My old boss in Denver said to always mud the whole seam before taping, but that just made a huge mess.
He insisted it gave a better bond, but on a big job in Cheyenne, the mud kept squeezing out and I had to scrape it all off. Now I just put a thin line down the center and it's way cleaner. Does anyone else have a strong opinion on this method?
Tried that full seam method once and it was a disaster. The tape just floated on all that mud and left a giant ridge. A thin bead down the middle gives you way more control and less cleanup.
