How to Correctly Apply Fiberglass Wallboard Tape

What Materials Do I Need?

To correctly apply fiberglass wallboard tape, you will need the following materials: fiberglass wallboard tape, joint compound, a putty knife, and a utility knife.

Surface Preparation

Before applying the fiberglass wallboard tape, ensure the surface is clean, dry, and free of any dust or debris. Use a utility knife to remove any loose edges or protruding nails.

Applying the Fiberglass Wallboard Tape

Begin by cutting a piece of fiberglass wallboard tape to the desired length. Place the tape over the seam to be covered, ensuring that it is centered and straight. Press the tape firmly onto the joint, smoothing out any wrinkles or air bubbles.

Securing the Tape

Using a putty knife, apply a layer of joint compound over the fiberglass wallboard tape. Ensure to cover the entire length of the tape with a thin, even layer of joint compound. Smooth out any excess compound with the putty knife.

Finishing the Application

Allow the joint compound to dry completely before sanding the surface to a smooth finish. Apply additional coats of joint compound if necessary, sanding between each coat for a flawless result.

Achieving a Professional Finish

To achieve a professional finish, apply a final coat of joint compound over the entire area, feathering the edges to blend with the surrounding surface. Sand the area once more for a seamless look.
