Mold Remediation Certification Practice Exam – Prep, Study Guide & Practice Test

Porous materials are defined by their ability to absorb moisture easily due to the presence of numerous small pores or voids within their structure. This characteristic allows them to take in liquids and gases, often leading to a higher risk of mold growth if the material remains damp. The presence of these pores means that porous materials are not solid and impenetrable; rather, they are often permeated with air spaces that can retain moisture.

While other materials may claim to be chemically inert or not retain moisture, this does not define the essence of porosity. Solid and impenetrable materials do not have the inherent characteristics of porosity, and therefore, do not readily absorb moisture. Understanding these properties is crucial in mold remediation, as it informs how different materials should be treated to prevent mold growth.
