chen08 0 Report post Posted October 15, 2008 Hi, I have seen that some of you here have sealant prior to paint of the wall, which I assume is for the totally new house (unoccupied before). How about for resale house, do I need to have sealant on the wall first prior to painting also? What is the purpose of sealant? I have a plaster box-up in one of my wall. If I do not do general sealant for whole house, would my box-up have sealant prior to painting, as per general contractor quote? Please advise! Thanks a lot Share this post Link to post Share on other sites
