Anyone a paint expert?
My house was built 11 years ago. Over the years I've noticed that when I run my finger down the white mullions of the windows and the trim of the house, my finger is covered with a powdery or chalky substance. It's impossible to wash my windows without the white stuff dripping over the windows. It's as if you wet crushed chalk. Would anyone know what kind of paint would cause this? Did the painters use bad paint? TIA.
