why does gloss paint go yellow?
hi i would like to use satin or eggshell white paint on gloss painted doors as i find white gloss paint goes yellow and satin seems to keep white, is it because there is oil in gloss and need to clean brushes in spirit and the new satin paints seem to clean in water, can someone advise me on this. thanks, chrissy:)

what brand of paint? Seems like your problem is cheap paint.

gloss paint or satin
:eek:i think it was a leyland paint or possibly focus own brand. also the doors are on the upper landing which is quite dark although im not sure if this is relevant. i do prefer satin paint myself although i know someone who actually uses silk emulsion. whether this is any good, i do not know and have never tried it. thanks, chrissy

typically, white oil based paint will yellow more quickly and more noticeably than a latex - regardless of sheen level. If you use a quality gloss latex white you should see a big improvement. I've found that over time, every oil based white will yellow to some extent - even the ones that are called "non yellowing white" =). If you are going over gloss just use a good bonding primer like 1-2-3, fresh start, aqua lock, etc.. then topcoat with a quality latex that is made for cabinets - BM Water based satin impervo is good, cabinent coat is another, if you want gloss use ben moores 309 high gloss latex line...

good luck

Oil based paints will yellow, latex paint will not.

Oils yellow even worse in areas that get little sunlight. Everything points to a change to a high quality acrylic to fix this.

I would say check out for the ICI lineup which is suppose to be very good in the UK. Unfortunately, in classic ICI style, the website is a massive cluster of product information with little or no means of finding the correct product without being very familiar with what they have to offer. Maybe just visit a Dulux store.

True, and it's also true that the glossier the paint finish, the more binder (some call it 'resin') the paint film has. On the other hand, the flatter the paint, the less binder it has... and the most pigment too, in general.

Now oil - or 'alkyd' - based paints have another problem. The resins used in oil-based paints are partly based on vegetable oils that can become rancid and turn yellow with time. They oxidise in reaction with air; this is good because the oxidised layer is tough and durable - but you have to hide the yellowing.

Therefore, the glossier the oil-based paint, the more it will yellow.

You don't have those problems with latex (or water-based) paints.
