I am remodleing my old bathroom and making it bigger. In the old portion of our bathroom it had a sprayed on popcorn style celing. I scraped most of it off to put the new ceilg that will be what I have herd called "stomp and drag" with joint compound and paint.I also have went from panneling to drywall. In the old part, where the joint meets the celing it is cracking as the compound dries. Should I start all over with new drywall or just try scraping off the entire celing and redoing it?
