It is possible to get compenation from Dulux.

I made some curved windows for an Oast house and the Dulux admitted after many complaints that they had issues with the Weathershild forming grey streaks and they paid out for the Labour and materials to decorate the windows a 2nd time.There were 27 windows in total so it was not cheap.

People shouldn't give up, be like a dog with a bone and just about every decorator I know have had problems with Dulux.That said Weathershield is a good system when it works, along with Sadolin Superdec

I can see no excuse for yellowing occuring under ornaments on a window sill...

This is not a new phenomenon. Oil based gloss paint has done this for years - its because its been deprived of natural lught under the ornaments or flower pots or whatever. The EU has a lot to answer for with recent issues with spirit based paint (actually and some water based too for that matter) due to their stringent VOC compliance requirements introduced to satisfy the sacred cow of global warming. Hoiwever if Duklux, or whomever, still market the stuff poost 2010 as Pure Brilliant White thats what it ought to be. A name change to "various shades of mud" might just be a simpler solution.

it may be a good time to switch to water based alternatives, i've found over the last 2-3 years w/b paints have come on a great deal . you do not get the brilliant mirror shine of solvent based paints but w/b does stay much whiter , plus it's a lot easier to apply , doesn't smell as bad and dried quickly .
i have been using bedec multi surface paints for 4-5 years , a job i did a couple of weeks ago was a redec of some windows that had been stained with sadolins previously . the bedec i put on 5 years ago was still in excellent condition apart from the sills which i had filled with plastic wood where they had dried out in their sadolins years , as they face due south they had been well and truly roasted , but the msp perfomed really well . another good paint is dulux w/b satinwood - a good alternative to gloss

Totally agree. I bought water-based paint a couple of years ago by accident and it was like trying to cover the wood using milk.
Won't be rushing back to try again.

what you needed was a blanking primer such as zinsser bin primer follwed by a couple of undercoats and then a coat of gloss

Agree wholeheartedly. 12 stained (very dark) interior doors treated exactly this way last year and they are fine today.

Agreed. Zinsser B.I.N or Zinsser 1.2.3 are the business.

It's quite hard to get hold of and costs more than rivals, but it's worth it. Try their UK website for retailers. A 1 litre can cost me £12.

Depends where you live. In the south Cane Adam have BIN in stock. They are owned by the same people as Brewers, so they might also stock it.

Incidentally, there are at least two kinds of water based wood paint, namely acrylic and polyurethane. Dulux quick dry is acrylic whilst Sikkens BL and Ronseal Diamond are polyurethane. The latter are thicker, and cover better. I am told that adding Floetrol will help get a better finish, and a good synthetic brush helps too. It might be worth trying a tin of each. I thought the Dulux was poor, very thin.
