What is Green Board Drywall?
Greenboard drywall is a type of gypsum-based drywall wrapped in green paper on one side, coated in wax that makes it more resistant to moisture than traditional drywall. It was introduced in the 1960s as a direct tile backer for water-logged areas like showers and bathtubs but has since been replaced by cement backer board.
However, it still has several beneficial applications today, particularly in high-moisture areas such as bathrooms and kitchens. The key difference between drywall and greenboard is the moisture-resistant green paper covering, which makes it more suitable for use in damp environments.
The Properties of Green Board
If you’re looking for a drywall product that can withstand moisture, then Green Board may be the perfect solution for you. This type of drywall is specially designed to be moisture-resistant, making it an ideal choice for high-humidity areas like bathrooms and kitchens. Let’s take a closer look at the properties of Green Board.
1. Gypsum Core
Greenboard has a gypsum core, just like regular drywall. However, it’s covered with green paper on one side instead of white paper.
2. Moisture-Resistant
The main advantage of Greenboard is that it’s more moisture-resistant than regular drywall. The green paper covering is coated in wax, making it more resistant to water damage.
3. Not Waterproof
While Greenboard is more resistant to moisture than regular drywall, it’s important to note that it’s not waterproof. It’s still susceptible to water damage if exposed to standing water for an extended period.
4. Ideal for High-Moisture Areas
Greenboard is ideal for use in high-moisture areas like bathrooms and kitchens. It’s a popular choice for walls and ceilings in these areas because it’s more resistant to moisture than regular drywall.
5. Easy to Cut and Install
Greenboard, a type of drywall, is easy to cut and install, making it a popular choice for DIY enthusiasts and contractors alike. Its relatively lightweight and manageable size allow for straightforward installation, while its water-resistant properties make it a practical option for bathrooms, kitchens, and other areas prone to moisture.
What Is Green Board Used For
Green board is commonly used in bathroom walls and ceilings due to its moisture-resistant properties. Bathrooms are prone to high humidity and moisture, which can lead to the growth of mold and mildew. Using Green board in these areas can help prevent water damage and keep the walls and ceilings in good condition.
1. Kitchen Backsplash
Another common use for Green board is as a backsplash in the kitchen. Similar to bathrooms, kitchens are also prone to moisture and humidity due to cooking and cleaning activities. Using Green board as a backsplash can help protect the walls from water damage and make cleaning easier.
2. Laundry Rooms
Laundry rooms are another area where Green board can be used. These areas are often humid and prone to water spills, which can damage regular drywall. Green board can help prevent water damage and keep the walls in good condition.
3. Basements
Basements are known to be damp and humid, making them a perfect candidate for Green board. Using Green board in the basement can help prevent moisture damage and mold growth, which can be harmful to your health.

FAQ About Greenboard Drywall
What is the difference between drywall and green board?
The main difference between drywall and green board is the waxy coating on the paper facing of green board, which makes it resistant to mold and water. Otherwise, green board is identical to standard drywall and is used for walls in areas that are damp but not continuously wet, such as bathrooms or kitchens. The term “green board” is commonly used by trade professionals to refer to this type of moisture-resistant drywall.
Can you use greenboard in a shower?
While greenboard can be used in bathrooms and other areas, it should not be used as a tile backer in a shower or tub surround. It is suitable for use in areas not subject to direct water exposure, such as bathroom walls and ceilings, as well as areas of noncontinuous high humidity. However, for areas that will be continuously exposed to water, such as shower stalls, it is recommended to use cement board or other waterproof materials.
Can you paint directly on green board?
Yes, you can paint directly on green board, but it is recommended to apply a primer first. The paper facing of green board is specially designed to resist moisture, but it can be difficult for paint to adhere to. Applying a primer before painting will ensure that the paint adheres properly to the surface and provides a smooth finish. Additionally, it is important to make sure that the green board is completely dry and free of dust or debris before painting to ensure the best results.
Can you cut green board with a utility knife?
Yes, you can cut green board with a utility knife. However, it is important to use a sharp blade and make several passes to avoid damaging the edges or creating jagged cuts. Additionally, it is recommended to use a straight edge or T-square to guide the knife and ensure a straight cut. For larger cuts or more precise cuts, it may be necessary to use a saw or other cutting tool. Always wear appropriate safety gear, such as gloves and eye protection, when cutting green board or any other building material.
Conclusion
Finally, greenboard drywall is a moisture-resistant building material commonly used in areas that may be subject to high humidity, such as bathrooms and kitchens. While it is similar to standard drywall, the key difference is the waxy coating on the paper facing that provides resistance to mold and water. Greenboard can be cut and painted with proper techniques and tools, but it is important to keep in mind its limitations.
It should not be used as a tile backer in shower or tub surrounds and should be reserved for areas not subject to direct water exposure. Understanding what is greenboard drywall and its properties can help you make informed decisions when planning and executing your building projects.
