My condo development has had problems with rotting wood siding on the
buildings. I'm told this was due to the quality of the wood being poor.
The Association has always been using solid colored stain instead of
paint. The stuff, to me looks like just like paint, but my understanding
is that, because it is classified as a stain, only one coat of the stuff
needs to be applied, and without any primer. For this reason, I'm
wondering if the use of a solid colored stain instead of paint might
contributing to the wood rotting.

Would properly applying one coat of a quality solid-colored stain provide
as much protection as if the building were properly painted (which I
assume would entail a primer plus 2 coats of quality paint). Am I wrong
to be suspecting that solid colored stain is being chosen as a means of
saving money....I'm imagining them saying.... "solid colored stain is
great because we can just apply ONE coat of stain and be done with it
rather than having to pay for the labor of applying....oh my god.... a
primer plus....oh my god.... two....yes two.....coats of paint."

Am I wrong to be thinking that the buildings would be better protected if
properly painted rather than stained.

The basic assumption that the siding is faulty may be a bad rap.. What kind
of siding is it? Could be the direction of exposure, roof/eaves leaks,
leaking gutters, lack of proper overhang of the eaves, etc etc. I would
have an expert look at just where the rotting is occurring, and why, before
you decide what sort of coating to use, which is of secondary importance..
Re comparative cost, the Cabots solid color opaque stains I use on my decks
and rails are every bit as expensive as exterior paints.. Stains in some
applications may be more effective, as they soak into the wood more, and
tend to resist flaking if properly applied. If you have moisture moving from
behind the siding outwards, paint with prime might be a poor choice, as it
would form a good water seal, then pooch out in flakes, as the water
debonded the primer.
.. Bottom Line - get an expert on drainage and wood rot, and get his opinion
exactly why the siding is failing. A number of siding brands have been the
target of legal action, due to poor quality binding, material, or adhesives.
