, but I wanted to make sure the foam was protected from nicks and dings.

 

Thanks everyone for the suggestions. I went with a thin piece of fiberglass and sealed the edges with silicone. However my 6.5 gallon big mouth bubbler still needs a little nudge and squeeze to be able to fit in. Im currently fermenting in it and closing the door with a little help from one of those pressure joint bars ( the name scapes me right now) i think that eventually im going to have to remove it, scrape a little deeper into the foam and i liked the suggestion of a resin cast for it.

^^^^ same here. I used foil tape to clean up all the seams

 

my fermchamber foam has been exposed for years at 65F with not much issue. just dont spill beer on it and you should be fine.
