Mould

We have found that despite our best efforts, we have been plagued with mould on our walls this winter. It hasn't been cold in our house and we have kept it well ventilated, so I don't know what we should have been doing. I have scrubbed the walls clean and re-painted, but it has insisted on coming back. Does anyone know of a product I can get here to get rid of it?

Cheers

Mild bleach solution will get rid of it. Wear gloves .... Marigold's will do . . . . if she doesn't mind!

Hi Summer

You can certainly buy 'anti mould' paint in the UK

eg

Why not try the local equivalent of B&Q. It's probably more of a problem in Portugal than the UK, so they should have something

If the mould keeps coming back then it is likely that you have a humidity infiltration somewhere around the area where it develops. Before you spend a load of money on redecorating, I would suggest you have somebody check the structure's exterior for damage.

Typical problem areas are cracks in the rendering, a flat roof/old insulation, poorly insulated drainage pipes.

Summer,
It is very common out here and this year of course has been damp.
Most buildings at sometime or another unless very lucky, suffer from this annoying problem. One of the reasons is that the buildings do not have air bricks.
Ok.....dry day so you can have the doors and windows open, protection for eyes and skin, old clothes, rubber clothes and neat bleach on the areas containing the mould...let it dry. Next time you paint...there is a paint containing anti-mould but we believe that it is not full proof.
Many also use humidifiers, but then as soon as you open an exterior door you are letting in cold and damp air again.
Regards.

go along to cin paints in lagoa (opp fatacil) they sell an anti fungis solution which you need to spray on the walls...bleach will remove the mould but not kill it..if your in doubt about any products ask to speak to howard (english) from "Homes" in lagoa near mestre maco he will advise you on paints will anti fungis chemical and is very clued up on such matters
...best as well to keep de humidifier running as much as possible

A de humidifier run twice a week for about 6 hours should do it. It's the dampness that gets inside the walls causing the problem. They are not expensive, good luck. Charlton for the cup!!!

You know the main problem which has already been mentioned is that modern construction here just doen't "breathe". You get a concrete and cement box often topped with a concrete slab "lid" and there is nowhere for the condensation to escape. If you notice, the older houses with roofs made of timber or even concrete beams and with a roof void don't suffer from this problem. Frequent airing is the best answer I think.
