The ceiling above my shower is suffering from mould. There is not much ventilation in my bathroom. We always open the window after a shower. How can I get rid of the mould that is already there. And how can I stop it returning? Thanks.

Clean the mould off with some sugar soap and then paint your ceiling with Zinsser Perma white. The mould will eventually come back but not as quick as if you use normal bathroom/vinyl silk etc

Thanks telboy. Will give it a go.
