When it comes to construction and renovation, achieving smooth, professional-looking seams is crucial. Drywall tape plays a key role in ensuring those seams are flawless, providing stability and preventing cracks. Whether you’re working on new construction or patching up a hole, knowing how to properly install drywall tape can make all the difference.
Understanding the Types of Drywall Tape
Before diving into the installation process, it’s important to understand the different types of drywall tape available. Each type serves a different purpose and may be better suited to specific types of projects.
Paper Tape: This is the most traditional form of drywall tape. It is non-adhesive and typically applied after being wetted. Paper tape is known for its strength, making it ideal for inside corners where two walls meet.
Mesh Tape: Made from fiberglass, mesh tape comes with an adhesive backing and does not require wetting before application. It’s ideal for patching holes and creating a durable, flexible seam that resists cracking.
When you’re installing drywall tape, there are two primary methods to consider: wet application and dry application. The difference lies in how the tape is prepared before being applied to the drywall seam.
Wet Drywall Tape Application
This method is typically used with paper tape. Before applying the tape, it’s moistened with water, which helps soften the tape and make it more flexible. Wetting the tape improves its adhesion to the drywall surface and makes it easier to embed into the joint compound (also known as mud). Contractors often use this method for larger projects because it provides a strong bond, especially for inside corners where walls meet.
Dry Drywall Tape Application
Dry applications are commonly used with mesh tape, which comes with an adhesive backing. This type of tape does not need to be wet before use. It’s applied directly to the drywall surface, sticking in place without additional preparation. Dry mesh tape is often used for quick repairs, like patching holes in drywall, because it’s faster and easier to handle. However, because it isn’t as flexible as wet-applied tape, it’s better suited for flat surfaces rather than corners.
How to Install Drywall Tape
Whether you’re using paper tape with a wet application or mesh tape with a dry application, the overall process for installing drywall tape is similar. Here’s a step-by-step guide that covers both types.
Prepare the Area: Ensure the drywall seam or hole is clean and free of debris. For damaged areas, cut away any loose drywall before starting. We also recommend using a drop cloth or kraft paper to catch any drywall dust.
Apply the First Layer of Compound or Spackle: Spread a thin, even layer of joint compound (or spackle) over the seam or hole. This step is the same for both wet and dry applications.
Prepare the Tape:
For Paper Tape (Wet Application): Lightly moisten the paper tape by dipping it in water or using a damp sponge.
For Mesh Tape (Dry Application): Skip the wetting step and simply peel off the adhesive backing.
Place the Tape:
For Paper Tape: Press the moistened paper tape directly onto the seam, embedding it into the joint compound.
For Mesh Tape: Stick the self-adhesive mesh tape directly over the seam or hole.
Smooth the Tape: Gently press and smooth the tape into the joint compound. Ensure there are no bubbles or wrinkles. For mesh tape, make sure the compound is pressed through the mesh.
Apply a Second Layer of Compound: Spread and smooth a second, thin layer of joint compound or spackle over the tape
Let It Dry and Sand: Allow the compound to dry completely, then sand the area lightly to create a smooth finish. Apply additional coats if necessary, letting each layer dry before sanding.
