Sheet Size Considerations
Longer sheets (4′ x 12′) require fewer seams and cost less to finish, but are more difficult to install and may not fit in tight spaces. A 4′ x 8′ sheet weighs about 54 lbs, while a 4′ x 12′ sheet weighs about 82 lbs.
Thickness Selection
1/2″ drywall is standard for interior walls. Use 5/8″ fire-rated drywall for garages, kitchens, and ceilings. Use 1/4″ for curved surfaces or over existing walls.
Drywall Types
Mold-resistant drywall is best for bathrooms and basements. Fire-resistant drywall is required in garages and furnace rooms. Soundproof drywall is ideal for home theaters and bedrooms.
Installation Tips
Install ceiling drywall first, then walls. Start from the top of walls and work down. Stagger seams to increase wall strength. Leave a 1/4″ gap at the floor to prevent moisture damage.
Finishing Tips
Apply three coats of joint compound for a smooth finish. Allow each coat to dry completely before sanding. Use corner beads for clean, durable corners. Prime before painting to ensure uniform absorption.
Safety Considerations
Always wear a dust mask when sanding drywall. Use safety glasses to protect your eyes. Get help when lifting heavy sheets to prevent back injuries. Use a panel carrier tool to make transportation easier.
