We've painted new plaster with mist coat (Dulux Trade Supermatt) over a month ago. The mist coat was mixed as per instructions (3 parts paint 1 part water) and applied with a roller/brush. The colour was surprisingly rich for a mist coat but it went on ok.
A month later, when preparing the walls for the next coat, I've noticed that masking tape will fetch the paint off when removed. The masking tape is 3M painter's tape (blue stuff medium tack). Paint doesn't come off when scratched but masking tape just strips it straight off leaving clean plaster behind.
The walls have been thoroughly vacuumed and brushed and plastering was done months ago - it was completely dry. Any ideas what the problem is and what to do next?
