How to Use Self Adhesive Fiberglass Drywall Joint Tape

Drywall is one of the most popular construction materials available.

Made from gypsum and water pressed between sheets of heavy paper, this product is used to build walls, ceilings, and architectural specialties. While hanging and finishing drywall is relatively quick, it does require patience and practice to get the job done right. One tool that will help you speed up your drywall projects is self-adhesive drywall tape. The use of this tape shortens the drywall finishing process slightly, as it requires one less coat of joint compound be applied. Any drywall project will benefit from the use of self-adhesive tape.

Hang your drywall as you normally would. Secure the sheets to the studs using drywall screws.

Run a single width of self-adhesive joint tape along each joint where the sheets butt against one another. Apply the tape smoothly and evenly, and try to avoid twisting and bunching.

Apply a single layer of joint compound (spackle) directly over top of the tape using your 6-inch spackle knife. The joint compound should be applied in a very thing layer, around 1/8-inch.

Repeat Step 3 using your 8-inch knife. This coat of spackle will be slightly wider, but should still be very thin.

Repeat Step 3 using your 10-inch knife. On this coat, feather the joint compound away from the tape so that it gets thinner the further you are from the tape.

Wait 24 hours for the walls to dry, then sand the joints lightly until they are smooth and even with the rest of the wall surface.

Things You Will Need

  • Drywall sheets
  • Screw gun
  • Drywall screws
  • Self-adhesive joint tape
  • Joint compound
  • 6", 8", and 10" spackle knives
  • Sandpaper and sanding pole

Tip

  • When hanging drywall in a building with metal studs, hang the sheets vertically. If the building you're working in is constructed with wood studs, however, the sheets should be hung horizontally. Vertical hanging requires fewer cuts, but wooden studs are not secure enough to support this type of drywall application.

Warning

  • Don't apply mud to the joints of your drywall before you apply the tape. This defeats the whole purpose of self-adhesive tape!
