advice on parging walls during basement remodel
We're slowly finishing our daylight basement (~750 sq ft, 1920s house, PNW) in a house we bought recently. I refinished half already, now we're moving over to this rickety staircase (first and second pic). The clearance is unfortunately too tight to frame out and rebuild the staircase away from this basement wall.
My current plan is to bring the basement framing up close to the landing, remove the existing basement paint, and parge the walls to fill any voids. I have been skim coating the basement floor to fill any voids and make it walkable. I just finished waterproofing the exterior wall on this side and installing a perimeter drain, so I'm not too worried about water intrusion and our basement is fairly shallow (3 feet at its deepest).
What are people's experience with parging? Is it a waste of time? will the parging eventually fail and bubble off, the way that drylock does? I'll note that this wall on the other side, that has not been waterproofed on the exterior (yet) appears to have a very poor attempt at parging that bubbled off at some point, likely from moisture (last pic)
