Second coat of shed paint 'splitting'

Wife bought a shed a few weeks ago, and is setting about making it
look 'pretty' with a sage paint. On recommendations here we got
cuprinol shades which went on beautifully on the first coat.
However the second coat seems to be separating when being applied -
almost as if there's some contaminant like white spirit which helps
it to split a few seconds after it has been applied.
She hasn't used anything other than water to clean the brushes and
the shed isn't in direct sunlight.
Any experience of this; is it normal?
Cheers!

Yes, that's the sort of effect. I've actually just taken time to read their website about the second coat and it says "Cuprinol Garden Shades will be touch dry in 1 hour under normal weather conditions. Where a second coat is required, allow up to 8 hours in between coats." Unfortunately she couldn't get the second coat on within 8 hours due to weather / kids etc, and I suspect she's mis-read it as "allow up to 8 hours for drying before applying second coat". It would be helpful if it said "it is essential that the second coat is applied within 8 hours" as she might have done fewer panels with 2 coats instead of the whole shed with 1 coat.
We'll just have to put up with it looking odd when it is applied, and hopefully it will dry out just fine anyway..
Thanks!

If I'd been doing this myself, it would *definitely* have been more than
8 hours before I applied a second coat, i.e. before I could bring
myself to start painting again!

Hmmm -- personally I'd have read their instructions as meaning "you may

It is possible that the shed still contained moisture, this
happened to my new shed, I had to wait a few weeks for the wood to
completely dry-out before attempting painting. Even with a water
based treatment it can still lift the new paint when dry as the
wood starts to emit moisture.

I had no trouble with a second of paint on my shed using the same paint and
even the same colour but mine was not new and previously been painted with
old engine oil ('cos I was skint and that came free!)
So I think Stephen must be right. He obviously knows more about paint than
me of course there are other amongst us who know everything!
