Most odd.

I've just looked at it and the paint is now virtually dry - it is fast dry stuff. The coverage has worked as I mentioned before and I will sand down tomorrow with some fine and give it a 2nd coat.

The undercoat was exposed to air only in an empty room for about 2 weeks and nothing (except sunlight) has been on it. The weird thing is that the affected area is virtually the whole of a horizontal surface the width of the window and about 4 inch deep. Below it is a much larger surface (actually the base of a window seat) which must be 15 inch deep which is fine. Both sctions were painted @ the same time from the same can ............

I've just had a break to watch Jess Ennis win

More interesting than watching paint dry....

Indeed yes   

Off to have another go now - did about half of one window yesterday so fingers crossed. If I get any more probs then it will be a call to Dulux tomorrow morning. Was bought from B&Q but who keeps receipts that long? It's possible it could have frozen as was in the garage all winter. Fingers crossed - more later.

Are we talking inside or out
As a decorator of about 30 years experience, I have had this happen numerous times. Its normally contamination, and the usual thing is lots of little seperation craters.
Clean down with white spirit and thoroughly dry off. If it repeats, get a small tin of Primer/Sealer, or a B-I-N sealer (Shelac based....be very careful as it sticks like sh1t to a blanket.)
If doing outside...I personally never use water based paints. Although expensive, I have always used Dulux Weathershield, but they have changed the formula of that , and I don't think its as good as it once was.
Oil based paints are imho far better than water based acyllics etc. Water based products allow bleed through of many contaminants, especially nicotine, and yellow much quicker than oil based paints. However, under the right conditions, Acryllics can be a boon for inside undercoating, allowing undercoat and glossing in one day.

I would think the most probable cause of your problem, was the delay in top coating.

Terbert so what your really saying is he to bloody slow

agree with everything you say we only use acrylic as a quick undercoat and as a last resort outside just to get a sealer coat/primer on something also found the gloss generally dries like eggshell

Right, sorted 

I tried a bit more yesterday morning and also on the second window and got the same result  . I suppose there was about 10% of one frame/sash done and 5% of the other. All inside BTW.

So, I bought a new can of Dulux oil based Eggshell & this morning set about doing the job again once the other stuff was dry. The job is now finished and looks good - being oil based it won't be dry until tomorrow - which is fine.

Armed with my 3 cans of Dulux paint (undercoat, quick dry satinwood and eggshell) I called Dulux's technical line to try & understand what had happened. They were very helpful explaining the issue was using the quick dry stuff (water based) on top of a solvent based undercoat - they said it was a no no. The reason it worked with the eggshell perfectly was that it is also solvent based and there is no conflict with the undercoat as there was with the water based quick dry satinwood.

So, a lesson learned.
