Question

How do you remove MOULD from a painted wall?

Answer 1

knock the wall down

Answer 2

Mould grows where there is moisture so the 'cure' is to prevent the moisture collecting/condensing on walls and creating the environment where mould spores can settle and breed. If its at the bottom of a wall it may be rising damp, because of an ineffective or breached damp proof course, (often flower beds built up outside the wall allow damp to seep in above the damp proof course) In this case, to prevent the mould you need to repair the damp proof course, (expensive), or remove the structure that is allowing the moisture to bypass it. In cooler damp climates like Britain the atmosphere is often laden with moisture and this can be compounded by the moisture produced within the house - from the kitchen, bathroom and given off from the breath and skin of human bodies. The answer here is to increase ventilation, whether through opening windows/ doors, especially after bathing/showering, or have an extractor fan installed. Raising the internal temperature of bathrooms while showering to heat the walls slightly will also prevent the moisture suspended in the air from condensing out when it hits the cooler surface of the wall. But you must then ventilate to remove it from the house.

A bleach solution, (as directed on the bottle), should remove the mould, kill the spores and whiten/lighten the stain. It will recur unless you sort out the ventilation problem, even if you paint over the stain, although some paints have a built in fungicide to discourage mould growth.

Answer 3

You can buy some special stuff which costs about £5 and you dilute it with water. Use a wide paint roller or a soft wide brush on a pole to apply it. It removes all green off painted cement and plastic guttering/clapboard and just about anything else you want to clear. It's not permanent but it lasts for months and it's worth doing and a lot cheaper than repainting walls.

Can't remember what it's called but my better half did our house with it [only for the second time in 3 years] the other day and within 3/4 days all the green had gone!

It would only have come from B&Q or the local hardware shop or decorators supplies.

Answer 4

well, a very effective way to deal with it would include dealing with whatever it is what makes your wall damp....then using a spatula, to get rid of the most of it, then the diluted chlorine, to go a little deeper, and then painting it anew. Will take a little time, and patience...but you will see the results!

Answer 5

you can wash it but it will come back, the wall is abviously damp you will have to treat it with some sort of damp proof paint then paint over that

Answer 6

Try some Sugar Soap

Answer 7

Diluted bleach is the best way - it kills off the spores. Make sure you wear gloves though xx
