What is Drywall?

what is drywall

Drywall, also known as plasterboard or gypsum board, is a panel made from gypsum and paper layers. People use it in the construction of interior walls and ceilings. People prize the material for its quick and easy installation, cost-effectiveness, and fire resistance. However, working with drywall requires safety precautions, like wearing a mask, to avoid inhaling harmful dust.

The history of drywall dates back to 1916 when the U.S. Gypsum Company invented it. Earlier versions, called plasterboard, were made in England as early as 1888. The company improved the product by adding wrapped paper edges and named it Sheetrock. Although it was initially slow to gain popularity, drywall became the standard for residential wall construction in the post-World War II building boom. Today, hanging drywall is the most common way to finish wall surfaces.

What Is Drywall Made Of?

Drywall is a building material made from a mix of gypsum plaster, cellulose, and fiberglass. To create drywall panels, a layer of wet gypsum plaster is placed between two strong paper or fiberglass sheets. The mixture is then dried in a special chamber, making it strong and sturdy. Once dry, it’s ready to use for building walls and ceilings.

Is Drywall Safe?

Drywall is generally safe when it’s intact and stable. However, when it’s cut or damaged, it releases harmful dust particles that can be harmful if inhaled. The dust contains known carcinogens like formaldehyde, acetaldehyde, and crystalline silica, which can cause health issues. Installers need to wear protective gear to avoid breathing in this dust.

Some drywall products, especially those made in China, have raised health concerns due to hazardous chemicals like sulfur and strontium. These chemicals can cause corrosion and other issues. Additionally, some drywall products contain mold- and mildew-fighting agents that can trigger issues for people with sensitivities.

It’s important to note that not all drywall products are created equal, and U.S.-made drywall generally has lower levels of harmful chemicals. If you’re concerned about drywall safety, consult with a professional installer or manufacturer for more information.

Drywall vs Sheetrock: What’s the Difference?

Sheetrock is actually a brand name for drywall panels made by the USG Corporation (U.S. Gypsum Corporation). In other words, Sheetrock is a type of drywall!

The most commonly used drywall is the regular or “white board” type, which comes in 4-foot by 8-foot panels and ranges in thickness from 3/8-inch to 1-inch. This is the standard drywall you’ll find in most homes and buildings.

Types of Drywall

Regular Drywall (White Board):

Regular drywall is the most common type and is used in a variety of applications. Ideal for walls and ceilings in most rooms.

Moisture-Resistant Drywall (Green Board):

Designed for areas with high humidity, moisture-resistant drywall is perfect for bathrooms, kitchens, and laundry rooms. It has a green coating that makes it more resistant to moisture compared to regular drywall.

Mold-Resistant Drywall:

This type of drywall is treated with special chemicals to resist mold growth. Ideal for use in areas prone to dampness, such as basements and bathrooms.

Fire-Resistant Drywall (Type X):

Fire-resistant drywall contains fiberglass to increase its resistance to fire. People commonly use it in garages, apartment buildings, and other areas where fire resistance is critical.

Soundproof Drywall:

Soundproof drywall is designed to reduce noise transmission between rooms. Combining layers of gypsum board with polymers enhances its soundproofing qualities.

Paperless Drywall:

Instead of the traditional paper facing, paperless drywall has a fiberglass surface, making it more resistant to mold and water damage.

Eco-Friendly Drywall:

Made from recycled materials, eco-friendly drywall is a sustainable option for environmentally conscious builders.

What is Texturing Drywall?

Drywall texturing involves adding a special finish to drywall to change its appearance or conceal imperfections. It adds visual interest to walls and ceilings and people often use it in home and commercial construction.

Here are some common drywall texture types:

  1. Smooth Finish: This is a simple, flat, and smooth finish with no texture. Modern or minimalist designs often use it.
  2. Orange Peel: Orange peel drywall texture resembles the skin of an orange. A thin layer of drywall mud is sprayed using a special spray gun to create it. It provides a subtle texture and is easy to clean.
  3. Knockdown texture is made by spraying drywall mud on the surface. Then, it is smoothed with a trowel or knife to create a flat, textured appearance. It is often compared to stucco.
  4. Popcorn: Popcorn drywall texture looks bumpy like cottage cheese and is used on ceilings to hide imperfections and reduce noise. It is applied using a spray-on technique.
  5. Sand Swirl: This texture involves applying a thin layer of sand-based drywall mud and using a brush to create a swirling pattern. It adds a decorative, patterned look to walls and ceilings.
  6. Skip Trowel: This texture is achieved by applying a thin layer of drywall mud with a trowel and then skimming over it lightly, creating a skip pattern with peaks and valleys. It provides a rustic, hand-finished look.
  7. Slap Brush: This texture involves applying drywall mud and then “slapping” it with a brush to create a raised, uneven texture. It can create a unique, decorative effect.
  8. Hawk and Trowel: This texture uses a hawk (a flat board with a handle) and a trowel to apply and shape the drywall mud, creating a hand-crafted, artisan look with various patterns and thicknesses.

