How to Finish Drywall Joints on Doorways

Drywall is a material used in the construction of smooth walls in a home. Drywall comes in sheets that are butted together and screwed into the studs of the framed wall. Drywall seams should be avoided around doorways and windows. Constant slamming of the door and settling of the house around the door make these joints more susceptible to cracking. If possible, hang a long sheet above the door that moves the joint out from the door frame. If all else fails, the proper taping and finishing techniques will prevent cracks.

Instructions

    • 1

      Stir the joint compound with a handheld drill equipped with a mixing paddle until it is uniformly smooth. Pour the compound into a putty tray.

    • 2

      Scoop joint compound onto a 5-inch putty knife. Apply the compound to the joint in one stroke all along the joint. The joint should be covered with a smooth, thin layer of compound.

    • 3

      Cut a length of drywall tape the same size as the joint. Work the tape onto the joint, moving from one end to the other.

    • 4

      Cover the tape with a thin layer of compound and an 8-inch putty knife. Feather out the edges of the compound. Allow the putty to dry overnight.

    • 5

      Sand down the joint the next day with a sanding block or power sander until the joint is smooth.
