How to Use Tape on the Walls

Remodeling projects involving drywall include the use of drywall tape. Drywall tape covers seams between the individual sheets of drywall. The paper tape has no adhesive of its own, but is held in place with layers of drywall joint compound. The tape has a coarse surface that provides maximum adhesion to the joint compound. When applied correctly, the tape helps create a smooth, seamless wall surface that is ready for paint or wallpaper. Drywall taping requires the proper tools, materials and basic home remodeling experience.

Drywall joint compound
Paper joint tape
5-inch broad knife
8-inch broad knife

Instructions

- 1
  Measure the distance of the drywall seam from end to end or top to bottom with a measuring tape. Cut the required length of paper drywall tape with scissors
- 2
  Apply a layer of joint compound approximately 1/8 inch thick over the seam between two installed sheets of drywall with a 5-inch broad knife. The joined seams on the outside edge of each sheet are recessed for this purpose.
- 3
  Place the paper drywall tape into the joint compound with the raised center seam against the drywall. Run the broad knife along the length of the tape, pressing it just hard enough to cause the base layer of compound to ooze out from under the tape.
- 4
  Remove any trapped air or lumpy areas beneath the tape by drawing the broad knife smoothly and slowly along the seam joint. Allow the first coat to dry according to the compound manufacturer's recommendation.
- 5
  Apply two or more additional coats of joint compound over the tape, feathering the compound outward each time with a wider, 8-inch broad knife. Allow drying time between coats.
