Professional Drywall Installation and Finishing Techniques

Planning Your Installation

Orient panels (horizontal/vertical) to minimize joints—especially end-to-end seams (harder to tape than tapered edges). 8' walls: vertical. Higher walls: horizontal with staggered seams, or 10–12' panels vertical.

Handling and Safety

• 5/8" 4x8 sheet = 58 lbs; often bundled in pairs—separate before moving
• Sanding/power cutting creates hazardous dust—wear respirator, avoid power tools on drywall

Corner Finishing

Outside Corners: L-shaped perforated metal corner bead. Tin snips to length. Nails (not screws) 9" o.c. through flanges. Compound at 45°—one flange at a time. Clean corner edge between flanges.

Inside Corners: Paper tape creased lengthwise. Thin compound both sides. Press tape in. Embed with broad knife—one wall at a time (dry between) or corner tool for both.

Smoothing and Priming

• Joint compound application takes practice—expect rough first attempts
• Light sanding with fine grit; avoid roughing face paper
• Wet sanding (damp sponge) eliminates dust, preserves paper—best for minor flaws
• Joint banding (compound telegraphing through paint): prime with porosity-equalizing sealer (e.g., USG First Coat)

Timeline

Two people: medium room + ceiling in a weekend. Taping/mudding: 3+ additional days (drying between coats).
