How to Finish Drywall: A Step-by-Step Guide to a Smooth, Professional Finish

(4) Specific steps

Ensuring each step is done accurately when completing drywall will help you achieve a flawless wall finish. Let’s walk through each step in detail to guide you in completing this task quickly and precisely.

Step 1: Gather Your Tools and Materials

Before starting, make sure you have the essential tools for the job:

• Drywall Tape: Whether you’re using paper drywall tape or fiberglass mesh tape, it’s crucial for preventing cracks at the seams.
• Joint Compound: Choose the correct type of joint compound for each step to ensure smooth coverage and strong adhesion.
• Putty Knife: Used for applying and spreading joint compound.
• Sanding Block: Necessary for sanding the surface to a smooth finish once the mud has dried.

Step 2: Taping Drywall Joints

Taping is critical for preventing cracks and ensuring the drywall seams are strong. Follow these steps to do it correctly:

1. Choose the Right Tape:
   • Paper Tape: Provides a strong bond and is best for most applications, helping prevent cracks.
   • Fiberglass Mesh Tape is ideal for areas needing additional strength, especially in cases with more significant cracks.
2. Embed the Tape:
   • Apply a thin layer of joint compound over the seams and press the tape into it, ensuring it is fully saturated with the compound.
   • Avoid bubbles and wrinkles to ensure a smooth and stable bond.

Step 3: Applying Joint Compound (Mud Process)

Applying a joint compound is essential for achieving a smooth, even surface. Here’s how to do it properly:

1. First Coat:
   • Use your putty knife to apply a thin, even layer of joint compound over the tape, covering it completely.
2. Drying Time:
   • Allow the first coat to dry completely, which usually takes around 24 hours, depending on the temperature and humidity.
3. Second and Third Coats:
   • After the first coat has dried, apply the second and third coats, extending the coverage to feather out the edges each time for a seamless finish.
4. Feathering the Edges:
   • Use a feathering technique to gradually taper the edges of the compound so that it blends smoothly into the surrounding drywall, eliminating noticeable ridges.

Step 4: Sanding Drywall to Make It Smooth

The final step is sanding to ensure a flawless, smooth surface. Follow these tips for the best results:

1. Choosing the Right Sanding Tool:
   • Sanding Sponge: Best for small areas or detailed spots that require manual work.
   • Pole Sander: Ideal for larger areas of the wall to increase efficiency.
2. Dust-Free Sanding Techniques:
   • Use a dust-free sanding tool to minimize mess and keep your workspace clean.
3. Hand Sanding Difficult Areas:
   • Carefully use a sanding sponge to smooth out any hard-to-reach areas for corners and edges.
4. Inspecting for Imperfections:
   • After sanding, thoroughly inspect the wall for any imperfections or uneven spots. If you find any, use a joint compound to fix them before proceeding.

Step 5: Apply Second and Third Coats to the Drywall

After you’ve sanded the first layer, it’s time to apply the second and third coats of joint compound. This step is crucial for achieving a seamless surface.

Feathering Technique: When applying the second and third coats, use the feathering technique. This involves gently tapering the edges of the compound to ensure a smooth, seamless transition between the joint compound and the surrounding drywall. Feathering helps eliminate noticeable ridges and creates a flawless finish.

Drying Time: Allow sufficient drying time between each coat. Drying time typically ranges from 24 to 48 hours, but it can vary depending on temperature and humidity. Be patient and let each layer dry completely before applying the next to prevent any issues with the finish.

Step 6: Finish Drywall Inside and Outside Corners

Inside and outside corners require extra care to ensure a clean and sharp finish. Follow these steps for perfect corners:

Taping Inside Corners: Start by applying tape to the inside corners and covering them with joint compound. This will prevent cracks from forming and help the compound adhere smoothly.

Corner Beading: To get that crisp, defined edge, install corner beads on the outside corners. Once in place, cover the bead with a joint compound to finish the look. Corner beads help create strong, clean corners that last.

Step 7: Prime and Paint for a Finished Look

Now that your drywall is smooth and dry prime it and paint it to achieve a flawless finish.

Priming Before Painting: Always prime your drywall before applying paint. Priming helps the paint adhere better and provides a more even finish. Skipping this step can lead to uneven color and less durable results.

Choosing the Right Primer: Be sure to choose a primer specifically designed for drywall. This ensures proper adhesion and prevents paint from soaking into the surface unevenly.

Avoiding Common Painting Mistakes: Don’t apply too many coats of paint to avoid common mistakes. More isn’t always better. Also, ensure the primer is completely dry before you start painting to prevent issues with adhesion.
