white gloss turning yellow

apple eater

What paint or method is used when painting white gloss on woodwork to stop it turning yellow. I have two room doors and a room of skirting boards that have turned creamy / yellow in just a few months.

Anybody overcome this issue and how?

It could be due to the effects of smoking. There is a paint undercoat that seals in nicotine, but I can't recall its name.

Proper undercoat over the wood if its new woodwork? Badly mixed white gloss also tends to discolour if I recall correctly? Modern glosses don't tend to be so bad generally in my experience.

Was it cheap paint?

Mine has done this. It's a lot worse where there is no natural light. I recoated it last year and it's on it's way again.

The woodwork is in a non smoking household. I used dulux white gloss over dulux undercoat. There is no furniture blocking doors and most of the skirting board is unblocked. natural light is in all rooms. I have read that since a new set of legislations came in in 2010 this has been a more common problem but not a real solution or paint/preparing guidance to stop it happening.

Try water based paint its not quite as glossy but it doesnt yellow, dries quicker and doesnt smell for weeks after painting. Throw any Dulux paint you have in the bin its overpriced cheap shit, I have had very good results with Johnstones water based gloss aquawhite.

UV light is the cause - repaint it

There hasn't been any bloody light for the last few months.

Maybe it's just damp.

Its the exact opposite the paint yellows faster when its behind furniture. Its needs the bleaching effect of daylight if it is to have any chance of staying white, it was on BBC Watchdog about a year ago.

depending on what the paint is made from the UV light will break down the dye or brighteners in the paint. same thing happens with paper, ink, and other dyes with UV light.

Its not the colour thats the problem its the base. EU regs mean manufacturers have had to cut down on VOCs for health and environment reasons.

It is turning yellow because it has got malaria. Alt it is drinking too much - effectively the same - liver failure. Main way to avoid this is DO NOT SEND your woodwork to West Africa on holiday or choose a teetotal form of wood. This always works for me.

Just use Satin, or eggshell, you don't have to paint it so much, as the white lasts longer

I worked for Dulux until recently and they had issues with yellowing on their high gloss and brilliant white product. It was made in their Slough plant but due to capacity issues was outsourced to their other facilities and 3rd parties - from memory there were a few issues here. Making gloss paint is quite hard and constant changes to regulations means reformulations are frequent and difficult to replicate

Essentially it's getting harder to make white paint and yellowing is a natural phenomenon - especially when it's dark and warm. I wouldn't agree that Dulux is inferior product - it's a damn site better than own brand stuff

it is something to do with the ingredients in the paint, there was a programme on tv a long time ago about it that the paint gradually became more and more yellow, but only certian ones. it wasn't just one manufacturer either. the main culprits were refunding money for the tins of paint that had been sold and in some cases they were paying for decorators to repaint customers woodwork.

I have a 2 year old new build and the whole house needs doing again. Insides of cupboard doors are the worse. Any tips on what to use, satinwood a mate suggested?

warreng

Yes but Satinwood can have a problem with "grit" in the paint

If you don't paint it white, the white can't turn yellow........that's the trouble with white, it is an absence of colour, so use a colour and it will pretty much stay that colour.

Use water based paint. You dont quite get the same finish as oil based but it is a lot more colour stable

You can buy special non-yellowing white paint (B&Q does some), I've used it and it's great

B&Q used to sell a very good water based gloss and I painted most of my sorting boards with it, unfortunately they stopped selling it, like they tend to do with other very good paints.
