In most cases in modern houses with central heating and good damp proofing mould is rare enough but when discovered it is generally found in bathrooms. The heat from showering and bathing causing steam which condenses mostly on the exterior walls of the bathroom eventually causing mould. Mould in bedrooms on exterior walls can also be caused by hot air in the house condensing as it hits the could surface of your exterior wall, again a vent in the room and further insulation will reduce this problem. The bottom line is moisture causes mould.
Killing the mould.
Most strong household bleach will kill mould, but it is not really the most eco friendly way, and one must observe health and safety when using bleach, eye protection, gloves, possibly a mask if needed. Well there are more eco ways of killing mould namely, vinegar sprayed directly on to the effected area and left for a few hours works, then wash away with water. if you do not like the smell of vinegar you can add a few drops of essential oil which will ease the odour.
Tea tree oil is another great natural antibiotic and mould killer mixed with water approximately two teaspoons in a cup of water again sprayed on the surface an left for a few hours. Again rinse with water.
Not forgetting the old reliable baking soda an amazing house cleaning and multi purpose product, mixed with water ( a saturated solution) with a little vinegar applied to surface will kill the mould. then one lightly scrubs and wipes off the area, any stubborn remaining mould gets the concentrated baking soda on a sponge, a light scrub and you are done. This is the best way if you want no odour at all in your bathroom. For more tips look up “Green cleaning solutions”.
Repainting your bathroom.
There are now very good paints on the market that are anti mould and mould resistant paints for bathrooms and kitchens. We recommend using such products. The more expensive ones tend to be the better, but we have found that the coverage is not great, so mixing the product with a normal good quality matt emulsion, about two bathroom paint to one regular matt emulsion, makes for far better coverage with the paint, while still providing the anti fungal properties.
Preventing Mould growing after your fresh paint job.
Moisture, Humidity, condensation, bad ventilation; are all key factors to mould growth. If you live by the sea or a large body of water, your moisture levels in the air are going to be much higher lets say than the city, there fore, the chances of mould growing is greater. In any and all cases moisture levels have to be reduced, the best ways of doing this are, better ventilation in your home particularly in effected rooms. A dehumidifier makes a huge difference as it takes the moisture directly from the air. My advice is by a good one and you will get a laundry setting on it which will dry your home, and your clothing in the winter. Drying cloths inside the home is another major cause of added moisture. You will also find that your heating systems will be much more effective, as non moist air is much easier to heat and uses far less energy. Improving insulation will help greatly as this also warms the air in your home and prevents condensation (warm air hitting cold exterior walls or inner ceilings). Mould lives on organic material, include wood, carpet, food, paper, insulation, wallpaper, paint, wallpaper glue, plasterboard, fabrics, cotton, books, leather, chipboard, furniture, dust, ceiling tiles, and almost any other organic material; So none organic areas like plastic, ceramics, metal, glass, should be scrubbed and cleaned regularly to prevent a layer of dirt (organic material) from forming which will also reduce the potential of mould. Mould spores travel in air inside and out all the time, to reduce the amount of spores will also reduce the chances of getting mould, so vacuum cleaning regularly will remove a lot of spores from furniture carpers, and curtains. Also letting in as much natural light throughout your home during the day will help as mould likes dark places, sunlight kills mould.
