How soon does white gloss paint start yellowing

chickmug

I have painted, two coats, through most of the house over the last six months and see on the odd surface the paint is already starting to look slightly yellow. Is this normal so soon after painting.

Depends on the preparation and the quality of the paint you used.

I use water based satin finish paint as it stays white much longer.

I agree with above. I always use water based satin white paint when i paint woodwork as i like using it and it gives good results. To the best of my knowledge the house i sold three and a half years ago still has lovely white paint work and this was done with wilko water based satin. I always use the primer and undercoat paint first and put enough coats on to give a streak free finish before i put on one or two coats of satin. Thinks it's better for the enviroment too....and it's certainly better for the one using it!!

Hi,

do you smoke, or was there a smoke skin previous, that takes a bit of covering?

It can literally happen in a couple of months. Depends on the prep as previously posted, and if there are smokers, lots of 'oily' cooking going on, etc. Good prep involves painting the knots with 'knotting solution', minimum 2 coats of undercoat & at least 1 top coat.

Water based (or acrylic) gloss does stay whiter longer (much longer), can be recoated in as little as 2 hours. But there are several drawbacks.

• Its not as tough
• It doesn't cover out as well, so more coats are needed
• It is very difficult to get it to stick well to previously oil glossed woodwork. It can sometimes peel off in sheets.
• It isn't anywhere near as glossy as oil gloss, so is often sold as water based satin.

My advice would be if its new wood & previously unpainted then go for an acrylic undercoat & gloss, if it has been oil glossed before then stick to that.

Either way do the best prep possible (always read the tin:D)

Good luck

No smoking and one of the worst affected surfaces I have given three coats so wondering what may have permeated through from underneath?

I tried water based and after three coats still not covered that well I turned to Dulux Once Gloss. All surfaces were old white gloss, in good condition but just needed freshening up, lightly sanded, sugar soap cleaned.

I have been around looking more closely and the main problem is in an inner bathroom with no daylight??

oil based gloss fails under many conditions, as some have said previously...smoking, cooking, etc. But it also yellows much quicker in the absence of natural light & with heat. Not sure why, sometimes its because the oils in the timber leach into it, sometimes because the artificial whiteners in the paint fail.

You can use acrylic water based onto your oil glossed woodwork. I have just never had an acceptable result, usually 'cos the customer bumps the surface & can end up peeling off a large area:eek::mad:. Even when I've done really good prep it still doesn't take well.

An option maybe to use acrylic in the bathroom, any cupboards, or any areas not getting enough light. Or alternatively Crown have just brought out their new formulation oil based gloss & undercoat, called next generation. It is oil based but is supposed to be better in many ways to. I recently got a couple of samples from my trade counter to try, but haven't used them yet so can't say just how good they are.

I use & can recommend the MacPherson or Crown range of paints.

Only non yellowing paint I know is B&Q own - everything else will yellow without fail!!

I have heard that in the absence of uv light, white gloss paint continues to cure over time and this is what makes it go yellow. I have certainly noticed when repainting that the yellowing is worse in dark places such as skirting boards behind furniture.
