The DAP package says: "A premium quality all-purpose patching product
for the repair of cracks, holes and defects on interior wood
surfaces."

The water putty comes as a dry powder that looks just like the gypsum
in setting joint compound. After adding water, it also looks and
works just like 20 minute setting joint. The only difference that I
have noticed is that it seems to set harder and be more difficult to
sand.

So, what is the (official) difference in formulations and properties
of "Water Putty" (whether DAP or Durham) vs. standard setting joint
compound?

what does the package say? if not there, the msds will have the
differences. what does it say?

Bottom line , Joint compound is for sheetrock...The Water Putty is for
wood...It's BEST to use the correct product for the job...ESPECIALLY if you
are using it for a customer...If **** goes WRONG the manufacturer won't
stand behind you and YOU will eat it , so to speak...LOL...If at home and
you want to experiment...Go for it...Let us know how it works
out...LOL...Hope I helped....
