Katy TX averages 50+ inches of rain a year. That moisture wicks through unsealed concrete slabs, creating ideal conditions for mold and mildew — in your garage, basement, or utility room. Left untreated, mold damages stored items, creates odors, and can affect air quality throughout your home.
What Is Concrete Mold?
Mold on concrete appears as black, green, or white fuzzy patches or a musty film. It thrives wherever moisture is present — condensation from the ground, water intrusion from cracks, or humidity. Concrete is porous, so it absorbs and holds moisture, making it a prime host. In the Houston climate, even a small moisture source can produce significant mold growth within days.
Why It Matters Before Epoxy
Applying epoxy over active mold is a recipe for delamination. Mold compromises the adhesion between concrete and coating, causing the floor to peel within months. More importantly, sealing mold beneath an impermeable coating without addressing the moisture source just moves the problem — it'll find another way out. We address the source first.
Our Process
- Moisture assessment — test concrete moisture vapor emission (MVE) and relative humidity
- Mold remediation — surface treatment and source identification
- Crack and joint sealing — stop water infiltration pathways
- Vapor barrier primer — penetrating epoxy primer rated for high-moisture slabs
- Full epoxy system — topcoat rated for Houston humidity and heat
