What is a potential risk of improper drywall finishing?

Increased fire hazard
Mold growth due to moisture retention
Warping of drywall sheets
Improper alignment of seams

The correct answer is: Mold growth due to moisture retention

Improper drywall finishing can lead to mold growth due to moisture retention, making it a significant risk. When drywall is not finished correctly, gaps, cracks, and uneven surfaces can trap moisture. This moisture creates an ideal environment for mold spores to thrive, especially in areas with high humidity or where water exposure occurs. Mold can pose serious health risks, including respiratory issues and allergic reactions, and can compromise the integrity of the building structure. Proper finishing techniques, including sealing seams and ensuring a smooth, even application of joint compound, are essential to minimize moisture retention and promote healthy indoor air quality. This highlights the importance of following correct drywall finishing practices to prevent such health hazards.
