Poly Fix

Ultra-low viscosity polymer concrete repair binder

Poly Fix® is a robust, two-component, ultra-low viscosity hybrid polyurethane binder designed for concrete repair. Its consistency is akin to water, enabling it to effectively penetrate hairline cracks or, when combined with dry sand, to repair concrete spalls or control joints. Poly Fix® is also an excellent solution for healing and sealing deteriorated concrete surfaces. Notably, it contains no VOCs (Volatile Organic Compounds), aligning with environmental compliance.
