Many of the wooden quoins (corner blocks) on our 1870's Italianate
house have cracks and gaps in them.

I'm looking for a filler that would have the following properties:
- Paintable
- Sandable
- Exterior grade
- Able to withstand seasonal expansion/contraction cycles

Any suggestions?

I tried caulk, but it leaves a very messy result since it is not
sandable and leaves a rough film

I tried woodfill but it doesn't seem to hold up to the
expansion/contraction cycles

Thanks

You probably used the wrong caulk .

For exterior fills such as you want use silicon caulk which is paintable.

After you pump the caulk into the cracks wet your finger and smooth the lumps down.
If you apply the caulk with discretion you will not need a wet finger or sanding.

Be sure to read the labels as there is silicon caulk which is not paintable.

If you want a crack filler for wood, then epoxy and micro-balloons.

If you need a caulk, talk to SikaFlex tech service in Detroit (800#)
for an industrial version of 291 used in marine work.

I find that silicon caulks look even more caulk-like than the
latex-based caulks and that they are harder to work. And since they
are not workable or sandable after hardening, I don't know how you can
get a seamless repair. But maybe I am missing something here...

I really want something that will look and behave like wood so it will
fully blend in.

He said I could paint it, but the paint just crawls off. Now what?

A: We have heard this one more times than you would believe. NOTHING
will EVER make 100%% silicon caulk paintable. Not primer, not time, not
crying or praying. All you can do is scrape it all out, then re-caulk
with a painter's silconIZED acrylic caulk. And hope you don't have to
buy a new trim package."
