white gloss paint

[invalid.address]

Hello,

We are about to paint the woodwork with pure brilliant white gloss. We did some painting some months ago with Crown gloss but it went yellow very quickly. We have tried the water based Dulux but like other people have commented here, the finish isn't "right".

What is the best anti-yellowing paint to use?

I did read some old posts which referred to a previous post saying UV light kept white white, but I could not find this original thread; I guess it has long expired off the news servers. I am surprised at that, I would have expected UV to fade, not preserve, the white. Can anyone remember the details of this post?

Someone told me that its because lead has been taken out of paint. Did the lead help stabilise the colour, or have they made that up?

Is it best to take the old paint off all the way back to the wood. that's what I think but SWMBO is impatient and wants to do just a quick sand!

Thanks, Stephen.

I had really good results with Leyland contract white (used with the corresponding primer and undercoat on new wood). No yellowing and hardened (slowly) to a very tough finish.

Stephen,

Firstly a question - are you a smoker? If you are, then that could be the problem.

I have used white gloss over many years and it's something like 2 - 3 years before it begins to noticeably "yellow"

The method I use for RE-painting is thus:

1 - Rub down the woodwork to get rid of flaking paint and any old paint runs.

2 - Wash the woodwork with sugar soap and allow to dry overnight.

4 - Fill and holes and defects as needed.

5 - Two coats of water based acrylic primer/undercoat (externally I would use only separate oil based primers and undercoat) - rubbed down between coats.

6 - And then dependent upon the finish I'm after - one or two coats of oil based gloss.

Using this method gives me a good and long lasting finish.

No, it's not unlike a plastic bag in appearance

This firm used to do a non-yellowing solvent based paint but it was pretty damned expensive IIRC. I heard most of it was sold to London Underground to paint the edges of the platforms, so hard wearing it certainly was

All oil paints yellow. Nature of the beast.

AIUI the yellowing is caused by the oil base going yellow not the pigment. Nowadays Titanium Oxide is used for brilliant whites. The fact that lead is no longer used is A GOOD THING - its lack is not causing your problem.

cheers, Pete.

Yep, that's it. I think the solvent is xylene or something equally awful

Most white gloss in my house - and there is a lot of it - is Green Paints gloss from this bunch:

pleased with it; no perceptible yellowing after 4-5 years. Env-friendly and all.

Not so happy with it used externally though, despite the Which? recommendation. I tend to use Dulux Weathershield, ideally full system from bare wood, and accept that it's going to yellow.

[Brian G]

Yep, but if care is taken in the preparation, you can delay the obvious onset of it.

I've never noticed yellowing on outdoor gloss (we had Weathersheild on our old house).

As was mentioned somewhere it seems to be lack of light that caused increased yellowing - in our old house there were yellower patches on the gloss on the panelling on the stairs where there had been shields of some sort mounted.

Lack of light (UV?) isn't likely to be a problem outdoors.

Sorry for the late reply.

To answer another post's question: there are no smokers in our house. It is only the interior woodwork that we want to refresh and it does seem that it's the shadow-side that is more yellowed. Why does sun light keep whites white?

Merry Christmas
