Pro Tips

✓ Standard 4x8 sheets cover 32 sq ft each — add 10% for waste and cutouts
✓ 1/2" drywall works for most interior walls; use 5/8" for ceilings and fire-rated assemblies
✓ Three coats of joint compound (tape, fill, finish) gives the smoothest result
✓ Pre-mixed joint compound is easier for small jobs; powder is cheaper for large rooms
✓ Screw drywall every 16" into studs — over-driving screws tears the paper face
