Dulux Gloss Paint Yellowing

[northernchappy]

A number of years ago, I painted the entire interior of the house. Doors, door frames, window ledges, skirting boards.

This was using Dulux Brilliant White oil based gloss. At first, it was brilliant white, but after a number of months, turned into a hideous hew of AGED yellow .
Apparently, EU rules on VOCs , meant that Dulux had overloaded the paint with a drying agent, that resulted in this disaster.
I sanded down then re-painted the whole house again using Crown, but the same result ensued.
Not sure if the dulux underneath the Crown pain caused this.

Anyway, I am fed up of this rotten colour and so before starting yet again,
I also tried another paint at the time, by painting a test area in an inconspicuous place. That paint yellowed too.

Before I start re painting inside the house;
- Should I burn off all the old paint, down to the bare wood, incase the old paint influences the new?
- Could I use water based paint and would it be better than oil based paint?


Before Painting outside;
I will need to paint the wooden soffits outside, as aI prefer them to UPVC.
- Is oil based the only paint I could use? I 'd hate for the outside to yellow like what happened indoors.

A large post so thanks for the effort in reading

I have been a Painter and Decorator for 33 years and have never had a problem with Dulux or Crown oil based yellowing. Are you buying the paints from a proper decorating trade centre and not one of the sheds ie b & q - because even though it says Dulux or Crown on the tin at b & q it is far inferior than trade paint.
Regarding water based paints there are good points low smell, dries quick, but I don’t like it as it shows up all brush marks. I think you should go to a local trade decorating centre, ie Brewers, Crown Decorating Centre or Dulux Decorating Centre and discuss with them are ask to speak to one of Dulux or Crown reps.
Prepped woodwork, 1 coat of trade undercoat and 1 coat of trade gloss should last 4-5 years.

I had the same problem with Crown oil based gloss. Within 2 years it'd turned a off white / yellow. I didn't have the heart to do the lot again so as and when rooms need a freshen up or redecoration I've been redoing it with water based gloss.

Give the old gloss a good rub down with 240 or scotch and clean off. 1 coat of water based undercoat followed 1 coat of water based gloss.

Genuinely stays brilliant white but harder to get a good finish. I cut the tops in with a brush and foam rolled the fronts reduces brush marks.

As far as the outside goes, white oil-based gloss doesn't seem to yellow - it only seems to yellow indoors.

If you did want to go water-based outside, Sadolin Superdec lasts a long time, assuming you sand down first.

Thanks for the replies and the advice everyone! Much appreciated!
Yes gc1967 it was from b&q, and 1 from wilko.

Dulux had huge issues with the VOC changes causing problems for their white oil based paints. They quickly came out with a new formula, which stayed white a lot longer, although that is still somewhat debatable.
The new version was sold with a blue lid at that time (at least in their trade paints). I don't know if it's still marketed that way, as I haven't lived in the UK for almost 5 years, but I would imagine the yellowing issue has been pretty much resolved for most of their white oil based products by now. That said, paint companies are all pushing water based products now, so they may not have put as much into them as I would hope.

As mentioned by sparkwright, the paint won't yellow outside anywhere near as much as it does indoors, if at all, which is due to the ultra violet light it receives. Without UV, white oil based paints have always yellowed badly, which is why skirting boards behind furniture, the inside of cupboards, etc., always appear yellower than the surrounding woodwork.

I can't give much advice on current water based paints available in the UK, but if decent oil based products are still available, I would still recommend using one of those for outside.

As for the interior work, if it's in good shape and it's only the yellowing that is the issue, there is no need to burn it off. You can rub it down, use a good quality high grip stain blocking primer and then apply a few coats of water based gloss.
Don't expect to get a great finish with one coat as water based paints dry quickly and generally require a minimum of two coats to get good, even coverage.
Also, for best results, use a good quality synthetic brush, with moistened bristles, and don't stop painting large areas until you have finished them.

As Misterhelpful says, it is a lack of UV light that causes oil based to yellow. He is also correct that Dulux (and other brands) post 2010 VOC compliance yellowed very quickly. Dulux Trade did release newer "improved formula" tins with blue lids but they are now no longer blue lids. IMO the new paints are finally as colour fast as the pre-2010 paints.

Old coats of gloss. They should not influence the new coats of gloss.

I am not a fan of WB paints. I don't like the way that they flow and they are far less durable but if I have to quote a dark hallway with little natural lighting I do suggest that the client considers them.

Exterior- I use the Dulux Trade oil based Weathershield Gloss.
