Just curious, did you paint over that with drylok? I can’t tell if that’s closed cell foam. But to my understanding unless you drylok gap and crack foams, they offgas toxic fumes for years. If you seal with drylok the fumes can’t escape.
Alternatively, pond and stone foams of any brand are...
Isn’t that great stuff foam the toxic one? As I understand only the pond and stone foams are pet and UV safe, the rest break down and slowly off gas, especially if they are not closed cell foam…
