What’s Lurking Below Your Garage Flooring? Understanding Moisture-Vapor Transmission
In Phoenix, dry air might lead you to assume moisture problems are off the table—but when it comes to garage flooring, the real concern often lies beneath the surface. Concrete slabs naturally absorb and release water vapor from the ground below. This process, known as moisture-vapor transmission (MVT), can quietly damage flooring systems from within. MVT is particularly problematic in garage environments. The pressure from vapor trying to escape upward can break down coatings, cause bubbling or peeling, and even lead to staining or mold growth. That’s where GFC’s expertise—and product design—comes into play.
How GFC’s 2-Day Garage Flooring System Stops Moisture Damage Cold
GarageFloorCoating.com (Phoenix) installs a 2-day garage flooring system specifically engineered to combat MVT in Arizona’s unique conditions. The key is in the base layer: GFC uses a 100%-solids, moisture-mitigating epoxy as its base (primer) coat, known for its thick application and ability to bond deeply with concrete. This base layer forms a dense barrier that halts vapor in its tracks—an essential step for long-term moisture mitigation.
Once the moisture-mitigating epoxy cures (and the chosen flake blend is broadcast), we return on day 2 to apply two 100%-solids polyaspartic topcoats. These dual layers provide additional durability and stain, chemical, impact and UV protection. The result? A tough, beautiful finish that doesn’t just sit on your concrete—it shields it.
Why GFC’s 2-day system works:
- 100%-solids moisture-mitigating epoxy base: Excellent adhesion and resistance to hydrostatic pressure.
- Cures slowly and properly overnight, ensuring deep penetration allowing the vapor barrier to form completely.
- Dual 100%-solids polyaspartic topcoats add durability without compromising the moisture block.
Why 1-Day Garage Flooring Systems Fall Short in Phoenix
Some companies in the Phoenix area offer “1-day” garage flooring systems that use a polyurea or polyaspartic as both the base coat and single top coat. While this speeds up installation, it skips a crucial step. A polyurea or polyaspartic is a lousy base coat; it doesn’t adhere to concrete as effectively as a moisture-mitigating epoxy and lacks the thickness needed for proper moisture mitigation. Fast doesn’t mean better—especially when you’re battling long-term moisture damage from below.
