How would you treat this mould?

On a wall near the shower. Does anybody have a dehumidifier in their bathroom? How is it powered?

Hopeful bump

We had a dehumidifier in our last house which seemed constantly damp and mpuldy. Mains powered so sat on the landing outside the bathroom. It did well at stopping mould getting worse, but the only way to really stop it was to clean it up (I used anti bac wipes and then a spray with dettol) and then apply anti mould paint before re painting with the right colour. I'm sure there are better ways to do it but it was a fairly quick solution for us that seemed to work.
It's also worth seeing if you can work out what's causing it. If it's near the shower, is it getting splashed and could you stop that happening? If it's just general dampness then it's not so easy.

Astonish mould and Mildew spray! Leave on for 5 mins then wipe. Then get a dehumidifier from willow with the disposable centres. About £10 and a fiver for a refill

Mould will grow wherever there is damp.

Damp is water.

Showers spray steam and water into the room. You have to get it out.

have you got an extractor fan? Does it work effectively? (obviously not, unless it is turned off). Show us a pic.

Also, show us a wide angle pic of the whole wall. It looks like that particular patch is caused by water running down into that corner.

Yes I have an extractor fan which isn't effective enough. I think that adding a dehumidifier will be cheaper than replacing the fan.

The wall is at the end of a walk in shower. I have added a shower curtain to protect the wall. obviously not great to look at but the cheapest solution so I think I have sorted the problem of the wall getting wet.

The issue now is what to do to sort the wall.

If I spray with a mould spray, sand it down and then paint with a mould resistant paint before painting will that be enough? Or do I need to do something else?

@Somewhereovertheroad - depending on what's caused it, I reckon that should be enough. It would have worked for the mould in our last house at least. Sometimes just cleaning it off is enough (agree the anti mould sprays are good - cillit bang do a good one) but if its well established it often just comes back.
It's a bit depressing I know so much about mould! It became a bit of an obsession for me!

@Wavingwhiledrowning Did you try a dehumidifier?

Yep - had a pretty big one! It collected a ridiculous amount of moisture every day. Did keep the mould at bay (mostly) but we still had to clean it all up first. Lesson learnt with that house - don't live next to a river in a dip. You might as well live in a cloud. So, so damp!

A large part of the problem is that we have a mechanical ventilation unit which doesn't seem to be adequate for the house.
