Why Rubberized Coating Fails on Open Parking Decks — And Why PU is the Smarter Choice

Open parking decks are among the most exposed and high-impact areas of any structure. They face harsh weather, constant vehicle traffic, and chemical spills — all of which can easily break down a poor-quality surface coating.
Many property owners and contractors initially turn to rubberized coatings for waterproofing, hoping for a quick and cost-effective solution. But in exposed parking decks, these coatings often fail faster than expected — leading to recurring damage, costly repairs, and frustrated users.
So, what’s the smarter alternative? Polyurethane (PU) waterproofing.
The Problem with Rubberized Coating PU for Parking Decks
Rubberized coatings are designed to be flexible and water-resistant — but that doesn’t mean they’re suitable for everything. When applied to open parking decks, they show several weaknesses:
Common Issues with Rubberized Coatings:
Soft surface that wears out quickly under tire traffic
Low UV resistance, which leads to cracking, fading, and brittleness
Poor adhesion under constant movement and temperature shifts
Easily damaged by oil, fuel, and other chemicals
Not designed for heavy loads or long-term exposure
In short: Rubberized coatings aren’t built to survive the punishing conditions of open parking decks.
Why PU Waterproofing is the Smarter Choice
Liquid-applied Polyurethane (PU) is specifically engineered for high-traffic, exposed environments like rooftop and podium parking areas. It forms a durable, elastic membrane that moves with the structure while providing long-lasting protection.
PU Waterproofing Advantages:
High flexibility – Adapts to structural movement and thermal expansion
Strong UV resistance – Maintains integrity even under full sun
Abrasion resistant – Built for constant tire traffic
Chemical resistant – Withstands oils, fuel, and detergents
Seamless application – No joints or overlaps to leak or fail
Longer lifespan – Fewer reapplications, lower long-term costs
PU systems are designed to endure real-world conditions, making them ideal for the heavy use and exposure of open parking decks. PU for Parking Decks
Think Long-Term, Not Just Low Cost
Rubberized coating might seem like the cheaper option, but its performance doesn’t last. In fact, frequent damage and reapplications can end up costing more over time. Polyurethane, on the other hand, offers reliable protection for years, with minimal maintenance.
You’re not just coating a floor — you’re protecting an asset.