Various textures can alter how a room looks, adding character and style while hiding minor flaws on surfaces.

Benefits of Drywall


Drywall is a cheap building material that is a good option for both homes and businesses. It provides an excellent finish at a lower cost compared to other materials like plaster.

Easy Installation:

One of the main advantages of drywall is its ease of installation. Drywall panels have a lightweight construction and workers can quickly cut them to size, screw them, or nail them to the wall framing. This speeds up the construction process significantly.

Fire Resistance:

Drywall is fire-resistant, providing an added layer of safety to buildings. This is especially important in residential construction, where fire safety is a primary concern.

Energy Efficiency:

Drywall contributes to the energy efficiency of buildings by providing a barrier that helps maintain indoor temperatures. This can lead to lower heating and cooling costs.

Sound Insulation:

Drywall offers good sound insulation properties, reducing the transmission of noise between rooms. Specialized soundproof drywall can further enhance this benefit.

Aesthetic Appeal:

Drywall creates a smooth, clean surface that you can paint or wallpaper to match any interior design. It can also be textured to create unique finishes.


Drywall’s versatility allows it to be used for walls, ceilings, arches, and shelves. Its versatility makes it a popular choice for builders and designers.

Mold and Moisture Resistance:

You can protect damp and humid areas with moisture-resistant and mold-resistant drywall options. This helps prevent mold growth and prolongs the life of the walls.

Drywall Installation Process

Planning and Preparation:

Before starting the installation, it’s crucial to plan the layout and gather all necessary materials and tools. Measure the area to determine how many drywall panels you need. Make sure you have drywall screws, joint compound, drywall tape, a utility knife, a drywall saw, and a T-square.

Cutting the Drywall:

Drywall panels are usually 4×8 feet in size but can be cut to fit the dimensions of the room. Use a T-square and utility knife to score and snap the drywall to the required size.

Hanging the Drywall:

Start by attaching the drywall panels to the ceiling before moving to the walls. Use drywall screws or nails to secure the panels to the framing. Make sure to drive the screws or nails just below the surface of the drywall without breaking the paper facing.

Taping and Mudding:

Once all the panels are in place, it’s time to hide drywall seams. Apply drywall tape along the seams and cover it with a layer of joint compound (mud). Use a drywall knife to smooth the compound and let it dry. Add more layers of joint compound if required, ensuring to sand in between each layer to attain a sleek finish.

Sanding and Finishing:

After the final coat of joint compound is dry, sand the surface to create a smooth, even finish. Be careful not to sand too much, as this can damage the drywall. Once you complete sanding, the drywall is ready for priming and painting.

Drywall Maintenance and Repair

Routine Maintenance:

Drywall requires minimal maintenance. Regularly inspect for any signs of damage or wear, such as cracks or dents. You can easily repair these with joint compound and a little sanding.

Repairing Small Holes and Cracks:

For small holes and cracks, use a putty knife to fill the area with joint compound. Allow it to dry, then sand it smooth. Apply a second coat if necessary and sand again before painting.

Repairing Large Holes:

Large holes require a patch. Cut a piece of drywall slightly larger than the hole and secure it with drywall screws. Apply joint compound around the edges, cover with drywall tape, and add more joint compound. Sand the area smooth once it’s dry.

Dealing with Water Damage:

If drywall gets wet, it can become soft and discolored. You can cut out the affected area in cases of minor water damage and replace it with a new piece of drywall. For extensive damage, it may be necessary to replace entire sections of drywall.

Common Drywall Issues and Solutions


Cracks on drywall can appear because of settling of the building or temperature changes. These can be repaired with joint compound and drywall tape. If cracks are recurring, it might be necessary to investigate the structural integrity of the building.

Nail Pops:

Nail pops occur when the drywall moves, causing nails to push out. You can fix these by driving the nail back in and covering it with joint compound.

Water Damage:

Water damage can lead to mold growth and weakening of the drywall. Addressing the source of the water leak and replacing the damaged drywall is essential.


Mold can develop on drywall in damp environments. Mold-resistant drywall can stop mold growth, but if mold appears, clean it with a mold remover. The affected drywall may need to be replaced.
