It is appx. 12 inches long, and 12 inches wide. The hairline crack is
shaped like an L.
Before, I used a putty type substance that was rubbery. I thought it
would take the movement in the wall. I can't remember the name of the
Ok, you could make a drywall mesh repair. The mesh tape self-adheres to
the drywall which you cut to cover the crack to be patched. Using several
light coats of drywall compound, sanding lightly in between and feathering
the edges to blend with the drywall surface. Using the mesh will normally
prevent any crack from reappearing.

We need a picture to get a better understanding of the issue. Is it near a
window or doorway? L shaped is very odd.
Why say that? More than likely telegraphing location of the corner of
the sheet as whatever it is the bulk of the sheet is fastened to settled.
The more key question is why it's still moving and reopening the same
A photo will show this if it is perfectly straight and square. I have seen
straight and angled cracks, but rarely l shaped. When I do see it it is
usually improperly installed drywall around an opening, be it window, door,
or doorway. The photos requested will determine the necessary repair.
Again, assuming a perfectly square and straight crack. We need more info
and a photo. Where exactly on the wall is the crack? I would like a closeup
of the crack and an area photo to look for nearby features.
The OP was quite clear in saying it _isn't_ straight or angled but an
"L". Unlike you, I've seen quite a number where that is the case and
it's clearly the piece moving relative to its neighbors diagonally as
opposed to unidirectionally or a corner that sagged but where the single
piece is tied to (say) header and studs around an opening and hence
cracks the paper (hence the diagonal).
The photos would show the shape of the "L", granted. I submit they
wouldn't necessarily show anything about the "necessary" repair as still
the previous observation holds...
If it is a 12X12 patch that is cracking repeatedly you should take it apart
to find out why...Piling more mesh or tape and mud on top of it will just
make a hump in the wall and it will crack again...Can you post a pic ???
