Things to Consider Before Buying Taping Knife

Taping knives, or you can say drywall finishing knives are very important to finish off your project. That’s why you have to get the perfect one.

Well, there are things that you need to consider when you think of purchasing a taping knife. We’re going to discuss them underneath so that you can easily pick out a preferrable one for completing your project.


This is the most important consideration while selecting a taping knife as the size matters. Yes, it does, even when you're plastering your drywall.

Smaller Knives

6-inch or smaller taping knives are mostly known as joint knives. You can use them at the first stage of your project as their smaller size will allow you to work in crevices and smaller spaces.

Not only that, but they'll also allow you to apply more pressure when forcing mud into holes and seams. They’re designed to work snugly into the corners.

Larger Knives

Knives with 6-inch or greater length and with a square shape are called taping knives. These work best at the time of finishing.

Because of their large size, you’ll be able to cover more space with lighter pressure. You can smooth down the tracks that are left by joint knives by using these large knives to get a clean surface.

Middle-Sized Knives

The 6-inch or 5-inch knives are the special ones, as they are suited for doing both mud application and finishing work. And these types of knives are mostly used by professionals for doing their projects.

Blade Material

Generally, three materials are used for making the blades of taping knives — carbon steel, stainless steel, and blue steel.

Carbon Steel

It is considered more flexible than others, which makes it suitable for smoothing and feathering. But the drawback with carbon steel is that it is prone to rust. So, maintaining it is going to be pretty tough.

Stainless Steel

The best part of stainless steel taping knives is that they can resist rust very effectively. Not only that, but this type of material is also very durable and long-lasting.

If you can maintain it properly, it'll last for years. But, its strongness makes it less flexible than other knives. As a result, you'll find it harder to feather mud or work in corners by using a knife blade made of stainless steel.

Blue Steel

Carbon steel that has been treated for resisting rust is called blue steel. This type of steel can resist rust more than carbon steel and is more flexible than stainless steel.

Experience drywall professionals use this type of steel to make accurate adjustments. However, it needs little maintenance than stainless steel. You can apply a thin coat of oil between uses to keep it in good shape.

Handle Material

This is another important consideration as comfort level depends on the type of material used for making the handle of a taping knife. There are three main materials that are used for making the handle.


These types of handles are popular for delivering comfort and durability. They also boast a beautiful look and are quite comfortable to hold. However, they are heavy and expensive.


Now, these types of handles are inexpensive yet durable. But taping knives with hard plastic handles are not so comfortable to hold while working.


This material offers both durability and comfort. The rubber handle offers an improved grip so that you can apply the mud with minimal pressure. You can use a knife with a rubber handle for feathering and finishing precisely with ease.

How to Use a Taping Knife?

The sole purpose of using a taping knife is to obtain a smooth finish of your wall. For that reason, you must know the absolute techniques of using it so that you can do the taping and mudding perfectly. Yet, it’s not all about techniques, you need to have patience as well as skill. These are the steps –

Taking Precautions

Since you’re going to work for a prolonged time with a mud knife, you have to wear gloves. Otherwise, your skin might get damaged.

Plus, keep a bottle of water while working, as you're going to work pretty hard, which will often make you dehydrate. Again, don’t forget to wear old clothes because you’re going to use taping knives for mudding and layering.

Selecting Knife

You’ll find taping knives in different sizes from 6-inches to 12-inches and even more. Now, the size is going to play a significant role in delivering you smooth mud coats. That's why if you need to apply multiple coats, you should get three different sizes of a knife.

Usually, the first coat requires large amounts of mud. That’s why choose a smaller knife as it’ll give you control over the quantity of mud you’re going to apply. And for applying other coats, use a taping knife larger than the prior one.

Holding a Knife

Hold your knife by placing your thumb below the handle and two fingers on the top of the blade. This way, you'll be able to apply pressure at places where you need it. It's important for you to remember that you can hold an offset handle with a full grip, yet you can place the blade flat against your drywall surface.

Spreading the Mud

Start spreading the mud following a horizontal direction on plane surfaces. But when it comes to corners, you have to tilt the blade to a 45-degree angle before application.
That way, you'll be able to create a smooth joint within perpendicular drywalls. This time apply the mud in a vertical direction to do the work more easily and faster.


Finally, a taping knife can very likely poke through the wet coat, which will ruin all the hard work that you’ve done so far. So, check whether the first coat has dried or not before applying a new coat.

Frequently Asked Questions

1. What size of a taping knife do I really need?

You can use both 6-inch and 4-inch knife for taping as well as slopping mud into places. And for feathering and applying final coats, you’re going to need a 12-inch knife. So, you’ll need each of them at least once for completing your project.

2. What is the difference between a taping knife and a putty knife?

A taping knife is used to spread and scoop drywall mud on joints and seams between panels. On the other hand, a putty knife is made to work for spreading putty smoothly into indentations in walls.

3. How many drywall muds coats do I need to apply?

Apply one layer of drywall mud on a bare wall for holding the tape. You can immediately apply another coat after laying the tape and scraping it. When the coat dries, you can use a wider knife to give a topcoat by applying the third layer.

4. What is the difference between joint compound and drywall mud?

A joint compound is also called drywall mud, which is a gypsum-based paste. It is used during drywall installation to finish corners and joints. It's also very useful for repairing holes and cracks in existing plaster and drywall surfaces.

5. Why my drywall mud is cracking?

Either the drywall mud on your wall has dried out too quickly, or the application was overly thick. Don't need to start over again; rather, you can repair the cracked area after the mud dries out completely.

Though there’re overwhelming options out there, we’ve discussed all the factors that’ll help you to get the best taping knife effortlessly. So, get the one that suits your project.
