Most homeowners assume a “lifetime warranty” means peace of mind. But in the garage floor coating industry, the fine print often tells a very different story. At GarageFloorCoating.com, we’re raising a red flag: Many warranties in this industry are deliberately structured to fail you the moment moisture becomes involved.
Moisture is the #1 cause of coating failure in North America, and yet most installers design their warranties specifically to avoid covering it. Here’s what every homeowner needs to know before signing any contract.
How Moisture Loopholes Undermine Most Garage Floor Coating Warranties
Across the industry, installers promote impressive-sounding warranties: “20-year,” “limited lifetime,” even “lifetime.” But they hide the truth beneath pages of exclusions. One of the biggest traps? Moisture thresholds, often written as “3 lbs MVER,” “6 lbs MVER,” or “5.0+ on a Tramex meter.”
These numbers are not scientific safeguards. They are escape mechanisms.
Homeowners don’t own moisture meters, don’t understand MVER, and have zero control over how or when testing is performed. Worse, installers rarely document tests prior to installation. So when a coating fails—often because vapor pressure surged and pushed the coating off the concrete—the installer simply takes a reading, points to a high number, and declares the warranty void.
GarageFloorCoating.com rejects these tactics. Our garage floor coatings include a proprietary moisture-mitigation vapor barrier primer on every single installation, with no exclusions and no fine-print surprises.
The Problem With “Surprise Moisture Fees” on Install Day
Another widespread tactic is the unexpected moisture-related upcharge that typically occurs the day of installation when diamond grinding has completed. Contractors grind the floor, claim they’ve “discovered” moisture, and pressure homeowners into costly add-on fees well after the initial quote that was agreed upon has been completed.
But moisture in concrete isn’t a surprise; it’s inevitable.
These charges are not technical requirements; they’re strategic upsells that pave the way for future warranty denial. At GarageFloorCoating.com, we refuse to play that game. Every system from residential garages to heavy-duty commercial spaces includes moisture mitigation automatically, without last-minute price changes.
