Plaster over interior concrete wall
My basement is composed of uneven interior concrete walls. Years ago someone put plaster on top, and now it's all coming off. What do people recommend to put on top of the concrete? I've never plastered over concrete before. Some people are recommending mortar instead of plaster, but I'm getting a lot of conflicting opinions. Any suggestions?

Welcome to the forums.
First question would be why the plaster failed. Likely in my mind that it was due to moisture moving through the wall and that would need to be addressed.

Thank you!
The basement has and will always be somewhat moist, there's nothing I can do about that. I believe overtime the plaster started to dampen and fall off in certain places. Which is why I'm hesitant about putting plaster on again.

Do you know if it was really plaster? or just joint compound?
The most generally accepted way to cover a basement wall is to frame out a wall an inch away from the block. You can then run wire and whatever in the stud cavities and use traditional wall covering over the studs.

As long as there's significant moisture coming through the wall, anything on the wall is going to fail.

Having an air gap between the studs and the foundation wall limits the likelihood of mold or any moisture damage to the studs or the drywall. Also it's better to not have to punch any holes in the foundation wall with nails or screws.
You first want to make sure you've done everything you can to make the interior side of the foundation wall dry!!
