Garage Floor Coating Myths: 5 Mistakes That Cause Floors to Fail

On Long Island, garages face humid summers, salty air, and icy winters that drag in road grime. A high-quality garage floor coating can protect against it all—but too many myths leave homeowners with floors that fail prematurely. Here’s the truth behind the most common misconceptions.

Myth #1: Moisture Isn’t an Issue in Coastal Garages

Reality: Even in coastal areas, moisture vapor rises through concrete slabs. Without a moisture-mitigating epoxy primer, coatings can bubble, peel, or delaminate. Every long-lasting garage floor coating starts with this essential layer.

Myth #2: Tire Marks Are Just a Cleaning Problem

Reality: Dark tire marks aren’t just dirt—they’re hot tire transfer. Heat softens weak coatings, letting plasticizers from the rubber and road contaminants embed in the surface. UV-stable polyaspartic topcoats prevent this breakdown, keeping floors clean and glossy.

Myth #3: Sunlight Doesn’t Impact Indoor Floors

Reality: Long Island garages often sit open for airflow or extra light. UV rays streaming in cause ordinary epoxy to yellow, fade, or chalk. A professional garage floor coating includes UV-stable polyaspartic topcoats that resist sun damage.

Myth #4: Thin Coatings Are Strong Enough

Reality: From bikes and beach gear to snow blowers and tool drops, Long Island garages are high-use spaces. Thin coatings chip and crack quickly. A full-flake broadcast sealed with dual polyaspartic layers ensures durability and impact resistance.

Myth #5: All Coatings Resist Salt and Chemicals

Reality: Road salt, ocean air, and garage spills like oil or cleaners break down low-grade coatings fast. Professional systems are engineered for chemical resistance, so your garage floor coating stands strong against both salt and stains.
