Hi, I purchased a new build around 6 months ago and have slowly been working my way around fixing and tidying bits. The builders used Dulux Trade Super Matt on the walls and ceilings and I am struggling in the hallway (where there is alot of natural light) My issue is the ceiling where i have re painted, it looks so patchy and shiny in certain angles or times of the day. I mixed the paint fully, used a roller rather than a brush, applied plenty of paint and didnt push to hard but still it looks pretty bad. Where am I going wrong? I would of thought the paint itself being super matt wouldnt be shiny.....in other rooms its fine its just the darn hallway..... Any help or tips would be great
