Painting & Decorating Question

Patchy paint on slightly uneven wall

I started decorating a 3 story terraced house and after the second coat of trade matt emulsion the paint on the walls looks very patchy.
The house is only 6 years old so before I started decorating I lightly sanded the walls down and then washed all walls with sugar soap solution.
I am using a roller with hamilton perfection medium pile woven roller sleeves and no nonsense trade matt emulsion (not diluted with water) before I put the expensive paint on.
After examining the patches that appear to be rough I noticed that if I place a flat object against the wall (e.g. a ruler) I can see that the wall is not perfectly straight. There are parts that are slightly uneven by 1 or 2 millimetres. The paint on those - slightly dented -parts is not the same and it looks very patchy and not nice.
As this is the first time I decided to decorate a house I'm not an expert by any means. I need some recommendations as to how can this be remedied.

Use a heavy nap on the roller.. Make sure paint is mixed properly ie add a bit of water.. And put 3/4 coats on.. It might work.. Or get it re skimmed..

Hi Peter. Sometime's when painting an uneven surface the paint may seem to look patchy, this is normally due to the way the light bounces off the wall. If the the wall is very uneven then the chances are the patches would of been visible prior to painting ? and they will probably be rough because when sanding an uneven surface,if not careful bits will get missed. To fix this i would recommend filling the patches or skimming the wall. But i don't recommend applying too many coats of paint now if the wall is not flat. If you have a couple of solid coats of paint on the wall and it's still patchy, don't waste any more paint.
