There are many different ways to tape drywall corners, but the most important thing is to get a tight seal so that the joint compound doesn’t seep through. In this blog post, we will show you how to tape drywall corners step-by-step so that you can get a perfect seal every time. 

What You’ll Need

In order to tape drywall corners, you will need the following materials:

-Drywall joint compound

-Drywall tape

-A putty knife or taping knife


First, cut a piece of drywall tape to the desired length. Next, apply a generous amount of joint compound to one side of the drywall tape. Then, use your putty knife or taping knife to press the tape into place on the corner of the drywall. Finally, apply another layer of joint compound over top of the tape. Allow the compound to dry completely before painting or sanding.

Step One: Prep the Area

Before you start taping drywall corners, it’s important to prep the area. This means making sure the wall is clean and free of any debris or dirt. You’ll also want to make sure the wall is dry, as this will help the tape adhere better. Once you’ve prepped the area, you’re ready to start taping!

Step Two: Apply the Tape

Applying the tape to drywall corners is a relatively easy process, but there are a few things you need to keep in mind in order to do it correctly. First, make sure that the surface you’re applying the tape to is clean and free of any debris. If there’s any dirt or grime on the surface, it can prevent the tape from adhering properly.

Next, cut the tape to the desired length using a sharp knife or scissors. It’s important to make sure that the pieces of tape are all roughly the same size; otherwise, they won’t adhere evenly to the surface. Read more about Drywall Taping here.

Once you have your pieces of tape cut to size, it’s time to apply them to the drywall corner. Start by peeling off a small section of the backing and attaching one end of the tape to the wall. Then slowly peel away more of the backing as you press the rest of the tape into place. Make sure that you smooth out any bubbles or wrinkles as you go; otherwise, they’ll show up once the paint dries.

Finally, once all of the tape is in place, use your knife or scissors to trim off any excess. And that’s it! You’ve successfully taped your drywall corners and are now one step closer to finishing your project.

Step Three: Finish Up

After you’ve applied the first layer of drywall tape and mud to your corner, it’s time to apply the second layer. This time, use a wider piece of tape (about 2″ wide) and apply it directly over the first layer of tape, making sure to smooth it out as you go. Once again, use just enough mud to cover the tape and fill in any gaps. Allow this second layer to dry completely before moving on to the next step.

Drywall Tips and Tricks

When it comes to taping drywall corners, there are a few things you need to keep in mind. First, make sure you use the right type of tape. There are two main types of tape: paper and mesh. Paper tape is cheaper and easier to find, but it’s also more likely to cause problems later on. Mesh tape is more expensive, but it’s much less likely to cause problems down the road. Second, be sure to apply pressure when you’re taping. This will help ensure that the tape adheres properly and doesn’t come loose later on. Finally, don’t overdo it with the mud. You want just enough to cover the tape and smooth out any imperfections.

Now that you know the basics, let’s get started! The first step is to cut your strips of tape. You’ll want them to be about 18 inches long. Once you have your strips cut, it’s time to apply them to the wall. Start by putting a strip of mud on the wall about an inch from the corner. Then, take your first strip of tape and press it into the mud, making sure that the sticky side is facing down. Next, take your second strip of tape and do the same thing, overlapping the first strip by about half an inch. Continue until you’ve reached the end of the wall or run out of tape.

Once all of your strips are in place, it’s time to start mudding them over.


Now that you know how to tape drywall corners, you can get started on your next home improvement project. This is a relatively easy task that anyone can do, so don’t be discouraged if it seems daunting at first. With a little practice, you’ll be able to tape drywall corners like a pro in no time.
