Best Way to Treat Mould?

ShadyCharacter

Hi everybody,

I recently bought a house which turns out that the seller had painted over a lot of mould to cover it up!

Could anybody give me any advice on the best way to treat mould? And if I wanted to temporarily treat the mould by using a paint stripper (to get the coating that the seller put over it off!!), would scrubbing down with bleach or some other agent to kill it, then painting over the clean walls with an anti-mould paint work well as a solution, even if it is temporary?

Any input and help is much appreciated!

Thanks :beer:

Grenage

Identify the source of moisture (condensation/leaky guttering/et cetera) and remedy.

Use some marigolds and a diluted bleach solution to kill the mould, then paint over.

You must deal with the cause of the mould. This is typically as a result of excess moisture in the home from bathing, showering etc, drying clothes on radiators and cooking. This moisture then condenses on cold walls in poorly ventilated rooms.


Therefore install extractors in bathrooms and kitchens (and use them), keep doors shut to the bathroom, and warm up cold surfaces by insulating.

As above, you have to cure the cause of the mould to get rid of it permanently, but to temporarily remove it I would try wiping the paint with warm water and a microfiber cloth, to see if the paint is water-soluble. If it is, just keep wiping the paint away. You may find that the mould comes away with the paint. If not, HG Mould Spray is very effective.

If the paint is oil-based, you will need a paint stripper to remove it.

as above hg mould spray will get rid of it in 10 minutes, but you need to find out where it's coming from otherwise it'll be back in 3 months.

if the damp is wholly above the damp proof course then it's most certainly penetrating damp.

usually this will be because of broken /blocked guttering, broken gutter downpipe, faulty roof flashing, broken roof tile(s) or exterior brickwork that needs repointing.

if it starts below the damp course you need a new damp course.

As others have said, mould is easily removed with a spray product. Then paint over with stain block.

Make sure the cause isn't something serious such as a leak, then you just need to vent, heat and invest in a dehumidifier.

No drying clothes indoors, keep shower room closed and vent well during/after shower or bath.

I've solved a mould issue with the above.
