Accidentally Used Topping Compound for Taping Drywall Joint. What To Do?
Topping compound is softer and easier to sand than regular mud. If everything is dry and and secure you may be ok. If you want to remove it just get it wet and topping mud should release and can be scraped off. If you haven't done very many joints I would remove it because it is not as strong. If everything looks go ahead and top and sand with topping mud.
