5 year update: Water-based gloss paint stays white longer

jap200

I've just spent ages hunting for an old thead that I started 5 years ago!

I am linking to it here in case its of use to anyone else. Basically I had emailed Dulux and Crown to ask which white paint for woodwork stays white the longest (i.e. avoids yellowing). I now need to repaint those same areas and couldn't remember the answer and had deleted the old emails, so here it is:

Can't believe it's 5 years since I painted those 11 doors, but that now explains why they don't look so good!
However, the ones I did with water-based paint are still white (apart from the knocks and marks of course), whereas the single one I did with oil-based satin (before getting the answers to my emails) is really yellow in comparison, which looks awful against the bright white frame.

So I can definitely confirm that the water-based paints (although more drippy) stayed bright white for 5 years and the oil-based paint did not.

Dulux told me that they had never had an instance of Sikkens Satura oil based paint going yellow. Take that as you wish, as they also told me they had fixed the premature yellowing of normal oil based paint, and they hadn't.

Sometimes how much daylight an area gets can affect the yellowing, I've used various paints on a door and skirting in my dark dining room and they've all yellowed to some extent. Whereas oil based satinwood in bright living room has remained perfectly white and only needed to be repainted when decorating.

I did my doors and boxing round the pipes in Dulux Professional Gloss 12 months ago in my downstairs cloakroom. There is no natural light in that room and the Gloss was VERY yellow in less than 3 months.

I am resisting but the wife wants it done again

Same here but I think I used a Crown one coat solvent based paint.:mad: .

Noticed on my last visit they are now selling some form of bright white water based that I might try..

Was it the blue tin lid? I used some of that on a loft door, and within months it was cream. It contrasts sharply with the Sikkens paint on the adjacent architrave.

Yep, the very same:

Water based Satinwood FTW

Yes it seems that light does affect the outcome. This is the answer that Dulux gave me to my email 5 years ago:

"All oil-based paints are prone to yellowing, but this is accelerated
when they are excluded from direct daylight or subjected to higher
temperatures. This is why gloss on radiators yellows faster than gloss
on skirting boards, for example. If a new carpet has been laid recent to
the application of the gloss, the ammonia found in carpet underlay can
cause the yellowing to accelerate.

At present there is no means of eliminating yellowing from decorative
oil-based paints, though better ventilation and more daylight will help
them keep their colour for longer.

The best alternative is to use a waterborne acrylic gloss paint such as
Dulux Quick Drying Gloss or Quick Drying Satinwood. Water based paints
have excellent anti-yellowing properties, are very low odour and dry
much faster than solvent based paints."

Rate 2/5 on the B&Q website.

Read somewhere it was due to EU regulations that had forced them to reduce volatile organic compounds in oil based paints that has caused the yellowing problem.

I do usually associate higher solvent content with a smoother glossy finish, so have gone for higher solvent content where possible in the past. Any comments on how the water based gloss paints compare on levelling and smoothness of the final finish?
