Hi. I haven't seen this particular issue discussed nor have I seen the effect before, but this is the first time I used this particular paint (normal Dulux matt emulsion "for walls and ceilings")
I've painted onto new, clean white lining paper (wallrock stuff) and the paint is a mid grey kind of colour. After two coats (fully dry) including all the edging, it looks absolutely ridiculous - every individual stroke is a different shade. Different enough that it looks like a different colour of paint, some parts are much darker and some much lighter, the whole room is a mix of these various shades.
Is there some obvious explanation for this? I used a 4" brush and laid it all off in the same vertical direction, and covered each wall as quickly as I could so it's not that I was dragging sticky paint around into that bad texture you can get. In fact, the texture on these different coloured patches seems to be the same.
Any ideas? I'm going to have to buy some different paint (Wilko durable emulsion is the only paint I actually trust so far, I should have stuck with that) and do the whole lot again, which I rather resent.
