what can be done with mould through condensation on an out side wall in a bedroom?

Answer 1

bleach

Answer 2

Clean the mould off with mould cleanser/inhibitor, you can get a tea tree one that's not toxic. If you are painting the wall, you'll need to use the cleanser regularly and make sure you don't put any furniture tight against the wall.

Some outside walls that face into prevailing winter weather are
more prone to condensation and need to be insulated against the cold and damp.

If you're going to wallpaper which is really far better, either paste up thin polystyrene which is sold by the roll and then wallpaper over the top or use blown vinyl wallpaper if you can bear it. Once this has been done, when you feel the wall, it's much warmer.

As it was the previous cold temperature of the wall meeting the warm air in the room that caused the condensation, it will then be fixed. We've not seen any mould since we've used this method and it was very bad before.

Answer 3

Clean the mould with a good mould remover and paint with a mouldshield paint (Dulux or Johnstones) or alternatively a product called Permawhite made by Zinseer this has a mould inhibitor in it and is very good.Had this problem in my bathroom it needed doing every six months did it 3yrs ago with permawhite and havnt touched it since

Answer 4

i would think you need an airvent of some sort an airbrick may be helpfull or a vent in your window you need to treat the cause first condensation is caused by lack of air circulation deal with this first and the mould should dissapear and make sure it is not coming from a leaky roof good luck

Answer 5

Bleach will not kill the mold. Clean with detergent and water. If the mold is only on the window sill, this is common. Lower the humidity in the house. If there is moisture in the wall, you have a bigger problem that must be corrected or the mold will continue to prosper.

Consult a professional to make a positive determination. Email e with any questions you may have.

Answer 6

After you have used any of the other answers to remove the mould if there is any you need circulating air modern houses don't have this dew to Central heating and double glazing just open your windows or fit air vents and air bricks. It's the only way.
