Kitchen Performance Standards

Heat and Chemical Protection

Polyurea can handle steady heat up to 300°F and short bursts up to 350°F. Tests show it holds up through more than 10,000 exposure cycles across a pH range of 1–14. This means it stands strong against tough sanitizers, oil spills, acidic ingredients, and high-pressure cleaning methods. Its durability ensures low maintenance and long-lasting performance.

Maintenance Requirements

Daily sweeping and mopping with pH-neutral cleaners are recommended. Every three months, pressure washing at 900–1,200 PSI with a 50/50 water-vinegar mix is enough to keep it in good condition. High-traffic areas should be professionally inspected to catch early signs of wear, though recoating is typically only needed every 5–7 years in heavily used spaces. This maintenance plan can save about $1.50–$2.00 per square foot annually compared to traditional epoxy systems.

Polyurea vs. Epoxy Properties

When compared to epoxy, polyurea stands out in several key areas. For instance, a Coeur d’Alene hotel kitchen reported no floor repairs over four years, even with heavy equipment loads of up to 800 pounds.

Here’s a quick comparison of their properties:

Property	Polyurea	Epoxy
Temperature Range	-40°F to 250°F	-20°F to 150°F
Tensile Strength	3,500–5,000 psi	1,500–3,000 psi
Chemical Resistance	Handles strong cleaners	Breaks down with harsh chemicals
Installation Downtime	24 hours	3–7 days
Surface Smoothness	<5 RA µin	15–20 RA µin

Polyurea’s flexibility, with an elongation range of 300%–400%, helps it resist cracking during rapid temperature changes. Tests show it can handle over 500 cycles of temperature swings between -20°F and 250°F. Its fast curing time also reduces downtime significantly. For example, a Post Falls bakery avoided around $12,000 in lost revenue by resuming operations just 24 hours after installation.
