Black Mould

If you have windows in that room, it's best to just leave them a bit open - it'll allow fresh air to pass in and that might reduce the spread for the time being

It forms on surfaces at or below the dew point. It can happen at temps above 14c.

I think that Phil just means that at 14 degrees,, mould Will and does form

slightly off topic, but can I ask how people live with a temperature of between 14 and 18 degrees in a house? isn't the whole idea of a house that it's nice, warm and cosy and doesn't replicate the temperature outside on a chilly day?

I would literally shiver at those temperatures and I wear normal clothing inside in the winter (trousers, socks, t-shirt, long sleeve top).

We only have the heating on for an hour in the evening - set at 19oC. In our house, you are either busy doing something so don't feel the cold, or you are tucked up on the sofa with a cosy blanket watching TV/reading etc. Fortunately the kitchen warms up from cooking tea so we can dine in a comfortable temperature. 

Similarly we don't generally feel the cold - we have never hit the point where the radiators cut out through their thermostats

Our dehumidifier meter reckons that our house humiity averages 65% - does that sound acceptible ?

Dew Point Calculator
If you go on this site and put in 65% R/H and the temp of 14C the dew point of any surface is 7.5C. If you get a surface thermometer it will point to any surface getting condensation forming.

White vinegar also deals with mould very effectively - I've got a (glass) bottle of the Sarsons stuff, and an old spray nozzle from an anti bac spray fitted on top, so I use that rather than bleach.

65% sounds a little high, ours is about 50% these days - when it was 65% we had a bit of a mould problem.

OK How do we reduce it to more reasonable levels ?

If we leave the dehumidifier on for 24 hours - and get the humidity down - won't the moisture re-enter the house when the fronr door is opened ?

Bleach tends to remove mould on the surface but not get to the roots inside the materials it is growing on, mould cleaners should have additional ingredients that kill it off properly.
