I live in an old old building. All hardwood floors. In between the
floorboards is this stuff. Black and sometimes tan stuff. Used to fill
Looks like this, with the "|'s" being the stuff:
Here is a photo:
Well that black stuff is in need of a refilling in several areas where
it has chipped out. The missing areas are causing cold air to come up
from the storage area on the first floor.
What is that stuff? Caulking? I imagine I'd need to put something in
there that could expand and contract when the temperature changes.
I would need the stuff to be black. I do NOT want to have to do any
sanding or staining whatever I put in there. I want to do this as
cheaply as possible.
Thanks a bunch,
