Understanding Drywall Types
Different types of drywall are designed for specific applications and environments.
- Standard Drywall Regular 1/2" thickness for most interior walls. Most economical option.
- Moisture-Resistant (Green Board) For bathrooms and areas with high humidity. Contains special coating.
- Fire-Resistant (Type X) 5/8" thick with special core for improved fire resistance. Required by code in certain areas.
- Soundproof Drywall Engineered to reduce sound transmission. Ideal for bedrooms and media rooms.
Installation Best Practices
Sheet Orientation
Install sheets horizontally for walls under 9 feet. This reduces joints and provides stronger walls.
Staggering Joints
Stagger end joints by at least 4 feet. Never align joints with door or window frames.
Screw Spacing
Space screws 12" apart on ceilings, 16" on walls. Keep screws 3/8" from edges.
Temperature Control
Maintain room temperature between 55-70°F during installation and finishing.
Finishing Techniques
- Taping Joints Apply tape centered over joints. Embed completely in joint compound.
- Multiple Coats Apply three coats of joint compound, feathering each coat wider than the last.
- Sanding Sand between coats and after final coat. Use appropriate grit sandpaper.
- Corner Beads Install on all external corners for protection and clean lines.
Common Issues & Solutions
Popped Nails/Screws
Caused by wood movement or improper installation. Replace with slightly longer screws in new location.
Cracks
Use paper tape instead of mesh for better crack resistance. Allow proper drying between coats.
Bubbling Tape
Ensure proper compound coverage and remove air pockets when embedding tape.
Moisture Issues
Use moisture-resistant drywall in humid areas. Ensure proper ventilation during and after installation.
