Paint gone yellow behind furniture - why?

[Helena]

I recently had some of my carpets replaced so had to empty a few rooms of their contents and move the furniture around.

When I did this I discovered that a lot of the woodwork (skirting mainly) that had been behind furniture had gone yellow.....this woodwork was only painted a few years previously.

Does anyone know why this would happen? Would a lack of air cause a paint to turn yellow? (I would have thought it would be the other way round) I used Dulux and the right sort of paint so that wasn't the problem.

I guess there is nothing I can do about it but paint the woodwork again, however what can I do to stop this happening again?

hello

I think the oil in the paint will cause all paints to yellow and the lack of light acellerates this process. The allternative is waterbased gloss but it does have it drawbacks.

Thanks so much for the reply. What are the drawbacks with water based paint then?
What would you recommend using?

I don't think water based paints flow out as well as oil , it helps if you use a quality brush such as a perdy , on skirtings and trim this may not be so noticible but for doors you could well see a lot more brush lines .

I personally do not think it is as hard wearing as an oill finish , I guess eventually all oil paints will be phased out but now more than ever customers expect a smooth high gloss finish
