Long Island homeowners know the challenges of unpredictable weather—heavy rains, high humidity, and dramatic temperature swings. Yet many 1-day companies promote polyurea or polyaspartic floor coatings as a fast, durable solution. But industry experts warn this shortcut skips essential moisture mitigation—putting your garage floor at risk.
The Problem: Long Island’s Moisture Challenges
Whether it’s coastal humidity or seasonal rains, Long Island garages face constant moisture. Concrete naturally absorbs water from the ground, which migrates upward as moisture vapor. When installers skip the moisture-mitigating coating step and apply polyurea or polyaspartic floor coatings directly to concrete, you risk:
- Moisture vapor buildup leading to hydrostatic pressure that pushes up on the thin, poorly-penetrating primer coat
- Inevitable bubbling, peeling, and delamination over time
- Warranties that exclude moisture-related failures, leaving you unprotected
The Solution: Epoxy Primers for Moisture Mitigation
Manufacturers and industry experts agree: before using polyaspartic floor coatings, apply a 100%-solids, moisture-mitigating epoxy floor coating primer. This slow-curing layer penetrates deep into the concrete slab, providing a strong mechanical bond and blocking moisture vapor transmission—crucial in Long Island’s damp coastal climate.
The Proof: What Industry Standards Say
Top manufacturers like Sika, Dur-A-Flex, and General Polymers, as well as organizations like ASTM and ACI, recommend:
- Testing every slab for moisture
- Preparing surfaces to CSP standards
- Using epoxy vapor barrier primers before applying polyaspartic floor coatings
ASTM F3010 outlines exactly these steps to prevent early coating failure.
