What Size Knife Is Best For Taping Drywall?

The best size knife for taping drywall is usually around 4 or 6 inches. These smaller versions are joint knives.

They’re ideal for putting down tape and placing the first layer of drywall mud. 

After using your joint knife, you’ll switch to a taping knife for subsequent layers.

Is A Drywall Taping Knife Necessary?

Yes, a drywall taping knife is necessary. While you should apply the first layer of mud with a joint knife, you need to apply subsequent layers with a taping knife.

This is because smaller joint knives allow for more pressure and can help you quickly fill divots or a drywall joint. But, they leave behind indents and uneven mud applications.

So, after using your joint knife, you’ll add the remaining layers of mud with a taping knife. A taping knife will help you feather out mud for a more even, less rough finish.

What Drywall Knives Do Professionals Use?

One of the top drywall taping knives professionals use is the Dewalt 16 inch Big Back Taping Knife.

This knife’s long blade allows for even application and easy feathering of the joint compound. It’s also lightweight, has a soft-grip handle, and comes with a lifetime warranty.

What Is The Difference Between A Taping Knife and A Joint Knife?

Joint knives have smaller blades and rounded edges. They are ideal for applying the first coat of drywall mud and the tape.

Their curved edges can also aid in putting mud into the inside corners of a wall. 

A joint knife looks very similar to a putty knife.

Drywall taping knives have blades that are usually at least ten inches long. They are ideal for applying and smoothing mud.

In addition, their long blades help fix imperfections that the joint knife caused during the first layer.

Are Taping Knives Curved?

Taping knives are square on the sides. Joint knives generally have curved sides and look similar to a putty knife.

What’s The Difference Between A Drywall Taping Knife and A Scraper?

Scrapers have very stiff blades that can scrape things off the wall. For example, in a drywall job, you may use a scraper on any left behind mud when doing a repair.

However, since the blades are so stiff, they are not ideal for applying joint compound.

Drywall taping knives have a flexible blade that allows you to apply pressure without causing damage to the drywall.

Will Using The Wrong Size Knife Damage Your Walls?

Using the wrong size knife won’t necessarily damage your wall, but it can make achieving a smooth finish hard to accomplish. 

When finishing your drywall, start by applying your first coat and your tape with a 6-inch knife. This small knife will help pack mud into the seams and screw indentations.

Next, use a drywall taping knife with at least a 10-inch blade for your second coat. 

This longer-bladed knife will help you achieve the best finish.

What To Look For When Buying A Drywall Taping Knife?

Design Of The Handle

When choosing a drywall taping knife, the handle should fit your palm nicely. Since you’ll be using the knife to apply several layers of mud, it needs to feel good and not cause any wrist or hand pain.

Durability

Of course, a drywall taping knife needs to be durable. It should have a corrosion-resistant blade, a well-made handle and ideally, come with a warranty or guarantee.

Blade Size 

With a drywall taping knife, the blade size is essential. You’ll want a blade that’s at least ten inches long.

However, some professionals prefer even longer blades, up to 16 inches.
