Drywall is essential to interior construction, commonly used in homes, offices, and commercial buildings. However, there are several misconceptions about drywall that people still believe and spread. These misconceptions can lead to poor decisions and incorrect assumptions about the material. 

This blog will uncover the truth behind the most common drywall misconceptions.

Misconception 1: Drywall Is Waterproof

One of the most common misconceptions about drywall is that it is waterproof. This is not true. Drywall is made of gypsum, a porous material that absorbs moisture quickly. If drywall is exposed to water for extended periods, it will disintegrate and lose its structural integrity. This can contribute to mold growth, which can be hazardous to your health.

To prevent water damage, use water-resistant drywall in areas prone to moisture, like bathrooms and kitchens. Additionally, it is crucial to address any water leaks or damage immediately to prevent further damage to the drywall.

Misconception 2: Drywall Is Fireproof

Another common misconception about drywall is that it is fireproof. While drywall is fire-resistant, it is not fireproof. It can withstand fire for a limited time but eventually break down and lose its structural integrity. When exposed to fire, the gypsum in drywall releases water vapor, which helps slow the spread of flames. However, this effect is temporary, and the drywall will eventually break.

To increase drywall fire resistance, manufacturers add materials like fiberglass to the gypsum core. These materials help slow the spread of flames and give you enough time to evacuate the building.

Misconception 3: All Drywall Is the Same

Not all drywall is the same. Different types of drywall are designed for specific applications. For example, there is standard drywall, which is used for most interior walls and ceilings. There is also moisture-resistant drywall intended for use in areas prone to moisture. Like banally, fire-resistant drywall is designed to slow the spread of flames in a fire.

Choosing the correct type of drywall for your project is essential to ensure it performs as intended. Using the wrong drywall type can lead to mold growth, water damage, and fire hazards.

Misconception 4: Drywall Is Easy to Install

While it may seem straightforward, installing drywall is a skilled trade that requires enough practice and experience. Proper installation ensures the drywall is structurally sound and looks good. Improper installation can lead to more significant problems, including bulging, cracking, and uneven seams.

Hiring a professional drywall installer is recommended to ensure the job is done correctly. A professional installer will have the knowledge, experience, and tools to complete the task efficiently and effectively.

Misconception 5: Drywall Will Last Forever

Drywall is not a permanent material and will eventually need to be replaced. Over time, drywall can develop cracks, bulges, and other structural issues, compromising its integrity. Additionally, drywall can become discolored and stained from exposure to sunlight, smoke, and other environmental factors.

The lifespan of drywall depends on several factors, like the quality of the drywall installation, the type of drywall used, and the conditions in which it is exposed. However, drywall can last up to 30 years with proper maintenance and care.


Drywall is a versatile and essential material in interior construction, but several things must be clarified. Drywall is not waterproof, fireproof, or easy to install, and it is not a permanent material. Choosing the correct type of drywall for your project is crucial, and hiring a professional installer ensures the job is done correctly.
