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.
