The Problem: Coatings That Peel, Crack, or Just Don’t Last
Tucson homeowners might expect their garage floors to hold up well in the desert heat—but many are surprised when their garage flooring starts peeling, bubbling, or even cracking within a year of installation. The issues may not be immediate, but they often show up soon after monsoon season or during major temperature swings.
And once they start, they only get worse.
The Cause: Moisture-Vapor Transmission You Can’t See
Here’s the surprising truth: even in dry climates like Tucson, moisture-vapor transmission (MVT) is a serious concern. Concrete slabs absorb moisture from underground sources like irrigation systems, groundwater, or seasonal humidity spikes. That moisture travels upward through the slab in vapor form, eventually hitting the surface—right where your coating is supposed to protect.
If that coating isn’t designed to block vapor:
- It can bubble or delaminate under pressure
- It might trap moisture, causing discoloration or surface damage
- In extreme heat, trapped vapor accelerates breakdown
The real problem is in the slab—and 1-day garage flooring systems do nothing to stop it.
“1-day” coating systems use fast-curing polyurea or polyaspartic coatings as both the base coat (the direct-to-concrete primer) and single topcoat. But in the presence of medium to high moisture, these coatings cure so quickly (< 1 hour) that they don’t have time to deeply penetrate the concrete slab. In addition, they go down very thinly (unlike a “high-build” epoxy). Consequently, they fail to form a true vapor barrier. 1-day coating system are a shortcut, speed over quality, and in Tucson’s unique climate, it’s a costly one.
The Solution: GFC Tucson’s 2-Day System With True Moisture Mitigation
GarageFloorCoating.com (Tucson) uses a 2-day installation garage flooring system specifically to solve this problem. It starts with a thick, direct-to-concrete layer of 100%-solids moisture-mitigating epoxy. The high-build coating penetrates slowly and deeply into the concrete and cures into a solid, moisture-blocking foundation. This base coat eliminates upward vapor transmission before it can cause damage. Into this base coat, we broadcast the customer-selected flake blend.
After curing overnight, we apply two separate layers of our 100%-solids polyaspartic topcoat (not just one!). The dual topcoats provide UV, impact, chemical and stain resistance, and long-lasting durability—even in Arizona heat.
Why it works:
- Epoxy base = true vapor barrier
- Proper cure time = full adhesion and moisture defense
- Dual polyaspartic topcoats = extreme protection from heat, wear, fading and hot-tire transfer
