For many homeowners, the biggest risk to a garage floor coating is also the least understood: moisture beneath the slab. GarageFloorCoating.com is addressing that risk with the launch of its Lifetime Moisture Warranty.
Unlike typical one-day warranties that exclude vapor-related failures, this warranty is designed to account for them.
Founded in Arizona, GarageFloorCoating.com has been a pioneer in residential concrete coatings for more than 30 years and now serves homeowners across the country, including Maryland through Garage Floor Coatings of Maryland.
How Moisture Threatens Your Garage Floor
Some homeowners DIY their garage floor coating or hire a quick-fix installer because they want their concrete to look and function better. But most 1-day installers ignore the biggest threat to a coating’s longevity: moisture.
In many homes, especially older properties built before vapor barriers were commonly installed beneath slabs, moisture can migrate upward through the porous concrete.
That’s a recipe for coating failure when paired with Maryland conditions like:
- Humid weather
- Seasonal rainfall and groundwater movement
- Irrigation and landscape drainage
- Temperature swings that increase vapor pressure
Even when the garage floor appears dry, vapor pressure can build beneath coating systems.
What Most Companies Get Wrong
No matter how nice your coating looks on day one, it won’t last if moisture was not mitigated for. Vapor moving through the slab will inevitably lead to blistering, delamination, discoloration, and bond failure, and your garage floor will look even worse than before you had it coated.
Yet many fast-install companies apply thin polyurea or polyaspartic coatings directly to concrete, skipping any sort of moisture-mitigating primer. Their warranties often shift the risk back to the homeowner by excluding moisture once vapor levels rise.
We take a different approach. If moisture causes the failure, it should be covered.
