Why is my Gloss Turning Yellow

markdavey

Hi,

I have recently decorated a new extension which includes a new downstairs cloakroom. The gloss in the cloakroom has already turned a distinct yellow colour.

I used Dulux Professional Undercoat and Gloss and did 2 coats of undercoat and 1 coat of gloss as I have done in the rest of the extension.

Only this room has turned yellow. The room has no windows and only an extractor fan.

Any ideas as it already looks like has not been decorated for years...

Very strange are you sure it is not just the light in there?

Nope, I have brilliant white walls and against this, the Gloss is Yellow.

i think there is another thread regarding Dulux turning yellow. Try a search.

It sounds like you gloss seems to have aged prematurely, I wonder if you inadvertently purchased an old / dodgy batch of paint. It may be worth contacting the manufacturers with details of the batch no if you still have the tin.

I personally stay away from gloss - I think it looks nasty and prefer to go with an eggshell / silk finish for skirting boards etc.

The dulux 2010 compliant gloss does yellow fast and dulux are aware of it as a memo was sent round to all there ddc shops,saying they no theres a problem with paint discolouring and will not be held liable for it.

It is a serious problem and most if not all manufacturers have had problems. They had to change the formulation of oil based paint to comply with European regulations, and yellowing is the result. It was particularly bad a year or so ago. My ex boss had his whole house redecorated at Dulux's expense after his new Dulux paintwork went brown. In a recent email Dulux customer services told me that they had fixed the problems. However, about a month ago I painted a loft door with white gloss, purchased not long before, a tin with a blue top, and when viewed next to a white satin architrave, it is off white, a sort of cream colour. So I do not beleive them. Non gloss oil based paint is said to be more resistant to yellowing. Some painters are trying water based paints.

Lack of windows can be a problem. I once had a white gloss bedroom door, which took a yellow patch behind where our dressing gowns hung. Left them off for a few days and the paint went brilliant white again.

Dulux have already had to pay out compensation for their Dulux weathershild gloss forming black streaks on the surface so I think the new regulations are causing major problems for paint companies......

I have had this problem with Leyland paint too just a plain white bathroom shelf painted went yellow painted in August 2010. I tend to now use water based paint it keeps its colour. I think its down to less harmful chemicals they put in paint probably down to some Euro policy at a guess

Following changes in Volatile Organic Compound (VOC) legislation, paint manufacturers have been required to reduce the amount of solvent in traditional trim products.


As part of this process, many solvent-based coatings were reformulated to have a higher 'solids' content.

While these are better for the environment, the new formulations can discolour more quickly.
This results in greater yellowing appearing on the paint surface in all conditions.
Also, in environments with limited or no daylight, and higher temperatures the paints are prone to yellowing even faster.

Unfortunately, this discolouration is a challenge faced by all manufacturers and brands with solvent-based paints.
