Mould is normally caused by damp. You need to get rid of the damp. I'd recommend seeing a specialist.

50% Bleach and 50% Boiling Water was what worked best in the flat I used to live in. It needs to be done on a regular basis though as it is not a permanent fix. Sorry I could not be of more help.

I would not seal walls with anything, bricks are meant to breath and using a sealer will not work, the damp will just find somewhere else to come out. I would try installing airbricks, you will be surprised by the results.

You seal the walls to stop the damp getting in, in the first place. The bricks don't breath as most properties don't have cavities. I coated my walls with Tri-Metal Fix 15ytl from Marshalls that will seal the walls and stop the damp, providing its damp. Condensation causes the same problems if the rooms aren't aired on a regular basis...........

think it is different for old and new houses.

we lived in a listed cottage in the uk and when we had the damp specialist in he told us that the house does have to breath and not to use those plastic based paints on the outside of the buliding.

Hi....first thing is to identify the cause....if it is high up it will be a missing / broken roof tile / guttering or broken down pipe.



If it is under the window, the rain on your window ledge will be leaking back in



If low in a corner...the exterior wall is not sealed.



To kill moss...use indiluted bleach and leave.....note this is also a great way to get rid of those "Black" dirty patches on tile grouting in bath and shower areas ( just leave overnight after rubbbing in with an old tooth brush! )



Do not reseal any wall untill it is thoroughly dry





hope this helps

Hi

Bleach will kill the mold spores, but you may have to paint over to completely rid the walls of the stain.

What do you think created the mold, is it damp from the ground?, this is indicated by the mold only coming up the walls by a little less than a metre, you would not have a mold issue upstairs

If the property is closed up during the winter you will possibly get cold spots in the property, behind a piece of furniture or on a outside wall in the top corners of a room. This is created from the property warming up during the day becoming very cold in the evening. As air hits a cold surface, it turns to moisture.

Ventilation would help. but also a dehumidifier, unfortunately this would require attention as you would need to have it emptied regularly. If you think it is raising damp You could try taking away soil from the outer edge of the property fill with gravel, waterproof.

A listed building would have old fashioned mortar this type of mortar needs to expand/contract

hello peeps,

my freind had this problem in a flat she was renting out, it was caused with people doing a lot of laundry in the place, so open windows, and air the place and dont keep curtains shut, dont use tumble driers when the doors and windows are shut iether as this all helps.

i honestly think none have the remady for each unit here there are many factors 1 if your air con unit is above the entrance to your building this when it rains will run down the pipes into your wall . these bricks are cavitntated with chanels you could never tell were that would end mid building or bottom you cant tell and could also suck up when dry you cant inject because unlike england there is no positif cavaty so thats that but windows open will help

For sillicone around showers and grout lines etc. 'Dettol mould and mildew remover' works wonders, it is in a green plastic spray bottle and sold in most supermarkets in Uk (not sure about TRNC). Also great on shower curtains before washing them. It will remove black spots from painted walls, but these always come back eventually unless after black spots are removed you use a stain block paint, followed by final coat of bathroom paint. Hope this helps.

Firstly to kill and remove mould bleach/sodium hypoklorit is very good. Only about a 5% solution is needed, a 50% is a bit dangerous and smelly. The branded mould killers are only expensive repackaging of bleach.You are right condensation more than rising damp is most likely the cause. Mould is often in the top corners of less used rooms, commonly nearer the outer ie cooler walls. Airbricks, or hit and miss vents on windows will probably be sufficient in many cases. The removal of internally created damp, washing, cooking showers and people (cannot do much about them!) is important, open windows, extractors on cooker hoods, showers leading to the outside.If anyone uses a tumble dryer they realy must be vented to the outside. A reasonable measure of the level of humidity is 'do your windows have condensation on them on cool mornings?' Flat have a smaller cubic volume and are more prone to condensation problems.

and can fit hit andf miss vents, ducts for dryers and cooker hoods. Fire starter is right, the usual remedy by locals is to paint over he walls with a waterproof paint is wrong. Some of the very expensive 'microporous paints are OK but the walls inside and out must breathe. The solution to damp is three pronged. Remove the source of damp, dry the area out and make good. Simple really. De humidifiers as a remedial action are good but should not be required for long term use. I see trays of salt was suggested as a damp absorber, yes it works but tons would be needed.

Any advise on removing the damp patches from the leather sofa which was left outside on the veranda? Tried the bleach advise but it helped very little. Anybody knows other solutions?
