Why Standard Drywall Fails in Louisiana’s Humidity

In most parts of the country, "Green Board" (moisture-resistant drywall) is a specialty product reserved strictly for the area directly behind a bathroom vanity. But here in Acadiana, we don't live in a "standard" climate.

In most parts of the country, “Green Board” (moisture-resistant drywall) is a specialty product reserved strictly for the area directly behind a bathroom vanity. But here in Acadiana, we don’t live in a “standard” climate.

Between our sweltering summers and damp winters, the air in Lafayette, Youngsville, and Broussard is often thick enough to feel. For your home’s walls, that humidity is a constant, invisible threat. At Patch Perfect, we often recommend upgrading to moisture-resistant or mold-resistant “Purple Board” for areas most contractors might overlook.

What Exactly is Green Board?

Standard drywall is essentially gypsum powder pressed between two sheets of paper. Because paper is an organic material, it acts as a food source for mold when it gets damp.

Green Board is treated with a specialized waxy coating on the paper facing and chemicals within the gypsum core that repel moisture. It is designed to handle high-humidity environments where regular drywall would eventually soften, sag, or grow mildew.

3 Places in Your Louisiana Home That Need an Upgrade

While the building code may only require moisture-resistant board in bathrooms, the Louisiana climate suggests otherwise:

1. The Laundry Room

2. The Garage & Mudroom

3. Kitchen Backsplashes & Near Sinks

The Patch Perfect Advantage: Precision and Protection

 When we perform a “Make Ready” or a full room refresh, we don’t just look at the holes in the wall—we look at the environment.

•Smart Material Selection: If we notice a room has poor ventilation or high humidity, we’ll suggest the right moisture-resistant board to prevent future repairs.

•Premium Finishing: We pair our high-end drywall work with Sherwin-Williams Emerald® or Duration® paints, which contain anti-microbial agents to further inhibit mold and mildew growth.

•24/7 Responsiveness: If you notice your walls feeling “soft” or see paint bubbling in a humid room, give us a call in Maurice or Breaux Bridge any time of day.
