A.Yes. Both glues will
form a bond stronger than the wood itself. The main
difference between the two glues is in application
Both glues belong to a class of glues called
PVAs, because they are based on a resin called
polyvinyl acetate. White glues like
Elmer’s were the first glues of this type
to be introduced. While they are perfectly fine for
gluing wood (and a host of other porous materials),
they do not sand well, tend to run, and have low
initial tack. Yellow glues were developed to
address these problems.
Yellow glues have a higher solids content (they
are thicker than white glues and sand better) and
have tackifiers added to speed assembly time. To
distinguish these improved glues from the older
white glues, manufacturers added a yellow color and
a meaningless designation, calling them "aliphatic"
If you think of yellow glue as white glue with a
higher solids content, some additives and yellow
color, you’re on the right track. Yellow
glues are definitely easier to use and have better
application characteristics but are no different in
strength from white glues.
