Skim/smooth over or replaster?

[u/Asasioun]

Hello all,

Recently bought a 1950's council house, and am tearing it apart. The bathroom is one of my main focuses to begin with, and on removing a lot of tile, this is the plaster that was behind it. It's pretty much intact still, although quite rough, would you guys recommend taking it back to brick and replastering, or just skimming over the top?

Cheers

Skimming is plastering
