Paint bloom

and the whole door

There wasn't any greasy spots on the door before you sanded it down was there ?

Blooming is caused when excess moisture in the atmosphere at the time of application causes this hazy appearance.

I have never experienced this when brush painting, but when spraying car bodywork. The only solution is to sand all the bloomed paint of and start again, on a warm day!

When I've had this problem on cellulose I've just sprayed more coats over the top. I haven't needed to sand it back first. With cellulose it's moisture in the air that causes it although I've never heard of this happening with domestic gloss paints.

I've had the problem, gloss painting in the evening in September, overnight condensation causing a matt finish.

Just slapped another coat on at a more sensible time of day or in lower-humidity weather.

Well as the paint i was using has a drying time of 16hrs i think i'll leave this now until next spring when the warmer weather kicks in! What an excuse! :-)
