Why This is Important
Mold is a critical part of our environment, quietly helping to break down organic material that’s all around us.

What Makes Mold Grow on Concrete
When mold spores land on a concrete surface, they act as nourishment that enables bacteria and other particles to form a robust feast. This powerful blend then works its way deep into the concrete’s pores causing it to become degraded over time; creating an all-too inviting invitation for further airborne moisture and intrusion further moisture.
Concrete has an unfortunate affinity for moisture, allowing it to seep in and create a hospitable environment for mold. Poor drainage at the time of pouring or incorrect installation of a vapor barrier can also lead to this unwelcome growth – so taking every necessary precaution to to prevent mold growth on concrete, is key!
For mold to thrive, its ideal environment is one that’s shady and humid – like a concrete patio or walkway in dappled light. Sunlight and higher temperatures can inhibit the growth of mold spores always looking for moist areas to call home!
Mold or Efflorescence
With white mold growth ranging in various colors, it can be easy to both identify mold or spot the infamous black mold variety – but what about when something looks awfully similar to identify mold? Enter efflorescence. An alluring crystal formation that arises from moisture travelling through concrete, this phenomenon is somewhat of an enigma easily mistaken for white mold.
