thompson water seal is junk ,mineral spirits and wax
Buy a product with siloxane in it.
Hydrozo comes to mind ,have used it for over 20 years,excellent product.
Talk to brick makers or commercial concrete product suppliers.
don't buy from the big box stores , go to the people who actually know what
they are doing
a good sealer will come will a guarantee

I have a 50+ year old brick ranch house in coastal VA. During the
N'oreaster of a week or so ago, we had steady 30+ mph winds with (in
our case) 10.9" of rain. Ten days later, we can still see the dry/wet
line on the windward side brick caused by the overhang of the eaves.
Have never had that happen before, and we have gone through lots of
hurricanes.
So, the question arises in my mind, is there some reason I want (or
not want) to seal the exterior brick once it dries out. What's an
apprpreate sealer, if you believe in sealing?

You can put a wanter repellent on but don't try to seal the
birck, it can cause serious damage to the brick, it needs to be able
to breath.

Coat the brick with Thompsons water seal when they have dried. Bricks
do not breath. Those nor'easters are like a three day powerwash.
