I am drywalling my basement and have begun the arduous task of mudding. I plan on doing the skip trowel finish as I like how it looks and it tends to hide mistakes well. The question I have has to do with the number of coats of mud used. If I plan on basically covering walls with the skip trowel mud, do I still need to mud the seems with the typical three coats? Or can I get by with a decent first coat that covers up any remnants of the taped seems?
