There are many different processes and methods that go into finishing drywall, and one of the most common is taping and floating. It can be difficult for beginners to do well but it is fairly straightforward and easy to get the hang of after a few attempts. Here’s a breakdown of what taping and floating is and how to go about doing it correctly to finish your next drywall project.

What is taping and floating?

Taping and floating refers to the way drywall is finished after it’s hung, and is performed in order to solidify the joint between two pieces of drywall so the plaster and paint that eventually go over it won’t crack later on.

Once drywall is hung, tape is applied to the joints where the drywall is joined with mud or joint compound, hiding the joints so the wall looks seamless.

Floating then takes place after the taping, wherein another layer of mud is applied on top of the tape to further smooth out the joint.

Here’s a more in-depth step-by-step breakdown of how to tape and float drywall.

How to tape and float drywall

Step 1

Apply a thin layer – between 1/8” and 1/4" thick – of mud to the joint using a drywall knife.

Step 2

Immediately apply a piece of mesh tape down the length of the joint. The tape should be centered over the joint.

Mesh tape is easier to use for a number of reasons. Paper tape is a little bit stronger but isn’t as easy to work with. Paper tape also requires at least 24 hours to dry once applied, whereas mesh tape can be worked on right away.

The tape is what ultimately will keep the compound that will eventually be applied over it from cracking once it dries.

Step 3

Drag a drywall knife down the joint on top of the tape, applying enough pressure to embed the tape and to squeeze out most of the mud from underneath the tape. Be careful not to squeeze out all of the mud, as you’ll still need some to secure the tape to the drywall.

Step 4

Wait for the mud to dry and apply another coat of joint compound over the tape.

Step 5

Smooth out the compound using a drywall knife, feathering the edges of the drywall outward toward the surrounding drywall.

Step 6

Once the compound is dry (usually takes no more than 90 minutes), lightly sand down the areas that were taped and floated. Sand lightly enough that you’re not able to see any of the tape once you’re done.

Step 7

Repeat the steps of applying a thin layer of mud and smoothing as needed until you have a smooth, uniform appearance on all joints. The drywall is now ready to be primed for paint or wallpaper.
