Is it true that fill up the joints before taping can prevent cracking?

Best Answer

It can be true depending on a few things. I would use a 20 min setting compound to fill all gaps/cracks/damaged areas. It will set by the time a room is done. Follow up with a tape and longer setting compound. For a DIY 20 min compound also acts as a warm up.
