B&Q Trade Brilliant White Matt Emulsion

I have been a professional decorator for 15 years and once was a fan of Dulux. I am now asking, what's going on Dulux? Initially my customer had given me some 'special offer' non trade Dulux paint which was so thin I may as well have been painting with milk! I requested they exchange the paint for Dulux Trade and things went from bad to worse. The paint completely dried within 2 minutes making it impossible to keep a wet edge, even cutting when in, the paint was so 'dry', thick ridges were left by the bristles. I will add that all my equipment is the best money can buy and that I pride myself on achieving the best finish possible, my customer now has walls and ceilings that are so blotchy and streaky I'm ashamed to put my name to the job.

B&Q Trade Brilliant White Matt Emulsion worked where 3 to 4 coats of cheaper paints had still left a blotchy finish on a yellowing ceiling. Wish I'd used it in the first place. around £18 for 10l tub.
