Houston’s climate is tough on concrete—high humidity, heavy rains, heat, and year-round moisture movement all create conditions where coatings are more likely to fail. That’s why the warranty behind your garage floor coating matters as much as the system itself. Unfortunately, many warranties in the Houston market are written in ways that quietly limit protection.
Garage Floor Coating of Houston breaks down the most common warranty pitfalls homeowners should watch for.
Moisture Thresholds: The Loophole Most Installers Don’t Explain
Many contractors promote long warranties but exclude moisture using numbers like 3 lbs or 6 lbs MVER, or Tramex readings homeowners never see documented. These limits sound scientific, but they serve one purpose: to void the warranty when moisture causes a failure.
In Houston’s humid climate, moisture vapor is constant. If a coating peels or blisters, installers often take a reading afterward, point to a high number, and claim the warranty is void.
The Install-Day Upsell: A Common Gulf Coast Tactic
Another common tactic is the day-of “moisture discovery.” Once the slab is ground, the installer claims they’ve found unexpected moisture and pushes an expensive primer upgrade.
But moisture in Houston concrete is never unexpected.
That’s why we include moisture mitigation automatically in every garage floor coating system we install. No surprise charges, and no technical excuses later.
Tire Staining: The Hidden Clause No One Mentions
Plasticizer migration—permanent tire staining—is extremely common in high-heat markets like Houston. Many thin epoxies, 1-day systems, and entry-level polyaspartics don’t resist it, so installers simply exclude tire staining in the fine print.
Our multi-layer systems use 100% solids materials, a full-broadcast flake layer, and two polyaspartic clear coats, engineered to resist tire staining in Texas heat.
How to Spot a Warranty That Actually Protects You
Before choosing any contractor, make sure the warranty:
- covers all moisture-related issues
- includes moisture mitigation on every job
- does not exclude tire staining
- covers both materials and labor
- is supported by full Technical Data Sheets
If any part of this list is missing, the warranty likely protects the installer—not you.
