Just had an entire 4 bed bungalow replastered - new plasterboard & plaster. The majority is drying out nicely (4 weeks in) and we are hoping to start painting next week. Question - anyone know why the area where the dot & dab was fixed is refusing to dry out? If I paint over that - paint supplier suggesting using tinted supermatt which is breathable - am I going to get problems down the line?
