A drywall project involves applying drywall as construction material such that it helps in making walls and ceilings. This material is also known as wallboard, sheetrock, plasterboard, or gypsum board. Drywalls are indeed useful for implementing several design aspects such as arches and eaves.

It is fast and straightforward to install these extraordinarily durable and low-on-maintenance drywalls. Yes, hanging drywall is hassle-free, provided you use the right tools for hanging it efficiently, though.  One of these tools is the drywall taping knife.

Also commonly known as a taping knife, a drywall knife is one of the essential drywall tools useful for spreading mud. This mud is also called the joint compound and is applied to the internal corners where walls tend to intersect. For this, usually, a right-angled knife is used.

The knife features a wide blade that performs the spreading job over the nail and screw indents in applying new drywalls. It is also useful for covering seams using a fiberglass or paper drywall tape.

A few more common uses of this knife include creating artistic wall finishes, smoothing coverings on walls, and patching holes. Read on to know more about drywall knives.

Overview of Drywall Taping Knives

taping drywall knife

Drywall usually consists of a gypsum core and a smooth paper on both the coarse and finish sides on the rear. Available in varying thicknesses, a drywall forms holes or gaps at the time of installation in between the adjacent boards.

The drywall taping knife, mud, and tape fill these holes and prevents them from breaking and coming apart. Using a drywall knife, mud is filled into the joint, and a layer of tape is then applied over it.

Again, an extra layer of mud is applied over the tape’s surface. Doing so makes sure that the joint is sealed and paves the way for light sanding and finishing once the mud dries completely.

A drywall knife usually has a handle made using plastic, metal, rubber, or wood. At the handle’s end, a thin metallic sheet or the blade extends outward to have a wider look than the typical taller appearance.

How to choose the Best Drywall Taping Knife

Size

Size is one of the essential features to consider when it comes to buying a drywall knife because it determines the construction phase for which the tool is suitable for.

The size range for these knives is 3 to 14 inches. The smaller ones, meaning 6” and smaller, are ideal for the initial drywall project phases. Due to the small size, these models are capable of penetrating smaller corners and crevices.

They also tend to use more pressure to make the mud go inside the seams and the holes that the screwing procedure has left behind. However, these smaller drywall knives are likely to make marks and result in uneven surfaces.

It is okay to have them during the initial stages, as adding another coat will make them intangible. On the other hand, larger models that are 6” and above are ideal for finishing, because they enable you to cover a greater area with lighter pressure.

The larger knives are also apt for leveling the tracks that the smaller knives may leave and feathering mud. Finally, they result in a clean surface towards the end phases of the project once detailing is over.

The most popular sizes are 6, 8, and 10-inch knives for usual drywall work, while the commonly used sizes range from 5 to 12 inches (5 to 30 cm wide). The smaller versions are known as spackle knives that are useful for patching small holes. The handle is well-balanced to facilitate clearance for fingers.

The 5- or 6-inch knife is worthy of your special attention, as it is middle-sized and is a part of a special niche. It is suitable for applying mud as well as performing detail/finishing work. As of now, it is the most-used size. Thus, many professionals prefer to have an array of 6-inch knives for any drywall project.

A 6-inch taping knife is of great significance, especially for drywall finishers. It is reserved for scooping drywall mud, coating angles, installing mesh tape, mixing hot mud, and cleaning many things such as buckets and boxes.

Although a 6-inch knife is more common than a 5-inch one, you will admire the benefits of the latter if you can get your hands on it. The 5-inch one is a general-purpose knife.

The sides of 5- and 6-inch knives are likely to curve smoothly from the edge to the handle. Unlike the larger knives of 8, 10, and 12 inches, a 6-inch knife typically does not feature square corners projecting from the handle before reverting to the edge.

In simple words, it has the shape of a half-circle instead of a rectangle. To be more precise, it is the shape of half ellipse and not an isosceles trapezoid. This shape was introduced originally to coat the internal drywall corners or angles. Further, the curved edge prevents gouging into the angle’s opposing side while coating the angle’s one side.

