OK!  After periods of heavy soaking rains we get lots of calls from people
that have leaks around their chimneys.  99 percent are from chimneys that do
not have through flashing.  There are several roofers in our area that seal
the brick from the outside and have been doing so for many years, especially
Geocel 2310 ("a proprietary ethylene tripolymer formulation").  We all have
discussed the merits of silanes and siloxanes vs acrylics, meineral waxes,
urathanes, and silicone resins, but it is very hard to convince an owner to
do a partial or full chimney rebuild and install through flashing for 3 to 8
grand vs a cure that works for five or ten years and costs a few hundred
bucks.  I have seen chimneys coated with products like "Chimney Saver" over
ten years ago, and the brick is not spalled, the mortar looks similar, but
there are no wind driven leaks, or leaks after long periods of rain.

What up doctors?

Best,

Leland
