GarageFloorCoating.com has announced its Lifetime Moisture Warranty to provide coverage where most warranties do not, covering the leading cause of garage floor coating failure in the industry.
For more than 30 years, GarageFloorCoating.com has been a pioneer in residential concrete coatings, developing the decorative flake broadcast system now widely used throughout the industry. Today the company serves homeowners nationwide, including Washington and Idaho through Garage Floor Coating Inland NW.
Typical one-day garage floor coating warranties exclude moisture vapor transmission or hydrostatic pressure. But our new warranty addresses one of the most misunderstood risks in residential concrete without hiding behind exclusions.
Moisture Isn’t Unexpected. It’s Concrete Science
Many homeowners hire a 1-day installer for their garage floor coating thinking they’ll get longterm protection for a low price. But most of these quick-fix installers ignore the biggest threat to a coating’s longevity: moisture.
Concrete slabs are porous and continuously transmit vapor due to:
- Capillary action
- Groundwater pressure
- Seasonal soil moving
These conditions occur constantly in every region, including the Inland Northwest.
Why Inland Northwest Homes Suffer from Slab Moisture
Homes throughout the Inland Northwest face a wide range of seasonal conditions that can introduce additional moisture beneath residential slabs. Snow accumulation, spring runoff, and rainfall can saturate surrounding soils and contribute to vapor pressure beneath concrete.
In many homes, especially those built before vapor barriers were consistently installed beneath slabs, moisture can migrate upward through the concrete.
Even when the garage floor appears dry, vapor pressure can build beneath coating systems.
The Leading Cause of Coating Failure
Many fast-install coating systems apply thin polyurea or polyaspartic coatings right on the concrete, skipping a moisture-mitigating primer. What comes next is predictable: discoloration, blistering, delamination, and adhesion breakdown.
But their warranties often exclude moisture-related failures once vapor emission thresholds are exceeded.
Garage Floor Coating Inland NW takes a fundamentally different approach. The leading cause of failure isn’t excluded. It’s covered.