For getting the best 6-inch knife, you should look for flexibility, as it is the most important factor. For an experienced tape, a certain level of flexibility is desirable for using the knife. A more flexible knife is preferable while coating angles and adding a layer of tape, while a stiff knife is ideal for scraping the material.

The former, however, needs more pressure to press the mud from the pear tape’s rear. Only an experienced finisher will be able to feel it. A few finishers go for a stainless steel model, but it is usually stiffer. For some, it is too stiff.

Most of the 4-, 6-, and 8-inch drywall knives are preferred for applying the mud, taping, and removing surplus mud. A 6-inch knife is for scooping and smoothing wet mud into the seams. A larger version is for feathering the same over a wider area to make seams less tangible post wall finishing and painting.

Thus, a 12-inch model is kept reserved for feathering areas wherein a ceiling or a wall could be bumpy or inclined. This is because its larger surface facilitates a slow surface transition due to which sloping becomes less visible.

You will also come across corner taping knives, which are commonly called drywall corner trowels. They feature a characteristic 90-degree angle in the center for use on the drywall’s internal corners where the tape is to be applied.

90-degree angle presses tape and mud into both sides of the corner together to render a more consistent and even edge. Trowels have a blade with a larger surface area than normal to ensure quick.

It is usually beneath an offset handle due to which there is no way to leave indentations or finger marks. However, trowels can ake your practice more than usual, especially for feathering, so that you learn to use them well.

Further, they are not meant for application in small areas. Hence, professionals prefer a mix of drywall knives and trowels to execute projects. Unlike knives, the trowels of professional-grade are made only of stainless steel, because trowels need not be as flexible as the knives.

Drywall Knife Blades

The blade of a drywall knife is usually made up of stainless steel, blue steel, or carbon steel. The carbon steel models are fairly uncommon, and you will see them in use occasionally. Let’s understand the pros and cons of these materials to know the differences and choose the right blade material.

  • Carbon Steel: It is more flexible than stainless steel. Hence, it is suitable for fine tasks such as smoothing and feathering. Nevertheless, it is susceptible to rusting due to which it is challenging to maintain it. Thus, it is not so famous as a drywall knife blade material.
  • Blue Steel: Is typically carbon steel but is processed to ensure rust resistance. This is evident with a dark, blue-black surface due to which this material gets its name. The resulting material is more flexible than stainless steel as well as more resistant to rust than carbon steel. Generally, this material is what more experienced drywall experts prefer, as they make the best use of its flexibility. These experts have infallible skills and the experience to use the flexibility for making very fine tunings. However, blue steel needs a bit of more maintenance than stainless, but applying a light oil coat in between uses keeps the material in good shape.
  • Stainless Steel: Is an exclusive form of steel that is resistant to rust and contains not more than 10.5% chromium. It is used for making taping knife blades due to its durability; it is hard and long-lasting if the user maintains it properly. A stainless-steel blade, due to this reason, can last for several years. On the flip side, the same hardness of the material makes it less flexible than other knives. Thus, a drywall knife having a blade made up of stainless steel will make you face a tough time while feathering mud and reaching the corners. It is also susceptible to permanent leaning than other types of blades. Moreover, stainless steel is tougher to restore to a new edge than softer steel assortments.

Handles

A drywall knife’s handle is commonly made using rubber, plastic, or wood. Each of these materials has its pros and cons. Which one is suitable for you depends on factors such as comfort, durability, and price.

Wooden handles are conventional as well as famous amongst those whose top priorities are longevity and comfort. They look pretty, hold up to the diverse task demands, and are comfortable to handle.

However, they are costlier as well as bulkier than other handle materials. Thus, although beautiful, they can be heavy enough to make carrying difficult for you.

On the other hand, plastic is more affordable and durable due to which it is an ideal choice for those on a strict budget. With minimal cost, a plastic handle lasts for a long time. On the flip side, hard plastics are usually considered less comfortable than a few other options.

For those who want the right balance of comfort and durability, rubber is a great option. You enjoy a better grip with a lighter hand while working with the drywall mud. Thus, knives having a rubber handle are perfect for feathering and finishing tasks demanding maximum precision.

