Best anti mould paint

[shouldistop]

Any suggestions? Have a real problem with a wall in our bedroom getting mouldy.

You need to find the source of the dampness causing the mould first or you are just patching it over without solving the problem. Leaking gutter, roof issues, drain pipe, etc could be causing it

Agree you need to find the source

When I was younger we just Painted over it and it stopped through everyone and smelt terrible. Paint won't fix it if it just gets damp again.

Could be as simple as needing to centralise and opening the window but don't just paint it till you get rid

I know that's what my husband says. It's mainly behind the bed so I was thinking it might just be poor ventilation? It's a cold, pre-war house and even if the heating was on all day it would struggle to get to 18 degrees.

Following with interest for anti-mould paint recommendations.
I have an under-stairs cupboard that has a mouldy corner. It has a vent in there but it’s cold and dark.

I do open windows and also run a dehumidifier in the morning if it's too cold to open the windows

Re. Anti mould, I like the Dulux easy care bathroom range as it has specific anti mould properties. But as others have said, you really need to find the source and treat it properly.

How would I go about figuring out what's wrong? It's the outside wall.

Yeah try spraying first with anti mould and windows open. If it clears then think about painting

If that doesn't work you've got a problem that needs experts in.

You should be able to get rid of it though. We also had an old house, it's a passion isn't it.

We used something like Polycell 3 in 1 mould killer which you put on and wipe off iirc before painting the wall, Amazon sell it.

Find the source of the moisture, resolve it, paint the offending wall with a rubberised anti-mould paint, then your chosen decorative paint over the top.

Did this in several places in an old tenement flat that had problems with dampness in chimney breasts, overflowing guttering etc. Mould used to reappear once it was dealt with. Rubberised paint stopped that completely.

Could you treat the wall and move the bed away so it can air a bit, perhaps that will help.

Look at the pointing on the bit of wall outside and see if that looks sound or is there a leaky gutter above it, we have had damp before from both these sources.

We have a stubborn spot in our bathroom so used Ronseal anti mould paint. Only issue was it has a slight sheen to it, so had to paint the whole room to make it look ok (it's a top coat, you can't paint over it). We painted it nearly 3 years ago and it's been fine.

We cleaned it with anti mould in September and it came back. Open windows regularly and use dehumidifier.

I'll check the wall and gutter outside. Really hope it's nothing expensive like the roof

Bed is a couple of inches away from the wall. Can't move it anywhere else, we've a huge wardrobe, chest of drawers and dressing table in the room too.

Do you dry washing indoors?

If it’s under the bed and an outside wall it’ll be condensation.

When you say pre war does that mean solid construction?

Our gable end wall used to have a chronic amount of mould which we tackled in two ways:

1. reduce moisture in the house, bought tumble drier and keep windows cracked. Keep hallway door closed when cooking.

2. remove new materials from old solid stone wall, replace with correct material both inside and outside and the wall is drying out.

There were two problems interlaced. The wall itself was holding moisture in the chimneys and had no escape route because of incorrect materials, then because the wall was so wet it was very very cold therefore any moisture in the air would condense.

Now a have few little sachet dehumidifiers under beds and not one spec of mould, phew.

Im a fan of this www.wickes.co.uk/Wickes-Mould-Protect-Emulsion-Paint---White-2-5L/p/122439. We have condensation in our bedroom, this went on really easily. It probably needs a top up paint after a year as we are just starting to get small patches again, but nothing like it was before.

Zinsser paint is amazing stuff. I had a big nasty patch of black mould on my bathroom wall, painted it and it was gone. You can paint/patch over it to match the rest of the wall. I’ve also used it to block the brown wood cupboard coming through when repainting my kitchen.
