I just thought a thread dedicated to
great stuff expanding foam would be cool to have around. So here is a place to share your experience with the stuff that nightmares are made of (in more ways than one)

. If you have pictures of project you have made with it . Or if you have found out the hard way, as I have ,just how messy it can be to work with.Feel free to post it .
my own rules of the road when using this stuff.
I now wear gloves, safety glasses, long pants, long sleave shirt, stocking cap and shoes that you can throw away. This stuff does not come off your skin without a fight. It will not come out of your hair or your dogs hair.

you and your dog will need a hair cut if some accedently flips into your hair.
Work In a low traffic area with plenty of room to move around and keep kids and pets away.
Heavy gauge plastic sheeting is great to work on. I have sprayed the sheet with WD-40, Silicone, or rubbed on a light coat of lithium grease in the past to keep the foam from sticking to it. If the plastic is new clean and smooth you can get away without using a lubricant of some sort. Once the foam has cured it will peel off of the plastic fairly easy.
Great stuff is rather expensive. so I use an armature when ever possible. I made a nice size chest piece by laying a pile of shop towels on my work table in the ruff shape of a torso. I then covered the towels with heavy duty plastic and then covered that with the foam. It came out nice and gorey looking.
thats all I have time for now.
