I've used DAP and Red Devil for narrow cracks. CHeck the labels. They make
stuff rated excellent for cracks. If the crack goes below the surface
squeeze in some backer rod first.

Hi,

Thanks for reply re my old post on fixing a crack in drywall.

Might you suggest a specific "flexible" filler ?

Thanks,
Bob

How wide is the crack ? You might be able to find a flexible filler that
can
handle it without tape.
