Drywall is the most common building material used to create interior walls in modern homes. It's easy to repair if you have the proper compounds, tape, and tools. Drywall material accepts most interior paints and primers, and you can also use mud to create attractive textures. This wall surface holds up to regular use but is easy enough to cut with special installation tools. That makes it simpler to install wall switches, electrical outlets, vents, and other features.
