Drywall might seem like a simple process at first glance. However, not using the proper drywall framing techniques, materials, and tools can lead to common drywall mistakes. In this blog, we will share 12 top drywall tips to perfect your drywall construction projects.
1. Pay attention to drywall mud consistency
Premixed drywall mud, also known as drywall compound, joint compound, and joint cement, is a “ready-to-use” product that can save some time and mess. However, premixes are not always the perfect consistency. Thick compound creates bubbles that interfere with proper adherence of drywall tape.
The ideal consistency should be similar to pancake batter: thin enough to smooth over the tape, but thick enough that it doesn’t drip. A good rule of thumb when using premixes is to add a small amount of water a little at a time to get the desired consistency. Avoid adding too much water, as a runny compound causes the tape to rip.
2. Apply the right amount of mud
Applying the right amount of mud ensures it is easy to apply, dries faster, and is smoother when it comes time to sand. Adding too much mud leads to the following issues:
- You’re going to work a lot harder trying to remove the excess mud with your drywall tools.
- It will be harder to sand the surface once the mud dries, increasing the risk of ruts and bumps.
- A thick coat of mud takes longer to dry, so you’ll spend more time completing your drywall project.
- Excess mud dampens the drywall tape, making it more fragile and increasing the risk of tears.
To assess whether you’ve added the right amount of mud, you should be able to see the tape through the first coat.
3. Apply more than one coat of mud
It usually takes about three coats of mud to secure the tape and seal the joints. As mentioned, the first coat should be thin enough to still see the tape. As you apply additional coats, use consistent vertical strokes, ensuring the mud covers the taped corners and edges.
Before applying a second coat, the compound should be completely dry. Look for slightly darker spots in the mud, as this indicates you need more drying time. Proper drywall drying times can take up to 24 hours and is a critical step for smooth sanding.
4. Sand between mud coats
Sanding between mud coats is essential to avoid creating an uneven surface. Ridges and bumps are a common drywall mistake that makes it harder to use your knife to spread the next coat. Drywall sanding keeps the surface smoother, while also improving adherence for additional coats.
5. Understand the different types of drywall compounds
The two most common types of drywall compounds used by drywall contractors are taping compounds and finishing compounds. As the name implies, taping compound is used for the first coat. It hardens faster and helps fill the cracks between drywall joints.
The final two coats use finishing compound to achieve a smoother application that is easier to sand while ensuring a smooth drywall finish. However, you can also look for an all-purpose compound that can be used for all coats.
6. Sand for perfection
Drywall is finicky work that tends to show every little imperfection. Although you might think paint will hide imperfections, it tends to make them more visible. Therefore, it’s important to work diligently.
Be sure to feel for ridges and bumps, and stand back to critique your work. If you find that your surface is bumpy, never apply more compound, as this just makes things worse. Instead, continue to sand until you achieve a smooth surface that is ready for your paint primer.
7. Use the right drywall tools
The drywall tools you choose impact how easily you complete each task and the results you achieve. The most important drywall tools are your knives, which come in different blade sizes. Drywall contractors usually recommend using the following guidelines when selecting the right drywall tools:
- Choose a 2” to 4” straight-edged knife for the first coat so you can work the compound into the seams.
- Switch to a 10” to 12” knife for the final coats, as well as when working on larger areas.
- Always use a corner knife to tackle both inside and outside corners.
- Use a 6” straight-edged knife for drywall patch jobs.
8. Tap the tape into place
Once you apply the first coat of mud to the joint, use your fingers to tap the drywall tape into place every foot or so. You can then swipe your knife over the tape to embed it into the mud.
You want to use a gentle touch, as too much pressure will move and/or tear the tape. Smooth, gentle, horizontal swipes will get the best results, filling the joints and adhering the tape.
9. Leave gaps between drywall boards
Cutting drywall to an exact measure doesn’t provide any wiggle room. As a result, you have to force the boards into place, leading to bulges or cracks. By including a ⅛” gap in your measurements, the joints are easily covered with tape and mud, and you avoid having to remove and recut damaged boards.
10. Keep boards as large as possible
Avoiding unnecessary cuts will help create a smoother drywall finish, while also making your job easier. The fewer the joints, the less tape and compound you need, and the faster the installation.
11. Avoid drywall joints above doors or windows
A common drywall mistake that leads to joint cracks is improper installation above doors and windows. This is usually caused by aligning the drywall edges with the edges of the opening.
To avoid drywall repairs in these areas, it’s best to notch out a larger piece of drywall that sits over either side of the opening. This drywall technique avoids compound cracks as the house shifts and settles.
12. Always space and sink your drywall fasteners
Drywall screws or fasteners should be slightly sunk to avoid popping. Spacing screws every 12” to 16” creates a more secure fit to avoid issues such as buckling walls and sagging ceilings.
