Does anyone know what it is and how to deal with it please?

Thank you in advance for helping

Moisture in the air condensing out and going mouldy.

Ventilate or use a dehumidifier .

Stevie_Palimo

It is mould and mildew forming due to the room having a build up of excess water and not enough ventilation and or a underlying damp problem somewhere.

Clean with bleach first and then add a layer of slightly watered down pva glue before adding a mould proof paint and then sorting the issue of either poor ventilation and or damp, If it is the bathroom then you need an extractor fan and if the below is a bedroom or other area then you need look at where the damp is coming in from and fix it, You can use the dehumidifiers and the plastic window seal versions to ease the problem but should look at the course of this and resolve.

Hi both thank you for the replies.

1) Yes the first photo room barely has any ventilation.

2) The second photo is the bathroom, it already has a ventilator fan and I tend to leave the bathroom window open for 10hrs a day every day. What do I need to do more?

I am quite new to this so may be asking some basic questions!

Heating. Bathrooms need to be warm as well.

- What is the set-up of the house (eg is the area on an external wall)?

- What is the age of the house (eg is it a modern era one or, for instance, Victorian)?

Hi,

It came back into one of the bedrooms again.

The house is probably built in 1930's and it is a concrete build.

I posted this solution several times in this forum. But yeah winter is here and more questions related mould.

Try this one - http://amzn.to/2hquH4p - You wouldn't be disappointed. It's a dehumidifier with a humidity sensor. So works smart - knows when to switch on and when to shutdown depending on a preset that you choose.

Apart from that, keep the rooms at optimum heat - around 18C, allow fresh air every now and then.

All the best.

Just so that you know, there is no point in opening your bathroom window for too long in Winter.

When you take shower moisture builds up, so opening it then means you vent it out. Keeping it open for too long means the moisture in the winter air finds its way into your bathroom (or any room for that matter).

So, in winters, open the windows when you see condensation on the glass otherwise keep them shut and keep the rooms warm.

Clean with bleach and re-paint with a suitable paint if necessary - yes - but why on earth would you put PVA over it first? Don't put PVA on any surface you intend to paint.

If your already venting then heating also. 10 hrs per day with the window open is probably creating a cold spot in the house, the air moves from the warm room to the cold room and condenses, as it finds a cold surface.
