I filled a bunch of our walls with the spray foam
Here is what I learned after a few different trys
If you use the stuff that advertises Double Expansion, it will actually bow the wall out, so I stopped using that
I now just get the normal can that is normal expansion. I make sure I leave the screw out of the wall which is where I put the straw into
This allows any of the excess foam to come out that hole. Give it a day to dry, and cut with an exacto knife anything that foamed out the hole, put the screw back in and you're good to go
I cant be held liable for anything that happens to your door.
