I've heard HG is good - thanks.

Hate artex, might get a quote for skimming, it's just the bathroom. So can the the mould be plastered over?

Good plan, the HG spray is inexpensive.

The last time I had this done (a good few years now), the plasterer knocked off any big protrusions before skimming, to minimise the depth of coat needed. I assume any plasterer doing that should check for asbestos.

HG Foam mould remover isn't recommended for ceilings. Will check to see if their other mould remover is suitable.

Never tried (nor was I aware of) the foam, only the "normal" spray.

When we put our flat on the market about a decade ago, it was my job to clean it after we'd moved out. Quite a few patches of wall had mould showing and I'd tried a couple of supposed mould removers from the supermarket with little success. Someone recommended the HG (which I got from a well known DIY place), so I got some and used it. Honestly, it was a revelation how well it worked. Spray it on, leave it for a bit, wipe off, mould gone!.

Another vote for the HG spray - seems to work much better than anything else. Have used the foam spray on ceilings without an issue.

Thanks to all for the info, very helpful!

You could really do with an extractor fan, timed to stay on for a decent amount of time after light has been switched off. A ventilator slot won't be enough, especially if the door is closed.

I strongly agree re the need for an extractor fan. I myself have a loft mounted fan assembly (Manrose MF100T - T for timer) with 100mm ducting from the bathroom and beyond the fan to an external vent. I also fitted a one way valve to avoid draughts when off. Very quiet running, low wattage power consumption but very efficient. All you hear in the bathroom is "sucking" and it's all but silent in adjacent rooms. Very useful for drying washing over the bath and I've never had a mold issue sine fitting quite a few years ago.

I originally also had stippled Artex but had it skimmed when I was tarting up the bathroom.

I had mould in several rooms, and when my tumble dryer went south, bought a dehum to dry the laundry. Well what do you know, running it a few hours a day prevents mould, and costs about 7p an hour, peanuts. It’s much cheaper to run than a tumble dryer, and wastes no water. I leave the bathroom door open.
