I had a quickie wall I had to finish this last week,, Just using regular mud,, The heat and temp was perfect inside the home, so dry time along with other repairs was not a probelm,, was able to finish it out,, tape and coat ready for texture all in one day... Ran thin coat with 6 inch knive along the flats, wipe down with 8 inch knife,, turned around and coated both sides of the butt joints with the 6 , low side with 8inch, waited till the end of the day , coated everything with a ten,, either off set to low side, or down the center,,on the butts,,, next day sand touchup texture, All butt joints layed in flat, except for one that needed alittle more work, since this was a long wall over 25 ft, with window to the side of it, , I hit the bad butt diagonally, from high to low with a ten, only where the mud was needed. turned out great, less work , less sanding, and no joints showing ,,
