I'm doing some drywall in my basement. I've got the first coat of mud and tape on and ready for a sand. I used a General purpose Joint compound for this coat. Someone suggesting I change to a "Light duty" compound for subsequent coats. Drying time is not really an issue so is there another benefit to buying a whole new bucket of a different kind? Will I get a better result? Or do i Just go ahead and use the plenty of extra I have of th GP?
Thanks.
