In Phoenix’s dry climate, homeowners might assume moisture isn’t a problem. But when it comes to garage floor protection, industry experts agree: starting with a moisture-mitigating epoxy floor coating is essential—especially before applying a polyurea or polyaspartic floor coating.
The Risks of Skipping Moisture Mitigation in Garage Floors
Many “1-day” coating companies in the Phoenix area promote fast turnarounds by applying fast-cure polyurea or polyaspartic floor coatings directly to concrete. But polyaspartics cure far too quickly to form a strong mechanical bond with the concrete slab. Without a slow-curing, moisture-mitigating coating as a primer, trapped moisture vapor can become a real problem.
This trapped vapor can lead to:
- Blistering and bubbling
- Delamination and peeling
- Voided warranties due to hydrostatic pressure
And while Phoenix may not experience as much humidity as coastal areas, moisture can still migrate through the concrete slab—especially after monsoon storms or during irrigation runoff.
What the Experts Say About Polyaspartic Floor Coating Systems
Respected manufacturers like Sika, Dur-A-Flex, and General Polymers all recommend epoxy primers before applying polyurea-polyaspartic floor coatings. Likewise, standards from ASTM International and ACI call for:
- Surface prep using CSP (Concrete Surface Profile) protocols
- Moisture testing before installation
- A 100%-solids, moisture-mitigating epoxy floor coating as a vapor barrier base
Skipping these steps just to finish in one day undermines the floor’s durability and shortchanges the customer.
