Mix the joint compound in a large bucket or mixing tray as directed on the packaging.
Using a 6-inch taping knife, place a good amount of compound on your drywall palette. This should be approximate to an unbaked loaf of dough.
Scoop up an eighth of this amount with a drywall knife and ascend a ladder until you are in comfortable reaching distance to the ceiling.
Spread a smooth coat of joint compound between two panels of drywall, making sure both adjoining pieces get an equal amount of compound. The goal of taping and compounding is to cover every buttressed panel and every corner where the ceiling and wall meet.
Place a strip of drywall tape over the fresh compound, also making sure the tape covers both panels. Cut to size by tearing the tape with your hand or taping knife.
Place another smooth coat of joint compound over the freshly laid tape and continue until every exposed joint is covered.
