Moisture is the number one cause of garage floor coating failure, and now, there’s finally a lifetime warranty covering it. GarageFloorCoating.com, widely recognized as one of the best garage floor coating companies in the nation for durability and performance, is proud to announce the launch of its Lifetime Moisture Warranty.
Moisture Is The Leading Cause of Garage Floor Coating Failure, Even in Arizona
Many homeowners assume moisture problems only affect humid climates. In reality, Arizona is actually one of the most challenging environments for garage floor coatings.
The concrete used in home garages is often extremely porous, and many houses in the region were built without adequate vapor barriers beneath the slab. This means moisture can migrate upward from the soil below.
But there are plenty of other factors that can increase vapor pressure, such as monsoon saturation, irrigation systems, extreme heat that accelerates vapor drive, and expansive clay soils.
Even if the garage floor surface appears dry, vapor pressure can build beneath a coating.
Many fast-install “one-day” systems apply thin polyurea or polyaspartic coatings directly to concrete, leading to inevitable blistering, discoloration, and adhesion breakdown. But then the installer excludes moisture-related failures from their warranty.
We think this is a terrible business practice. So we’re doing things differently.
Long-Term Performance Starts with Engineering
GarageFloorCoating.com’s system is designed to address vapor transmission through concrete slabs and includes:
- 100% solids moisture-mitigating epoxy primer
- Full broadcast decorative flake layer
- Two 100% solids polyaspartic clear coats
- 35+ mil total system thickness
The thick, moisture-mitigating primer is engineered to stop vapor transmission before it reaches the coating system, allowing us to offer a Lifetime Moisture Warranty with no emission thresholds or exclusions.
In Arizona, where monsoon seasons, irrigation, and porous slabs drive moisture through concrete, that protection makes all the difference.
