What Is Moisture-Resistant Drywall?

Moisture-resistant drywall is a specialized type of drywall designed to handle areas prone to humidity and occasional water exposure. It is often called green board or mold-resistant drywall because of its green-colored paper facing and enhanced properties.


We use this material in spaces like bathrooms, kitchens, and laundry rooms where moisture levels are higher than usual. Its core and paper are treated to resist moisture absorption, reducing the risk of damage and mold growth.


The key benefits of moisture-resistant drywall include:


  • Increased durability in damp environments
  • Better mold and mildew resistance
  • Longer lifespan compared to regular drywall


While it is more resistant to moisture, this drywall is not waterproof. It is meant to protect against humidity and occasional splashes, not constant water immersion.


At Long Beach Elite Drywall, we ensure proper installation to maximize its effectiveness. This includes careful measuring, cutting, and securing with screws, followed by finishing with joint compound for a smooth surface.


Using moisture-resistant drywall helps maintain the integrity and appearance of walls in moisture-prone areas, making it a smart investment for lasting quality.

Applications and Use Cases

Moisture-resistant drywall is essential where water exposure and humidity are common. It protects structural integrity and prevents mold growth by using specialized materials designed to handle damp conditions.

Residential Bathroom and Kitchen Projects

Bathrooms and kitchens are prime areas for moisture buildup due to showers, sinks, and cooking activities. We install moisture-resistant drywall to prevent water damage behind tiles and around fixtures.


This type of drywall typically includes a water-repellent core and a mold-resistant facing, ensuring long-term durability. It helps maintain a healthy indoor environment by reducing the risk of mildew and mold growth in frequently wet areas.


In kitchens, it is especially useful around backsplashes and under sinks. Our choice of materials ensures walls stay strong despite daily exposure to steam and occasional splashes.

Commercial Installations

High-traffic commercial spaces such as restaurants, gyms, and healthcare facilities require drywall that withstands constant moisture and cleaning processes. We provide moisture-resistant drywall that meets building codes specific to these environments.


This drywall type supports sanitation needs and resists deterioration caused by frequent washdowns. In institutions, such as hospitals, it also helps prevent mold-related health issues by maintaining stable wall conditions.


We tailor installations to comply with regulations and provide durable, safe interiors that last despite challenging humidity levels and usage patterns.

Solutions for High-Humidity Areas

Basements often face moisture infiltration through the foundation and poor ventilation. We recommend moisture-resistant drywall as a preventative barrier to protect framing and insulation.



Using this drywall minimizes risks of water damage during seasonal dampness and reduces mold growth potential. It’s particularly important in unfinished or partially finished basements where humidity control is difficult.


Our installations include sealing joints and applying moisture barriers where needed, ensuring protection against both visible and hidden moisture threats in spaces prone to dampness.
