Emulsion paint gone off?!

[screenman]

Water based paint need air to dry in, warm air is best and lots of it, I would put a fan in the room to help move the air around.

Don't think I have one. Heating on now, freezing with the windows open all afternoon!

Amazing...this happened to me on Saturday evening. I'd promised to touch up a wall for a relative with some leftover emulsion ....euggh. it had separated and while the colour came as I stirred it, it was too thin and smelled a bit off. I used it and it needed 2 coats minimum but it was just a touch up.
Never had it before and it wasnt cheap brand paint either...or left outside etc etc. Ah well...in the bin with the rest of it.

Fake news I'm afraid. Biocides are nothing at all to do with VOCs which are Volatile Organic Compounds. Biocides are not banned but they degrade over time and lose effectiveness, especially if the formulation begins to break down after time or freezing in a cold shed.

Possibly. I'm just going by what the chemists at PPG in Birstall told me during training. They referred to EU regulations changing in 2012 which had led to a reformulation of a lot of products, a side-effect of which was increased customer complaints due to bacterial growth in paints which had previously been inhibited. I'm probably getting that mixed in with the VOC regs which changed around the same time.

Bicarbonate..check
White vinegar...check
Prices odour killing candle and matches...check
Heating on...check
Onions...forgotten...tomorrow if needed
Fingers crossed... check

Huh?

Ah the forgotten onion...oops...that would stink too

It does smell somewhat vinegary!

Bowls of salty water with lemon slices in works a treat. Don't use the lemons for your G and T afterwards - it's full of that smell....

vinegar and bicarb? Are you making a rocket?

More likely, more paints being water-based there is greater opportunity for bacteria to thrive as they love a gooey watery environment.

I need some help on the bike...you could try it out too

 

[roadrash]

hows the smell

Still there but I think better. I've had the window open, I've shut it now but have the candle burning. I've flushed the vinegar but the bicarb is still in there

I'm very glad it's the spare room!

I've had that before ... smelled like cat's wee. Took a few days (and open windows) to fade away.

A lot of water-based paints smell. It's due to a change in the chemicals used to make them more environment friendly.

You have to allow time for the paint to dry properly usually about a week.
