Inside Corner Bead vs Paper Tape: Similarities and Differences

Inside Corner Bead

If you do some research, you’ll find that the paper’s tape and inside corner bead are very similar. This article will look at their differences and how they are used.

What is Inside the Corner Bead?

The corner bead is a thin strip of metal that runs along the outside edge of a wall and covers the joint between the wall and the floor. The corner bead can be made from aluminum, steel, or copper. Aluminum is by far the most common choice for building contractors.

The purpose of the corner bead is to hide any gaps or imperfections in the masonry or brickwork at the corners of a room. It also supports tile or other materials that will be installed on top of it. The bead should be long enough to extend past both sides of the corner so that no gaps are visible when you look at it from above.

In addition to protecting against moisture intrusion, it helps prevent cracking due to movement in your home’s foundation over time.

What is the Paper Tape?

Paper tape is a type of paper with a sticky backing. It’s used to seal boxes and envelopes or hold other items together. The paper comes in many colors, but the tape is usually white.

There are two kinds of paper tape: pressure sensitive and non-pressure sensitive. The pressure-sensitive tape has an adhesive backing that will stick to whatever it touches. Non-pressure sensitive tape doesn’t have an adhesive backing and must be applied with glue or double-sided tape before it can be used.

Paper tapes come in various sizes and shapes depending on what they’re being used for. Some common types include:

  • Binding Tapes – these are used for binding documents such as books and magazines, for example;
  • Sealing Tapes – these are used primarily for sealing envelopes but can also be used on other items such as boxes;
  • Double-Sided Tapes – these come in a variety of widths and thicknesses and are extremely strong;
  • Duct Tape – this is very strong, durable tape that was originally designed for use by the military but has become popular with civilians as well

How to Install Corner Bead

Corner bead is available in many different finishes, including galvanized steel, aluminum, and copper. The type chosen depends on the look you want to achieve and how much maintenance it will require.

The installation process is similar regardless of what type you choose. Corner bead can be installed by itself or with other types of flashing material.

1) Clean the area with a wire brush before installing the corner bead.

2) Cut the corner bead with tin snips or a hack saw to fit around any obstacles that may be present at your job site.

3) Hold the corner bead temporarily with masking tape, so it does not slide out of place during installation.

4) Snap it into place using pliers, if needed, then hammer it into position with a rubber mallet until it’s flush against the surface being flashed over.

How to Install Paper Tape

The purpose of paper tape is to mask off areas that you don’t want to get paint on. It’s especially useful when you’re painting a room door, window, or another object that has an intricate shape. You can also use it to cover up edges and seams until they’ve been taped with joint compound.

You can purchase paper tape at most home improvement stores. For the best results, use oil-based painter’s masking tape because it adheres better than latex-based masking tape.

To install paper tape, follow these steps:

1) Tape off all areas you don’t want to be painted. Don’t forget about window frames, doors, and trim around outlets and switches. If you have baseboard heaters or other protruding objects, use a utility knife to cut around them so they don’t get paint on them, either.

2) Apply tape directly onto the surface where you plan to apply your first coat of primer or paint. Make sure there are no wrinkles or creases in the tape before putting it down; wrinkles will leave marks on your final finish coat!

3) Cut off excess paper using a utility knife or scissors so that only 1/85.

4) Lay one piece of paper flat on top of another, with one side facing up and one side facing down so that they meet at the center point

Differences Between Corner Bead and Paper Tape

Inside Corner Bead

The corner bead is made of flexible plastic that can be easily cut and molded to fit around a corner. It’s used with paper tape to create the finished edge on drywall.

Paper tape is a thin strip of paper that has adhesive on one side and is used to cover joints between sheets of drywall. It creates a smooth surface for painting over.

The main difference between corner bead and paper tape is that corner bead is made of plastic, and paper tape is made of paper. Both products are an alternative to joint compound or spackle finishing walls after installation.

If you’re building a wall, you’ll need some type of adhesive to hold the sheets together while they’re being built. The corner bead comes pre-cut in popular sizes so you can use it right out of the box. 

You’ll also need some type of adhesive between each sheet before installing it in place. Paper tape comes in rolls that can be cut into smaller pieces to use what you need and save some for later projects if needed.

Once your walls are up, it’s time for painting! Both products provide a clean finish for paint over without any bumps or imperfections showing through after drying time is complete


Choosing a corner bead product is the way to go if you want to save money and time. You can also learn a lot from doing research on a wide variety of products, as it will help you make your own decisions in the future. Remember that every application requires different materials, so you should always consult with a professional before making your final choice.
