Walk into just about any home or business in the U.S., and you’re probably surrounded by it—drywall. It’s the smooth surface your walls are made of, the base for your paint or wallpaper, and the background of your daily life. But what exactly is drywall?
Whether you’re a homeowner, a DIY enthusiast, or just drywall-curious, here’s a straightforward breakdown of what drywall is, what it’s made of, and why it’s used in nearly every building today.
What Is Drywall?
Drywall—also known as sheetrock, gypsum board, or plasterboard—is a flat panel made from calcium sulfate dihydrate (gypsum), typically pressed between two thick sheets of paper. It’s used to create the interior walls and ceilings of residential and commercial buildings.
It’s lightweight, easy to cut and install, and ready for paint, texture, or wallpaper once it’s finished.
What Is Drywall Made Of?
At its core, drywall is made up of gypsum, a naturally occurring mineral that’s ground into a fine powder and mixed with water to form a slurry. This mixture is spread between heavy-duty paper liners and then dried into rigid boards.
There are also special types of drywall made for different environments:
- Green board – moisture-resistant, ideal for bathrooms
- Purple board – mold- and moisture-resistant
- Fire-rated drywall (Type X) – used in garages and between units in multifamily buildings
- Soundproof drywall – made with additional layers to reduce noise
Why Is Drywall Used?
Drywall became the standard wall material in the mid-1900s because it offered huge advantages over traditional plaster:
- Faster installation – One worker can install drywall quickly with just a few tools
- Cost-effective – Cheaper than plaster and easier to repair
- Fire resistance – Gypsum naturally contains water, making it more fire-resistant than wood
- Smooth finish – Offers a clean, modern look that takes paint or texture well
How Is Drywall Installed?
Drywall is typically cut to fit, screwed or nailed into wood or metal framing, then taped and covered with joint compound (also called “mud”) to hide seams and screws. After sanding and finishing, the wall is ready for painting or decorating.
It’s a multi-step process that takes skill to make smooth and seamless, especially in high-visibility areas.
Can Drywall Be Repaired?
Absolutely—and that’s one of the reasons it’s so widely used. From small dents to large holes, drywall can be patched and blended so well that the damage becomes invisible. Professionals (like myself) use specific tools and techniques to ensure that repairs match the surrounding wall perfectly.
Final Thoughts
Drywall is more than just a wall—it’s the backbone of modern interior construction. It’s versatile, affordable, and designed to work efficiently in nearly every type of space.
Whether you’re building, remodeling, or repairing, understanding what drywall is helps you make smarter decisions about your home or property.
