Bought 2.5 ltr white gloss to use for painting exterior windows. Was fine for that, used about 1/6th of tin. Tin then closed for 9 months and kept indoors. On opening to use again found a thin skin on the paint. Tried to stir the paint found it was like water and no thickness or sediment at bottom of the tin. Trying to apply it was very difficult running off the brush and on the wood work so difficult to get coverage and no brush marks or covering underlying marks. Would like to know whether anyone else has had this experience. George Seymour

I couldn't agree more-this paint was a nightmare. It seemed to go on okay for the first coat (I washed down and sanded the door before painting) but did also have some "sags" in the paint. When I went to put on the second coat the next day I found it had cracked in many places and looks awful. Now I have to have someone come and fix the job. Fortunately, the paint was part of a 3 for 2 offer so didn't cost me anything but I will now have to pay to have it fixed.

Within the first few minutes I could tell this was going to be a bad job. It was like painting with treacle, and not enough pigment in the paint. I've ended up with a blotchy door, and despite using correct techniques, have ended up with 'sags' of paint. I'm going to rub the door down again and re-do with some decent gloss!!

This is quite possibly the worst paint I have ever used. It is very thick, and unlike normal paint, it does not become less viscous with brushing. Using proper technique and finishing strokes etc just results in drag, visible brush marks etc. Because you can't spread the paint correctly it runs and drips all over the place

It is a very flexible product, and remains so in the long-term. This means it is very hard to sand down when you lose your patience with it and want to paint over it with Dulux Trade Weathershield, which I would strongly recommend.
