I recently got the main wall in my downstairs hallway lined to hide a sheen that I had already tried to disguise. I had assumed my failure to do so was because of the paint work left by the previous owner. I stupidly forgot to ask the decorator if I could use vinyl silk paint straight onto the paper (1000 grade). I used silk as this seemed to be recommended for high traffic areas. After 2 coats the wall is still very patchy, as bad as it was before. Is there a simple solution to this, whilst still using silk paint.
