[Closed] Eradicating Mould from a wall [Most exciting post of 2021]

There is a corner in our kitchen that, within weeks of scrubbing and applying anti-mould spray, becomes infested again. It is the intersection of two external walls.

I want to re-paint the whole kitchen, and I am wondering if there is a method (or even a product or paint) by which I can keep the black stuff at bay.

Ventilation is generally the answer, though not so easy to do

You get kitchen or even better bathroom paints in limited colours that resist dampness. Have done my bathroom ceiling in it and never had mould grow on it and that has no window in it for ventilation (just fan)

Might sound daft but check for something running into the wall from outside.

We had a damp patch behind our fridge for ages, could never figure out why and nor why we could never successfully treat it. Then when renovating the house I discovered an old TV aerial cable that was run from the chimney, down the gable end and into the house behind a window frame. Had been cut at both ends and the bit inside the house hidden away. Over the years the wires had corroded away so we were effectively left with a hollow tube that channeled rain from outside to behind a skirting board, which then ran along the kitchen floor tiles to the lowest point - behind the fridge.

Ventilation and insulation if possible, if not then this

Exterior Masonry paint used internally is quite good at keeping mould at bay, you can get most colours mixed

We get a bit of mould on the bathroom wall even on top of bathroom paint. The advantge with bathroom paint is everything just wipes off easily, as the surface is like wax. The underlying problem is a solid 9" wall and a lot of moisture from the shower. We leave the window open most days as well...

I'm pretty sure that once the spores start, no amount of cleaning will really do much, it just keeps going.

Wee yins room was pretty bad, but chimney needed venting, along with treating the outside wall pretty much as that video, and 2 years later it's good. I still don't put any furniture on said wall though, not a chance.

We use Flash bleach spray, which on top off waxy bathroom paint pretty much eliminates it for a few weeks. Don't get any in summer, just winter.

We got a couple of cold walls. Atmospheric moisture condenses on it. Zip all chance of eliminating the stuff permanently. Unless that part of the house was rebuilt with actual insulation.

As above, furniture stays away from those walls and they need regular cleaning.

You can remove the mold by using the vinegar or diluted bleach. Apply them on your walls or ceilings, leave them for more than one hour and then wipe the walls with a wet cloth. Finally, keep the bathroom ventilated to make the ceiling dry as soon as possible or that the mold will come back soon. To prevent the mold from growing again and again, you may have to choose the best paint for your steamy bathroom.

we've had mould in kitchen, bathroom and bedrooms before. we had textured ceilings, so replaced for smooth plaster, a good extractor and dehumidifier and we dont get any now.

if you do have any texture, the spores are harder to clean, so thats a consideration if it applies to your room.

EDIT: and yes, that HG mould spray is excellent.

HG mould spray is excellent but again I'd be looking to stop the issues. I get the occasional mould spot, as the external wall bricks have become porous, and so treat the external wall with Thompsons Water seal (clear) every couple of years. Seems to work

Get a humidity reader and dehumidifier off Amazon. At least you can measure the problem, but as said above, fix the cause of condensation (easier said than done though).

The solution to mould is normally background heat and ventilation. If you've got an old house then porous materials help (lime plaster and breathable paint).

As said above, check for sources of damp/ water penetration.

The foil wall paper stuff can keep it at bay for a while (but the mould usually pokes its head over the top eventually!)
