Do I have to clean out and replace the Great Stuff?
I have been back-side and edge sealing and also sealing the gaps on the inside of electrical boxes with Great Stuff Door and Window (low expansion foam). Then today I saw a blog that says Dow advises not to contact it with copper wire. I called them and they said its flammable during installation and when cured.
Do I have to clean out the Great Stuff and switch to another product for air sealing electrical boxes? If so, any suggestions.
Thanks in advance
