Dulux Weathershield

[Peter Weilbacher]

Hi all,

last weekend I painted the doors of my shed with the above paint. It was nicely warm, so the paint was dry within 20 minutes or so, and I could see the real color ("nightfall", a great darkish blue). Today, when it was raining, I noticed that the paint was turning light blue, just where it got wet. First only the small under the raindrops, later the doors had turned to a very light blue overall (apart from the top where it is protected from the rain by the small roof). The paint itself was still hard, so my fingers stayed clean when touching the surface. But still this effect is very strange.

Has anyone experienced something like that before?

No, but I'd suggest getting on to Dulux about it to see if your paint was from a faulty batch.

Only once, years ago, with US paint. I used a nice rich dark green paint on kitchen cabinets - whenever they get water spatters, the green turns light, and stays that way for a good half hour. It was not an oil-based paint.

Hmm, Weathershield is acrylic. I think I will follow Peter Johnson's advice and call Dulux. If they have something interesting to say about it I will report here.

I'd be very interested in what you find out. It's been years, now, and my green paint still responds to water the same way.

was this an actual change in colour of the paint, or just a temporary effect of the water on the surface? (i.e. once dry does it go back to how it was).

Finally had time today to call them. After asking me all the questions about how I prepared the existing paint and if I used primer/undercoat they finally decided that they don't know how that could have happened. They promised me to refund the can of paint...

As I spent a whole weekend preparing and painting the doors, I am not going to do it again. And although the refund is nice, it does not help me to to understand the problem and take precautions the next time. ;-)

I can't believe that we're the only people who've noticed this!

Next time, I'll use an oil-based paint. I like the ease of cleanup and the lack of stink with water-based, but I don't like the colour-change.

I didn't redo my green kitchen units. It was too much work to do it again until I absolutely HAVE to.

Q: Which is the XXXX MVP paint someone referred to re long life?

(As in longer life than Trade Weathershield Primer/U-Coat/T/Coat).

Sikkens Rubbol AZ looks nice in white on a pair of high gates, and whilst having the wear resistance of cheese it's easily overcoatable. That said, get it on your hands and it takes a belt sander to get off.

Thanks.
