Does Oil based paint really discolour over time?

johneym

hello folks,

its a toss between dulux satin wood oil base or colortrend waterbased satin for my doors. The colour will be an off white.
I normally prefer oil based paints as the finish is better etc, but I am hearing stories that now due to less voc it turns yellow. Is this fact or fiction and are we talking over a period of months or years? All my doors will be exposed to lots of natural daylight, if that makes a difference.

Many thanks

White oil based paint will discolour. It goes yellowish.

Also, if you're doing a few doors the oil based paint will be quite strong smell-wise, and it takes ages to dry, whereas the waterbased is not smelly and dries very quickly.

It will go yellowish after about 10 years or so unless you have a smoker in the house.

gentlemen, many thanks for the replies. Not worried about smell,house empty anyway, its the finish thats important.
sleeper thats great about the 10 years and if I got that i am more than happy, but where did you get the figure? These reduced voc levels are on the market since 2012 only. Somebody posted here a while back that after a few months the paintwork in her hall turned yellow??

I don't know the science of it but if I remember correctly it goes yellow due to lack of sunlight. I could be totally wrong but it sticks in my mind because it's the opposite of what you would expect

Best to paint it yellow, then no worries!

It could go yellow within a year, I've seen it happen very recently in a house that was only painted just over a year ago.

I too will be doing this soon.

Sleeper, I would love to know where you got the 10 year figure?

I had a property maintenance company. We had tradesmen for different jobs. We worked for landlords, homeowners, estate agents etc. We kept logs on different properties. We'd usually paint walls every 3 to 5 years. 10 years was the average for white gloss paint. I wouldn't be expecting long out of store brand paint, Woodies, B&Q etc. Spend the extra on good paint, give it enough coats of undercoat & gloss & you should get years out of it

seams to conflicting views.
I too used to happily gloss years ago sleeper, but apparently the oil paint nowadays is crap. They have taken out the lead, solvents and most of the dangerous chemicals, which leaves a crap paint.
I would still be willing to use it for nostalgia sake but dont want to end up with a yellow house a few months from now. Wife would kill me(I asked her if I could paint everything yellow but she was not impressed)

There maybe a little confusion. I said it would go yellow around the 10 year mark. It will loose the brilliant white look much quicker than that. There are usually a few painters on here that can give a better reply. It's something they'd be using everyday

What is on door at present? Is it Oil based or water based or are they new?

If its oil based then stick with oil based, if its new then I would say go water based, stick with satin as finger prints can show up much more on a glossed finish.

The reason why paint yellows over a time is due to heat, if you paint a radiator with just normal oil based paints it will yellow very quickly.

Water based finishes tend to be less hard wearing than oil based finishes...

But water based finishes are not prone to yellow and can dry very quickly making touching up easy enough.

thanks for replies,

very old teak doors . I have already put primer on them.

I found Colortrend satinwood water based very good for my doors.
