Er...dunno. I assumed (perhaps naively) that if paint is vinyl-based it will say so on the tin. The trade version was def. vinyl - it peeled off in a big chunk in one area where the wall had not been properly mist-coated!

I think it has got vinyl in it.

I wonder if it was formulated for daylight or artificial light, cause the one time I put it on (never bothered with it after that) it made little or no difference under daylight, yet when the lights were put on, it seemed to be a bit better. Mind, if you didn't know that it was Light & Space, you'd just have thought it was Matt Vinyl.

It's one of Dulux's poorer attempts at kidology IMO.

I agree, but customer had great faith in it.

Perhaps it's like the placebo effect in medicine!

Dulux is to paint what Heinz is to beans, most people will demand it because of the name, (must be good it's dulux innit) the average diyer will not notice the difference between a good paint and a really good paint as they don't use it that often. Dulux will unleash all the fads onto joe public and try and keep trade paints at a consistently good quality (until recently )

Dulux once etc is the equivalant of a microwave meal, proper prep, undercoat and topcoat is the traditionaly prepared dinner. In this day and age people will sacrifice quality for speed and ease of use. Just the way it is .....
