Urethane coatings are prized for their durability, flexibility, and chemical resistance—but choosing and applying them correctly is key to maximizing performance. Whether you’re sealing a concrete floor in a warehouse, hospital, or retail space, urethane can provide long-term protection with minimal maintenance when installed properly.
In this article, we’ll break down tips for selecting the right urethane system, how to prep surfaces effectively, and what to watch for during installation.
Water-based urethanes are ideal for interior, low-odor settings, while solvent-based versions deliver enhanced hardness and gloss for industrial or exterior use.
Ensure the concrete substrate is dry and meets the required CSP (Concrete Surface Profile), usually CSP 3 or higher for most urethane applications.
Use a compatible epoxy or urethane primer to promote adhesion and reduce pinholes on porous surfaces.
Follow manufacturer guidelines for mil thickness—typically 2–3 mils per coat. Applying too thick can cause bubbling or soft curing.
Avoid traffic before the full cure—usually 24–72 hours depending on the system. Fast-cure urethanes may allow quicker turnaround but require more precision during application.
Always mix part A and B fully and allow for the recommended induction time to ensure chemical activation.
In high-traffic or wet areas, incorporate aluminum oxide or quartz for added slip resistance.
Once installed, regular cleaning with pH-neutral products will help preserve gloss and performance over time.
