Hi! I am at a loss. I have a porch that I believe is made of concrete with a plaster mix overtop of it. It might be all concrete. The house is around 100 yrs old. The paint is chipping and just gross looking now. I was taking a scrapper and removing it to prepare to repaint. But whatever the material is keeps crumbling. I was told I could use a sand blaster to remove the paint but I'm afraid it would decimate the porch.. attached is part of the column.... any suggestions? Thank you for your time.

we'd use an aurand to remove the failed applied coating ( might be plaster, might be mortar ) but we own them,,, you have to think bushing tool + small demo hammer - #30-#35 class,,, maybe even brick chisel bit or wire brush & 4" grinder,,, all depends on your age & how long you want to work on this
you're right about sandblasting - even if you use walnut shells, you'll damage the conc
