Commonly Asked Questions:

How to joint drywall?

If you’ve ever looked at finished drywall you’ve probably been left wondering how the gaps between the drywall sheets, or joints, have mysteriously vanished. The secret lies in the process of taping and then applying coats of drywall compound over the sheets.

To joint drywall, begin by adding a layer of drywall tape over each seam. Be sure to press the tape firmly into the seams.  Once that sets, it’s time to apply your first coating of compound. Add a thin layer of compound over the joint, and add more tape to it. Then, add another layer of joint compound with a taping knife. Sand down once dry. 

The next step is to add a filler coat to help fill out the joints. This will require using a smaller knife, about 6 inches, in order to feather and blend. Additionally, this process includes covering up any drywall nails or screws. Remember to remove any excess joint compound by scraping along the seams once this coat has dried.

With a wider knife, about 10 inches, smooth another coat of putty over the seams. To finish the drywall, add another third layer of mud once the second has dried. Ideally, a wider knife will give the best effect. You can also use a trowel to help you smooth the compound. 

What is the purpose of taping knives? And what are they used for?

Taping knives provide you with a smooth, flexible surface, allowing you pull joint compound along any grooves or seams so that the final product is as glossy and imperfection-free as possible.

Typically, these knives, also known as drywall knives, are used for drywall. However, contractors can also use them to scrap dry paint off hard surfaces or even remove caulk. Since these tools are thinner, they’re also great at slipping behind objects like mirrors or cabinet surfaces so that you can work them free with ease.

How to determine the right size taping knife

The size of the knife you need will depend on what step in the drywall process your working on. Smaller knives, such as 4 inch or 6 inches are perfect for the initial jointing step, enabling users to smooth the tape between the seams and also fill any gaps. Bigger knives work best for blending or smoothing surfaces, which is why they’re ideal to use in the later stages.

How to keep taping knives from rusting

If you’re a professional contractor, one of the biggest frustrations can be dealing with drywall tools that get rusty. Unfortunately, because these products are constantly exposed to both the joint compound and water they can rust pretty quickly.

While cleaning and drying off these tools after each use is a great preventative measure, sometimes it’s simply not enough. The best solution is to spray WD-40 on the tool after drying it off. This provides a protective layer from the drywall compound and prevents the development of rust.

What material should the taping knife be made of?

Taping knives can be made from a variety of materials—everything from plastic to carbon steel. Ideally, you want a taping knife that’s made of stainless steel, since this metal will never rust or corrode. However, some kinds of metal, depending on the coating used by the manufacturer, can also resist rust for long periods of times.

What are the advantages of using a taping knife during a job?

Taping knives allow you to easily create a smooth surface, which—although you may be able to accomplish with a trowel in the final phases—is really important in the first few steps. The smoother the initial mud layer you lay down, the more flawless the final product will be. These tools also allow you do more detailed work when applying the filler coat. The better you fill any gaps and cover any holes, the less apparent they’ll be when you apply the final layer.
