How to Finish Drywall: Tips for Finishing Drywall - 2024 | Best Drywall Finishing Services

Finishing drywall is a crucial step in the drywall installation process. It involves applying joint compound (also called "mud") over the seams, screw holes, and corners to create a smooth surface that’s ready for paint. Proper drywall finishing can make the difference between a professional-looking wall and a wall that shows seams and imperfections.

Here’s a step-by-step guide to finishing drywall how to repair drywall, along with tips and techniques to help you achieve a perfect finish.

 

 

 

 

Materials and Tools Needed:

  • Joint compound (pre-mixed or powdered)
  • Drywall tape (mesh or paper)
  • Putty knives (4", 6", and 12")
  • Sanding block or sandpaper (fine grit, 120-150)
  • Sanding pole (optional for high areas)
  • Dust mask
  • Taping knife or corner trowel (for corners)
  • Mud pan (to hold compound)
  • Primer (for finishing before painting)
  • Drop cloth or plastic sheeting (for dust protection)

Step-by-Step Process for Finishing Drywall: Best Drywall Finishing

1. Taping the Seams

Prepare the Surface:

  • Check for Protruding Screws or Nails: Use a screwdriver to ensure that all drywall screws are slightly recessed beneath the drywall surface but not breaking the paper.
  • Clean the Area: Brush off any dust or debris from the seams and screw holes to ensure proper adhesion.

Apply Drywall Tape:

  • Paper Tape vs. Mesh Tape: Paper tape is stronger and works well for seams, especially in corners, while self-adhesive mesh tape is easier to apply but can be prone to cracking over time.
    • Tip: Use paper tape for flat seams and inside corners, and mesh tape for smaller repairs and minor cracks.
  • Embed the Tape: For paper tape, spread a thin layer of joint compound (about 1/8") along the seam using a 4” or 6” putty knife. Immediately press the tape into the wet compound, smoothing out any bubbles or wrinkles with the knife.
  • Cover Mesh Tape: If using mesh tape, apply it directly to the seam, then immediately cover it with joint compound.

2. Applying the First Coat of Joint Compound

  • Load the Knife: Scoop a small amount of joint compound onto your 6” putty knife. You’ll want enough to fill the seam but not too much to create a mess.

  • First Coat on Seams: Starting at the top, apply joint compound over the taped seams in a smooth, even layer. The compound should extend about 2 inches on each side of the seam. Use smooth, continuous strokes, holding the knife at about a 30-degree angle.

  • Cover Screw Holes: Use the knife to apply a small dab of joint compound over each screw hole. Smooth it out with the knife.

  • Inside Corners: For inside corners, use a taping knife or corner trowel to apply compound in both directions. After embedding the paper tape in the corner, apply a smooth coat over the tape on each side of the corner.

  • Outside Corners: For outside corners, cover the metal corner bead with a layer of compound using a wider knife (like a 6” or 8” blade). Feather the edges outward to blend it with the surrounding drywall.

Let It Dry: Allow the first coat to dry completely. Depending on the joint compound you use, this could take anywhere from 12 to 24 hours. (Quick-setting compound, or "hot mud," can dry faster.)

3. Applying the Second Coat

  • Switch to a Wider Knife: For the second coat, switch to a wider knife (10" or 12"). This helps feather the edges further and smooth out the surface.

  • Feather the Edges: Apply a second coat of compound over the seams, extending it about 4-6 inches beyond the first coat. The goal is to create a gradual slope from the seam to the surrounding wall. Use wide, sweeping motions to avoid creating ridges.

  • Screw Holes: Apply a second coat over each screw hole, smoothing it out with the larger knife.

  • Corners: Add a second coat to both inside and outside corners, using a taping knife to smooth out the surface and blend it into the wall.

Let It Dry: Allow the second coat to dry completely before moving on to the final coat.

4. Applying the Third Coat

  • Final Smoothing: The third coat should be the thinnest and most refined coat. Use the 12” knife to apply a thin layer of joint compound, extending it several inches beyond the second coat. This final coat ensures a smooth, even surface across the entire seam.

  • Sanding Between Coats (if needed): Lightly sand any bumps, ridges, or imperfections before applying the final coat. Use fine-grit sandpaper (120-150 grit) to avoid scratching the surface.

Let It Dry: Once again, allow the final coat to dry completely.

5. Sanding the Final Coat

  • Check for Imperfections: Before sanding, hold a light at an angle to the wall to check for any uneven spots, ridges, or bumps in the compound.

  • Sanding: Use fine-grit sandpaper or a sanding sponge to sand the final coat of joint compound. Sand in a circular motion, applying light pressure. Focus on blending the edges of the compound into the surrounding wall to create a seamless surface.

  • Sanding Corners: Be careful when sanding inside corners, as it’s easy to sand through the compound or paper tape.

  • Dust Control: Sanding drywall creates a lot of dust, so wear a dust mask and use plastic sheeting or drop cloths to protect floors and furniture. A vacuum sander or sanding pole can help reduce dust.

6. Prime and Paint

Prime the Drywall:

  • Use a Drywall Primer: After sanding, it’s essential to apply a coat of drywall primer. This seals the joint compound and provides a uniform surface for painting. Without primer, the patched areas may absorb paint differently than the rest of the wall, creating a noticeable texture difference.

Paint the Drywall:

  • Choose Your Paint: After priming, you can paint the drywall with the color of your choice. Use high-quality paint for a professional finish, and apply two coats if needed.

Tips for Finishing Drywall Like a Pro:

  1. Use the Right Tools: Invest in high-quality putty knives, taping knives, and sanders to make the job easier and improve the quality of your finish.

  2. Feather the Edges: Always feather the edges of your joint compound layers. This helps blend the seams and prevents visible ridges once painted.

  3. Work in Thin Layers: Avoid applying thick coats of joint compound, as they can crack or take too long to dry. Thin, even coats are easier to work with and create a smoother finish.

  4. Control the Dust: Drywall sanding creates a lot of dust, so wear a dust mask and use a vacuum sander if possible. Cover the floors and nearby furniture with plastic sheeting or drop cloths to minimize cleanup.

  5. Check for Smoothness: Use a light or flashlight at an angle to check the smoothness of the joint compound. Any imperfections will cast shadows, making it easier to spot and correct them before painting.

  6. Be Patient: Don’t rush the process. Let each coat of joint compound dry thoroughly before applying the next. Skipping this step can lead to bubbles or cracks in the finished surface.

  7. Use Quick-Set Compound for Speed: If you’re short on time, consider using a quick-setting joint compound ("hot mud"). It dries faster, allowing you to apply multiple coats in one day.

Finishing drywall is an art that takes practice, but with patience and the right techniques, you can achieve a smooth, professional finish. By following the steps above and using thin, even coats of joint compound, you’ll ensure that your walls look flawless and ready for paint. Whether you’re a DIY enthusiast or a first-time renovator, mastering drywall finishing is a key skill in any home improvement project.
