Answer 2

The answer above is very good, but without knowing where the mold is occuring, we have to be general.

To begin with, moisture moves to cold. Notice how a cold drink condenses moisture? Well a room that you don't heat in the winter will do the same thing. If you open the room then close it back up, you will trap the moisture and it will start the mold.

I see this all the time in my rentals, where they closed a room up to cut heating bills.

As mentioned, use bleach of some sort the kill the spores, then prime and paint the wall.

There is a new product out that stops mold dead. It was actually delveloped to stop terrorist attack from anthrax. I have read about it, but can't tell you were to get it. It is being sold over the counter and for mold prevention.

Good Luck.

To stop mould you must have good ventilation and good heating. You can clean it off but it will return unless you stop the cause. Fitting extractor fans in the kitchen and bathroom will help. Steam from cooking/Shower etc. will find its way upstairs if you leave the doors open and will condensate onto ceiling and any glass it comes into contact with. Mould is a growth that occurs when a cold surface is under constant bombardment from steam particles. There are specialist paints available ie. "No More Damp" is one brand that have special chemicals to stop damp from forming. I used it at the top of my stairs and it did eliminate my problem. Only good for small areas though and it is expensive. There are also special paints called Thermal paints. They contain thermal granules which when dry provide a thin thermal barrier between the wall and the top coat of paint. This stuff is very expensive but it does work as steam will not condensate on warm surfaces. Foam insulation can be injected into the wall cavity and works well especially on weather facing walls. On older houses you can fit insulation sheets to the inside walls and cover over with plasterboard and skim. Gas fires will release their gas water content into the air and we are talking cupfuls over the course of the day and night. You can't see this until the gas water content hits your windows. Also check for cracks on the outside of your property as water ingress will often be the cause of damp patches. Mould spores love those damp patches. Ventilation is really important. Fit vents inside wherever you can. At least two to each room. Just above the door is a good place, but you can fit them into the floor if you have a wooden suspended floor. A house has to breathe. We seal them up with fitted carpets and double glazing, draught excluders, and moisture cannot escape anywhere. Fresh air supply is the key with vent outlets to keep the air circulating. Can't think of anymore. Oh yeah one more thing, we breathe out a lot of water in our sleep so make sure you have an open vent during the night.

Answer 4

Mould is usualy caused by too much dampness in the atmosphere of the room. A house that has full uPVC double glazing and doors is hermetically sealed and the house can't "breath".
You need to try and open the windows for at least some part of the day and sleep with one slightly open at night.
Ordinary household bleach will remove the mould already there.

Answer 5

Thompson's do a paint that will treat and kill the mould and cover it at the same time also somebody told me a large bowl of salt in the room will take some of the moisture out of the air good luck

Answer 6

Best thing to use is a small spray bottle with Clorox bleach, to spray on the walls. Also, if this is the lavatory, I suggest you wipe down the tiled walls after your shower/bath. Run the fan before, during and after your shower. Do not close the bathroom door for a few hours. You want alot of ventilation. If you have a window you may want to open it for air to circulate. Good luck!!!

Answer 7

you can buy a cleaning solution to remove and kill the mould spores and they don't come back. Readily available in D I Y shops

Answer 8

Answer 9

Get a dehumidifier, they dry out the air. Also depending on where you live, climate wise, either open your windows for dry air, or close them to keep the moist air out.
