We have a VM house with a front porch. The paint is peeling from the ceiling and a painter told me this was because it was done incorrectly in the first place. The builder used wallboard which should never be used outside. He claims that it will never hold paint well and won't guarantee his work if he paints it. He suggested putting up MTO (?) or some other covering to solve this problem. The house is 5 yrs old so I doubt VM will help. Has anyone had this problem or know about it and have any advice? Thanks!
