Hardener (B12) for Supra A.T. Satin | Catalyst for 2-Component Floor Finish Systems

The Hardener (B12) for Supra A.T. Satin is a specialized catalyst designed to be mixed with Loba Supra A.T. Satin, creating a durable two-component waterborne floor finish system. Once combined, the hardener enhances chemical resistance, abrasion durability, and overall performance, making it ideal for high-traffic commercial and residential wood flooring applications.

This hardener is essential for activating the cross-linking properties of the Supra A.T. Satin, ensuring maximum adhesion, wear resistance, and long-term finish clarity without compromising the satin sheen.

Key Features:

• Improved Durability – Increases scratch and chemical resistance of the floor finish

• Optimized Cross-Linking – Enhances performance for high-wear environments

• Easy Mixing Ratio – 1-part hardener to 10-parts finish for consistent results

• Clear, Non-Yellowing – Maintains the natural look of wood with satin appearance

• Fast Reactivity – Provides reliable drying and curing times after activation

Application:

• Mix thoroughly with Loba Supra A.T. Satin immediately before use

• Pot life after mixing is typically 2–4 hours; only mix what can be used within that time

• Apply using recommended applicators such as rollers or T-bars

• Suitable for hardwood floors in residential homes, schools, offices, and retail spaces

Pro Tip:
Only mix the amount of finish you plan to use immediately—once activated with Hardener B12, the working time is limited. Label your container with the mix time to track pot life during application.
