Just bought 2x15L tubs of Wattyl paint from the latest paint mate deal.
Delivered a couple of days ago, and I've left it sitting in the garage (cool, dark, dry) and haven't touched it or moved it since. All up about 48-72 hours. I opened it up today and it looked like this:
The tamper seal is no longer on - I'm assuming it's because they had to remove it to tint the colour to a different white from the base. And the cap was fitted on tightly and correctly (I think). It didn't smell rancid or sour, and smelled like normal paint otherwise.
Is the paint meant to separate this quickly? Did I get a bad batch? How would I rectify this if not?
Yes.
The paint materials have separated.
You need to stir it for a good 5-10 minutes.
