drywalling

Drywalling is the process of installing gypsum board sheets on interior walls and ceilings to create smooth, paintable surfaces. Drywall panels are typically fastened to wooden or metal framing and finished with tape and joint compound to conceal seams and fasteners.

Materials commonly used include gypsum boards of various thicknesses (most often 1/2 inch for walls and 5/8 inch for ceilings or fire-rated applications), with facing paper. Specialty boards are available for specific conditions, such as moisture-resistant or mold-resistant types, and cement boards are used in wet areas. Fasteners are drywall screws or nails, and corner beads help finish external corners. Joint tape and joint compound seal seams and fastenings.

Installation steps involve measuring and cutting panels to fit, attaching them to studs or joists with appropriate fasteners, and checking for plumb and level. Seams are covered with tape, then multiple coats of joint compound are applied, dried, and sanded for a smooth finish. After final sanding, the surface is primed and painted. Finishing textures such as orange peel, knockdown, or skip-trowel may be applied for appearance.

Cement boards and other substrates are used in bathrooms or kitchens where higher moisture resistance is required, but they are not traditional drywall. Drywalling can influence acoustics and fire resistance and remains a common method in modern interiors due to its speed and uniform finish.

Repair involves patching holes with a patch kit, re-taping and refinishing joints, or replacing damaged panels. Safety considerations include dust control and protection, proper handling and disposal of waste, and ensuring electrical or plumbing work is completed before drywall installation.
