Berger-Seidle Green Star is a breakthrough two-component water-based hardwood floor finish engineered for professionals who want top performance without health risks. Traditional 2K finishes rely on isocyanate crosslinkers, which are hazardous, carcinogenic, and known to cause sensitivity reactions among flooring installers. Green Star uses a non-isocyanate hardening technology—a completely different chemistry that hardens without crosslinking—eliminating the common respiratory and skin-allergy issues associated with standard Part B hardeners.
 
This advanced technology also solves the biggest drawback of typical 2-component finishes: extremely short pot life. Products like Bona Traffic HD offer only about two hours of workable time after Part A and Part B are mixed. In contrast, Green Star remains perfectly smooth, consistent, and usable for an outstanding 18 hours, allowing you to mix in the afternoon and continue using leftovers the next day.
 
Despite being safer and easier to work with, Green Star still delivers elite commercial durability, excellent chemical and abrasion resistance, and crystal-clear appearance for both rolling and T-bar applications. It is also approved for sports flooring, meeting strict anti-slip requirements for basketball courts, gymnasiums, and performance surfaces where traction matters.
