A friend sends this. Can you offer a suggestion?

 >>Before I knew up from down, I coated the interior of a painted red
brick foundation with thoroughseal. Stopping the wall from breathing has
caused major mortar failures on the exterior bricks. I know Portland
cement will destroy the bricks because it is so hard. What mortar mix
should I use? How should I remove the interior sealer to be able to
repaint the exterior side in spring? Help is needed to fix this mess. 
Thanks, hugely.

had a similar problem in KY a few years ago and the thoroseal was bonded
tight in many places excpet the mortar joints.

It too had been painted prior to the application of thoroseal. That was
what allowed us to remove the coating as theapint provided a bond
breaker

Our solution that worked well was to first use a pneumatic bush hammer
that had dulled teeth.  It was used with light pressure and that knocked
loose the thoroseal.  What did not fall off could be scraped off.

This worked well without damage to the 1865 bricks.  Soft touch was the
key.
