You will need to remove any loose paint on the existing walls. Loose paint weakens the bonds of the new basement waterproofing paint. Be sure to use proper safety attire when removing paint. Safety glasses or goggles are a must, and a respirator or dust mask is highly recommended. Remember to protect yourself when doing any work around the house. -
Is the interior wall, where the leak is, is that bare? Can you see the leak from inside? -
the interior wall is under the staircase and the exterior portion is mostly covered with dirt. i am assuming that at the exterior portion where the original sealant was painted on is now no longer effective. we had used a black pitch on it. i also assumed it was protected forever....i need to access under the staircase also. very difficult to maneuver but possible. -
I recommend Water plug. "Hydraulic cement" fill the cracks & holes flush with the surface of the wall. Then trowel on a 1/16" layer over the general area.

Exterior waterproofing seldom works long term. It will clog. If it is coming in at the base of the wall or through the wall you may want to address it with an interior system. If it's coming from the top of the wall and running down, you may want to check your landscaping outside.
