Finally figured out why my butt joints kept cracking
For years I had this one spot in my garage that would crack every winter, no matter how careful I was. My buddy Rick came over last week to help me move a fridge and just pointed at it, saying 'Your tape's too tight, man. You're pulling it like a guitar string.' I always thought tighter was better for a smooth finish. He showed me how to lay it with just enough tension to stick, then leave it alone. I redid a small section his way, and after a week with the heat on, it's still perfect. Anyone else have a simple fix they learned way later than they should have?

That makes so much sense. Read something similar in an old woodworking magazine about letting materials move. They said a joint sealed too tight has no room to breathe when the wood or drywall shifts with the seasons. It's like you're setting up a tiny fault line. Your buddy Rick is spot on. A little slack in the tape lets the whole thing flex as a unit instead of fighting itself.

My old foreman used to say you should have just enough mud under the tape to float it, like it's on a little cushion. He called it the "credit card rule" - if you can slide a credit card under the tape before you bed it, you're golden. That tiny gap lets everything move without stressing the joint.
