@jrxjjeep Hey guy, it doesn’t matter if it's limestone, brick, cinderblock, concrete, stucco, etc. If your basement allows, pressure wash it with minimum 3000 lb. force these are usually gas powered. You can rent one for about 60 bucks a day. Then apply a bonding agent and use whatever material you want to skim. The key is the surface preparation. I will send you a link to one we did very similar probably in worse condition. oppps, it wont allow the link

@StuccoPlastering thanks for the idea of the bonding thats what i will do.i think with the power washer the wall will fall apart.thanks

@jrxjjeep Hey guy, the bonding agent won’t work if the wall has dust, dirt, or mold on it. That's why I suggested power washing. If you apply a bonding agent over a weak wall the stucco will adhere to the bonding agent but the soft wall beneath can possible come off.

Best wishes.
