I painted our metal garage door at the weekend using a Crown non-drip gloss. I
prepared the surface well and used a good undercoat. It looks great apart from
rather large round areas towards the bottom of the door that are very dull and
they have condensation on them. If I wash the door down they disappear and the
looks glossy but as soon as that dries the patches re-appear.
Anyone any thoughts on what might be causing this? It was around 14 degrees c
painted bit it did drop down to close to freezing overnight afterwards.
Will I have to sand back and repaint??
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
