I'm replacing some exterior flooring on a porch and want to seal the joints
and cracks with a silicone caulk.
Problem: Some of the joints are quite large. I need to put some sort of
filler in the large spaces before I use the silicone.
I suppose I could stuff some styrofoam in the cracks.
Does this make sense?
Any better ideas?
They make backer material for that purpose. You also might want to consider
polysulfide (Thiokol) rather than silicone. It is used on boats and is a
lot easier to sand/cut flush than silicone. Paintable too.

Will look into polysulfide. Guess it's available at paint stores.
Would the styrofoam be okay for filling large cracks before caulking? I
think styrofoam is nondebiogradable.
I think I made a mistake in earlier caulking by using Durham's Water Putty.
I gather it holds moisture, hence causes rot.
