First time poster..we have a house from the late '20s and are removing the tub/shower liner that the previous owner put in.
The plan is to install tiles, using kerdi-board. The old installation was leaky, the drywall underneath ended up moldy, and water made it to our ceiling in the kitchen because of the poor waterproofing.
The old drywall was not a problem but the upper half is a different beast. What's the best way to remove the concrete that covers the upper half of the shower? Some of it is behind lathe, the rest seems to have nothing holding it in place. Right now I'm just using a crowbar, it works okay but there might be a better way.
Do I need to preserve the lathe too?
