ROUND 3: PERFORMANCE FACTORS
When it comes to commercial roof coatings, moisture levels aren’t just a technical detail – they’re the difference between a 20-year solution and a 2-year disaster. Every year, hundreds of coating projects fail prematurely because moisture specifications get treated like optional suggestions rather than critical requirements.
While manufacturers tout advanced formulations and space-age polymers, the fundamental challenge remains unchanged: managing moisture during application. Let’s examine how our coating contenders perform when moisture enters the equation.
Polyurethane Performance Under Moisture Stress
Polyurethane coatings demand extremely strict moisture control during application. Surface moisture must typically remain below 12%, with relative humidity under 85% – conditions that prove challenging in many climates.
Even minor deviations from moisture specifications can trigger devastating consequences. When moisture exceeds limits during curing, polyurethane coatings can develop microscopic pinholes that compromise the entire system’s integrity.
The coating’s chemical reaction with excessive moisture creates weak spots that expand over time. What starts as invisible damage can lead to complete coating failure within 2-3 years.
While polyurethane performs admirably in controlled conditions, its extreme moisture sensitivity creates significant real-world limitations.
Silicone Performance Under Moisture Stress
Silicone coatings demonstrate remarkable resilience to moisture variation during application. They can be successfully installed with surface moisture levels up to 20% – nearly double polyurethane’s tolerance.
This forgiving nature means silicone maintains its protective properties even when moisture conditions aren’t perfect. The coating forms strong bonds despite humidity fluctuations that would compromise other systems.
Most importantly, silicone’s moisture tolerance translates to consistent long-term performance. The coating maintains its protective properties even after extended exposure to standing water and high humidity.
