Across New Jersey, 1-day garage coating companies promise fast, flawless installations using polyurea or polyaspartic floor coatings. But beneath the slick marketing, there are critical details they don’t mention—especially when it comes to moisture mitigation. Let’s bust the biggest myths and share the facts every homeowner should know.
Myth: Polyaspartic Floor Coatings Don’t Need Epoxy Primers
Some companies claim polyurea-polyaspartic floor coatings bond directly to concrete without needing a primer.
Fact: Industry leaders like Sika, Dur-A-Flex, and General Polymers warn that polyurea and polyaspartics cure far too quickly to penetrate concrete pores. Without a moisture-mitigating coating, moisture vapor trapped beneath the surface leads to blistering, peeling, and delamination. The best practice is applying a slow-curing, 100%-solids, moisture-mitigating epoxy floor coating primer first—before polyaspartic floor coatings.
Myth: New Jersey’s Weather Doesn’t Create Moisture Problems
Fast-install companies often downplay New Jersey’s climate, saying you don’t need to worry about moisture issues.
Fact: New Jersey sees humid summers, wet springs, and coastal weather that saturates concrete slabs with ground moisture. As that moisture vapor migrates upward, it puts pressure against polyurea-polyaspartic floor coatings—leading to early failure. ASTM F3010 specifically calls for vapor barrier primers beneath resinous coatings to prevent this problem.
Myth: Warranties Always Cover Moisture Issues
Many 1-day companies advertise long warranties to build trust (e.g., “limited lifetime”).
Fact: Most of these warranties exclude moisture-related failures or set strict moisture tolerance limits that make claims nearly impossible. At Garage Floor Coating of New Jersey, our 2-day system includes moisture testing, surface preparation, and a 100%-solids moisture-mitigating coating primer. Only then do we apply our 100%-solids polyaspartic floor coatings—and we back our work with a real warranty that fully covers moisture-related failures.
