What type of surfaces are often more absorbent for mold growth?

Porous surfaces, such as wood or drywall, are often more absorbent for mold growth because they have a structure that allows moisture to penetrate and become trapped inside. Mold requires moisture to thrive, and porous materials retain water more effectively than non-porous materials. When these surfaces absorb excess humidity or water from spills, leaks, or high humidity conditions, they provide an ideal environment for mold spores to colonize and grow.

In contrast, non-porous surfaces like metal and glass do not absorb moisture to the same extent, making them less conducive to mold growth. While concrete and brick can absorb some moisture, they are typically less susceptible to mold growth compared to wood or drywall, as they often have a dense structure and can dry out more effectively. Plastic and vinyl surfaces are also not conducive to mold growth since they do not retain moisture, which is a critical factor for mold development. Thus, porous surfaces are unequivocally linked to higher susceptibility to mold.
