White gloss paint

[springbabydays]

Freshly painted white gloss windowsill (dulux). Put a sheet of paper towel on to protect it from a pot plant. In a matter of weeks the patch covered by the paper towel has gone cream!!! Does anyone know why? And is there a way of reversing it or do we have to repaint?

Move the plant pot, and let the sun shine on the cream patch. It should whiten again.
White gloss paint not exposed to sunlight tends to yellow.

Right ok, plant pot has been moved indefinitely! Let's hope there's a bit more sun to come before winter hits.

Thanks for your response, good to know what's happened is normal.

Sorry but it's Dulux. Is it the oil based gloss? They changed the ingredients a few years ago because of EU laws about fumes or something. You need to use water based paint instead which doesn't discolour.
I painted three rooms in my house before i found out why this was happening. My newly painted woodwork is now far yellower than the undecorated bits that haven't been touched for years.
It's worth complaining to the manufacturer, there's stories on the web of people getting the redecoration costs paid for. Wish I had.

I complained to Dulux regarding a painting project in 2011 where I had used their "brilliant white" oil-based gloss. It had yellowed within 2 weeks of finishing! Apparently, Dulux had changed the formula of their oil-based paints due to new EU regulations that came out in 2010 and the new formula yellowed dramatically faster than the previous versio.
I received £100 compensation (to buy replacement paint) but wasn't compensated for the time I had wasted.
I will never use oil-based white paint again, because of the accelerated yellowing. Dulux claims to have fixed it but I remain unconvinced.

Water-based paints used to be inferior to oil-based but they are now much better and the best ones give a very good finish.

My personal favourite is Sikkens Satura Rubbol BL, which gives a lovely silky white satin finish and is also very scratch resistant. I have painted my entire house with the stuff (all the doors, skirtings, bannisters etc).

Other makes I have had recommended to me are Bedec gloss and Johnstone's Aqua gloss. I haven't tried them, but I'm told that they are very good if you want a gloss finish, rather than the satin finish.

Hmm yes- I have noticed this too. We did all of the upstairs doors, and woodwork in Dulux white gloss just over a year ago and it looks dreadful now.

Plan is to use satinwood instead in future, rather than a gloss. I like the look of gloss - it looks 'finished' but not if it's that smoker's yellow.

I'm using satinwood upstairs and am rather pleased with it. Will stick with it for all the woodwork now I think. That's rubbish about the gloss though.
