Choosing the Right Drywall for High-Humidity Areas in Spartanburg

Published March 20th, 2025 by Brown's Drywall Repair

Spartanburg's humid climate creates significant challenges for drywall in areas prone to moisture. Selecting the appropriate type of drywall is essential to avoid damage, prevent mold growth, and sidestep expensive repairs in high-humidity spaces. Homeowners in Spartanburg need to consider factors like moisture resistance, mold prevention, and durability when choosing drywall for bathrooms, kitchens, and basements. By understanding the options available and their specific benefits, Spartanburg residents can make informed decisions to protect their homes from humidity-related issues and maintain a healthy living environment.

Understanding Humidity Challenges in Spartanburg

Spartanburg's climate affects drywall in several ways:

  • High year-round humidity levels
  • Frequent summer rainfall
  • Temperature swings causing condensation
  • Increased risk of mold and mildew growth

Types of Moisture-Resistant Drywall

Several drywall options are designed for high-humidity areas:

  1. Green Board
  2. Purple Board
  3. Cement Board
  4. Paperless Drywall
  5. Mold-Resistant Drywall

1. Green Board

Green board is a popular choice for moderately humid areas:

  • Water-resistant core and paper facing
  • Suitable for bathrooms and laundry rooms
  • Not recommended for areas with direct water exposure

2. Purple Board

Purple board offers enhanced moisture and mold resistance:

  • More moisture-resistant than green board
  • Ideal for basements and garages
  • Can withstand higher humidity levels

3. Cement Board

Cement board is the most water-resistant option:

  • Made from cement and reinforcing fibers
  • Perfect for shower areas and exteriors
  • Highly durable but more expensive

4. Paperless Drywall

Paperless drywall eliminates paper facing, reducing mold risk:

  • Fiberglass mat instead of paper
  • Excellent for high-humidity areas
  • More resistant to moisture damage

5. Mold-Resistant Drywall

Specifically designed to prevent mold growth:

  • Contains antimicrobial additives
  • Suitable for kitchens and bathrooms
  • Helps maintain healthier indoor air quality

  1. Use moisture-resistant joint compound

  4. Seal all joints and seams carefully
  5. Allow for expansion and contraction

Maintenance of Moisture-Resistant Drywall

To maintain your drywall's moisture resistance:
