Every couple of years, cracks in my drywall keep reappearing in more
or less the same spot. I resurface them with drywall compound, repaint
and sure enough, they come back.
The cracks are very small(possibly due to a weak spot susceptible to
freeze-thaw shifting of the house foundation) ..... is there are more
flexible product I could use to cover them up? Drywall compound is too
brittle and does not do the trick.
Any suggestions would be much appreciated.
Thanks ..... what a great forum! Wish I would have discovered it years

I endorse this solution. I had a drywall cracking issue in one bedroom at the
corner of my house where I had freeze/thaw foundation issues. The foundation
was later upgraded, but the drywall cracking was repaired using the mesh tape
before that, and held up well over a couple of seasonal cycles before then.
Worked amazingly well.
I too recommend the fiberglass tape. I had an old house in Los Angeles
where one corner over a door cracked very badly every year. I must have
repaired that crack half a dozen times before I used the tape. After using
the tape I never had another crack over that door for the rest of the time
I lived in that house which was about twelve years.
I think the choice between elastic caulk and mesh tape depends on how
bad the cracks are, how many they are, and how much work you want to
do. The caulk is proably more likely to have to be redone, but the
mesh will be noticablly thick and noticeably meshy and will have to
have a lot of stuff put over it to cover the mesh. And it might be
easier to do the caulk 2 or 3 times than the mesh even once.
There are caulk or spackle-type products, special for cracks, that are
elastic. I forget the names but the paint store guy will know.
There's a dozen of products -- hard to say which will be
best for your specific problem.
However, it sounds like you need something a lot more
flexible/elastic than what you've used in the past.
Bear in mind, those products are likely not sandable!
You'll need to apply it correctly, first time. Spend
a few minutes playing with the gunk and an old bit of
sheetrock, cardboard or whatever just to get the "feel"
of the stuff.
You probably don't want to go for the ultimate in
flexibility (i.e. silcone) since that is neither
sandable nor paintable.
One problem I have found with many of the more flexible
fillers is that they shrink during the cure. That's
only likely to be a problem if the cracks are large.
Alternatively, you might consider applying a textured
finish to the entire wall/room. This can be done using
relatively flexible mixes that may absorb the movement
well enough. Even if some minor cracking does come
through, it will likely be a lot less visible. Hairline
cracks are a hugely less obvious on textured versus
