Tiling in the basement plaster or concrete block

[mickimike]

The plaster has come off a lot, wondering if it's easier to remove all the plaster and tile on the concrete hollow blocks or is it extra work to replaster first?

You might have to knock off quite a lot of plaster anyway if you're going to replaster?

I knocked off all the plaster.
Then, since the concrete block wasn't completely even, I glued waterproof boards with adhesive onto the walls.

I chipped off all the plaster.
Then the concrete hole stone wasn't completely even, so I glued wet room boards with adhesive on the walls.

all the loose material is gone, planning to sand down to remove the paint since I don't think it's the right paint. but the question was if you could tile directly on concrete hole stone instead of doing the extra work to plaster first

The walls must be completely straight when setting tiles, so either plaster them or, as Bruk writes, glue a board.

Plastered walls are not particularly straight then.

Well, if you polish them straight.