Apart from the material, a drywall knife handle is available in more than one design. The design tends to influence the comfort or use of the knife. You choose from offset, long, or coated handles.

The offset design does not have the handle in line but outlines with the blade. This paves the way to more clearance for fingers and brings down the likelihood of inadvertently marking the mud using knuckles. It also enables you to take the flatter to the wall so that getting an ideal finish is easy.

On the other hand, a few drywall knives come with an extended handle. It becomes easier to reach areas close to the ceiling or those that are hard to access. However, you also have to carry more weight than other handles, which negatively affects the ease of carrying.

A few drywall knives have plastic handles that come coated with another material, which is usually a soft-to-touch material such as rubber. Such handles provide the comfort, grip, and light touch without making you spend lavishly and while ensuring you the durability advantage.

Drywall Joint Knives vs. Taping Knives

8-Inch Soft-Grip Stainless Steel Drywall Joint Knife

A few makers tend to differentiate between taping or drywall knives and joint knives. Typically, joint knives are smaller being six inches and below; whereas, taping knives are bigger.

Further, joint knives are usually analogous to putty knives in terms of shape, which is rounded, sloping sides to the handle. However, sharpening mechanisms are not the same.

On the other hand, drywall or taping knives are usually more rectangular. Although exchangeable in a few applications, the shape variance stems from the requirement for a knife that can go inside corners.

A smaller size combined with a rounded shape easily fulfills this requirement without scraping or damaging the surface. However, these days, many professionals are getting inclined towards a trowel specially designed for this task.

Given below is one of the best drywall joint knives available in the market.

Drywall Taping Knives vs. Putty Knives

WORKPRO Putty Knife Set Stainless Steel Made 4-piece 1.5",3

Many consider these two knives to be the same and interchangeable. However, this is not true. Both putty and drywall knives have a flat blade and a handle.

Despite this, although you can intermittently use them for akin tasks, it is impossible to replace one with the other. As per their sizes, drywall knives have distinct purposes. Still, both types tend to save time and labor.

A putty knife is made to spread putty into dents without fingers. It is typically smaller than a taping knife. This knife is usually lightweight and has a blade whose width varies from 1.5 to 6.0 inches.

The blade can be rigid. It is likely to have a beveled edge for scraping or a bit flexible for spackling or spreading putty. Blades made using stainless steel, or other metals are usually an integral part of the toolbox and workshop.

However, for fast tasks, there are disposable plastic putty knives that are inexpensive. The handle is typically short that is around a palm’s width due to which the tool is easy to hold and control in tight areas.

On the other hand, the drywall taping knives are trade tools for contractors who keep more than six such knives for spreading and smoothing joint compound. Both knives are considered ideal for scraping.

The rigid, beveled blade of a putty knife slips easily underneath loose and peeling paint to scrape it away before repainting. The drywall blade scrapes bits of dried mud from taped walls and even removes old wallpaper.

The drywall knives are exclusively used on walls at the time of mudding. Their blades may feel like too wide at the time of re-taping and repairing small spots such as a narrow wall strip between the corner and a door frame. This is where putty knives are useful for smoothing compound and scraping away thin wallpaper strips.

Cleaning Drywall Knives

Cleaning any knife is essential if you wish to increase its lifespan and preserve its quality of life. Water and elbow grease are enough to clean a taping knife.

It is essential to clean your knife as soon as possible. This is because allowing the drywall mud to stay on the blade will harden it. It will be difficult for you to clean the knife after.

The accumulation of this hardening is also likely to impair the blade’s use until you remove all hardened mud. You may also see rust on the metallic surface of the knife.

Conclusion

A drywall taping knife is an essential part of a toolkit of any drywall DIY enthusiast or professional. It is designed for applying joint compound or drywall mud, applying tape, and finishing.

These knives are available in different sizes, blade and handle materials, and handle designs. Consider these factors for choosing the most suitable one for your project. There are many overwhelming options when it comes to buying drywall knives. Of all the sizes available, the 6-inch version is the most versatile size.

Still, it is not wise to stick to this standard size, as each project shall dictate its size requirements.
