Editing Drywall Finishing Process

Drywall finishing techniques (also called taping and mudding) involve applying joint compound ("mud") and tape to hide seams, screws, and corners after hanging, creating a smooth surface for painting. Professionals use hand tools for small jobs or automatic tools for speed on large projects. The process typically requires 3 coats, drying time (often overnight), and sanding between coats.
Step-by-Step Basic Hand Finishing Process

Preparation
Install corner bead on outside corners (metal, vinyl, or paper-faced for easier finishing). Mix joint compound to a creamy consistency (pre-mixed "all-purpose" is common for beginners; "hot mud" sets faster for pros).Paper-faced vs. metal corner bead:

First Coat (Taping Coat)
Fill screw heads with compound. Apply a bed of mud over seams, embed paper or mesh tape into it, then wipe excess with a taping knife (4-6 inch). Feather edges to blend.Embedding paper tape in mud:

Second Coat (Fill Coat)
After drying, apply wider layer (8-10 inch knife) over taped seams and corners, feathering outward for smooth transition. Cover screw heads again.Applying compound with wider knives:

Third Coat (Finish Coat)
Use 10-12 inch knife for even wider, thinner layer. Focus on feathering to eliminate ridges.
Sanding
Sand lightly between coats and finally with 150-220 grit on pole sander or hand sander. Use dust control (vacuum sander) to minimize mess.Pole sanding in action:

Advanced/Pro Techniques

Automatic Tools: Pros use "bazookas" (automatic tapers) to apply tape and mud simultaneously, plus flat boxes and angle heads for faster, consistent coats.Automatic taper (bazooka):

Level 5 Finish: Highest quality—apply thin skim coat over entire surface after standard finishing for ultra-smooth result, ideal under critical lighting or gloss paint.Skim coating for Level 5:

Final Result
A perfectly smooth wall, invisible seams:

Tips: Work in good lighting to spot imperfections; patience is key—rushing leads to visible flaws under paint. This dusty, repetitive job rewards practice and proper feathering.
