Bona R540 is a high-performance one-component reactive polyurethane primer designed for seamless compatibility with the entire Bona flooring system.

This advanced moisture barrier and primer excels in both absorbent and non-absorbent floor applications, creating a solid foundation for your flooring projects.

Imagine the peace of mind that comes with knowing your floors are safeguarded by a robust moisture shield, capable of withstanding up to 5 CM% or 95% relative humidity.

The primer's versatility shines through as it effectively waterproofs cement screeds and concrete floors, ensuring long-lasting protection against moisture infiltration.

Its unique formulation not only serves as a reliable moisture barrier but also provides minor reinforcement for weak floor substrates—transforming them into a resilient base that can support your flooring for years to come.
