Bona Tannin Shield 250ml – Additive for Prime White & Prime Natural

Bona Tannin Shield 250ml – Additive for Prime White & Prime Natural

Bona Tannin Shield is a professional additive designed for use with Bona Prime White and Bona Prime Natural. It is used to help reduce the risk of tannin-related discolouration and unwanted colour bleed from certain wood species when applying light or natural-look primer systems.

The additive is particularly useful when working with tannin-rich timber where colour migration could affect the final appearance of a pale, whitewashed or natural floor finish. By adding Bona Tannin Shield directly to the primer, the system gains additional protection against tannin staining while maintaining the intended visual effect of the chosen Bona primer.
