Moisture Problems

Robust is currently tackling two jobs with moisture and condensation issues.

We have a medium portable dehumidifier running in a one bed apartment currently with mould issues. The display on the dehumidifier shows the current room humidity. The reading above is 72. Range goes from 0-100. The ideal range for rooms is 40-50. Hence the indicator is showing 72 is high moisture.

Mould and high moisture:

The higher the more humid and the more moisture. This moisture allows mould to grow and makes the room damp and musty.

We plan on seeing how much moisture we can remove from the small room and also will the humidity be possible to lower or will the dehumidifier need be left on to tackle the problem.


Here is the amount of water removed over the course of a weekend, the compartment filled to the top. As you can see it full to the overflow cut off point. This is the magnetic connection to cut off this unit, a good feature.

The humidity levels are being reduced from high 80’s down to 60. Following moisture removal it is a good time to tackle a mould treatment and application of new durable paint.

There is also the industrial option as shown below, this would remove moisture quicker.

Don’t Neglect your Extractor Fan!

Extractor fan are essential, yes essential to the fabric of buildings. Without extractor fans you would get moisture build up which would led to mould as we worryingly found before.

Often extractor are present but not working or the motors have blown on them. Please don’t neglect this issue. You will cause damage to your home or apartment and can allow toxic mould to develop.

There range from the very cheap at 17 euro to 100 euro for 100H BATHROOM HUMIDISTAT fan, both are Compliant with Part F of the Building Regulations. Part F is the  Technical Guidance Document on Ventilation.


Some rooms have fixed louvre vents, these are vented naturally from the environment. Some have a closer to open or close the louvre vents. These are equally important items of ventilation in a house, they are known as passive ventilation.

To summarise check extractor is working and if not get a new one installed immediately.

If you require a tradesman to install one contact Robust for a free quote.

How do I remove Mould?

Robust has put together some of the information we have gathered in regards the difficult and dangerous problem of mould. You can use this advice to clear up your apartment, your house or your rental property. Queries on how do I tackle damp patches and mould patches is a very common question.

Robust recommend:

  1. Prepare the property and yourself by using the correct tools and PPE for the job
  2. Use a Mould Killer such as Ronseals. Follow the instructions carefully. Once clean let dry
  3. When clean and dry apply an anti-mould paint such as Ronseals

What is important to note is that normal paint will not suffice for the problem. Anti mould paint usually costs 25 euro a litre which is up to 4 times the price of standard paint. Anti Mould paint Example or Fleetwood Anti Mould Paint

Other good Mould products we recommend.

Some other options and products for Mould and Mildew: Mould and Mildew cleaner from the Krud Kuttter range. Paint choice of Zinsser Perma White, this is a waterbased paint that will prevent any mould re-appearing. Use these two products you should remove the Mould and Mildew and hopefully stop them appearing again. Mould Paint is best applied as as top coat.
