I painted a bedroom 6 months ago.the paint is still slightly tacky to the touch. I have taken a wet paper towel and wiped the wall, and I find paint from the wall has come off onto the towel.
using a dry paper towel renders the same results.the humidity
and temp at time of the painting was 40% and 72deg.
anybody have an idea what is causing this,and what if anything i can do about it.
